Mishnah Chullin 12:3-4

Sugya Map

The Mishnah in Chullin 12:3-4 meticulously delineates the parameters and nuances of mitzvat shiluach haken, the command to send away the mother bird from its nest before taking the fledglings or eggs (Deuteronomy 22:6-7). This sugya is a rich tapestry of halakhic conditions, linguistic derivations (derashot), and ethical considerations, often juxtaposed with the mitzvah of kisui hadam (covering the blood).

Core Issues

1. Scope of Obligation:
   • Geographical: Eretz Yisrael and Chutz La'aretz.
   • Temporal: Beit HaMikdash era and post-destruction.
   • Type of Bird: Non-sacred (חולין) vs. sacrificial (קדשים).
   • Nature of Nesting: Wild/undomesticated (שאינן מצויות) vs. domesticated (מצויות), even for typically wild birds (e.g., geese in an orchard vs. house).
   • Kosher Status: Kosher bird; exemption for non-kosher birds or mixed nests.
2. Definition of "Mother" and "Nest":
   • "Mother": Does a male pheasant (קורי) qualify? (R. Eliezer vs. Rabbis).
   • "Hovering": What constitutes "רובצת" (resting upon)? Is physical contact required?
   • "Nest": Can it be just one fledgling or one egg?
3. Conditions of Fledglings/Eggs:
   • Viability: Fledglings must "need their mother" (צריכין לאימן); eggs must be "living" (בני קיימא). This excludes flying fledglings (מפריחין) and unfertilized eggs (מוזרות).
4. Dynamics of Sending:
   • Repetition: If the mother returns, does one send her away again?
   • Intent: Can one intend to take the mother and send the offspring?
   • Reversion: If offspring are returned to the nest, and the mother comes back, is there a renewed obligation?
5. The Lav Shenitak L'Aseh Principle: The prohibition of "לא תקח האם על הבנים" (do not take the mother upon the offspring) is followed by the affirmative command "שלח תשלח את האם" (you shall surely send the mother). This gives rise to a classic debate between Rabbi Yehuda and the Rabbis regarding flogging (malkot) for its violation.
6. Ethical/Theological Dimension: The kal v'chomer (a fortiori) inference from the simple mitzvah of shiluach haken (an issar loss) to more demanding mitzvot, regarding the promise of "That it may be well with you, and that you may prolong your days."

Nafka Mina(s)

Each condition outlined above generates practical nafka mina (halakhic difference):

• Whether one is permitted to take birds from a domestic goose's nest.
• The permissibility of taking eggs from an eagle's nest if the mother is merely nearby but not touching.
• Whether one must send away a male bird if it sits on the eggs.
• The status of an egg found to be unfertilized after the mother was sent.
• Whether one is liable for malkot if they take the mother bird with the offspring.
• The broader conceptual implications for reward and the nature of mitzvot.

Text Snapshot

The Mishnah presents a detailed exposition of shiluach haken, unpacking the biblical command through various conditions and interpretative derivations.

Mishnah Chullin 12:3

היתה מעופפת בזמן שכנפיה נוגעות בקן חייב לשלח. אין כנפיה נוגעות בקן פטור מלשלח. אין שם אלא אפרוח אחד או ביצה אחת חייב לשלח. שנאמר קן קן מכל מקום. היו שם אפרוחים מפריחין או ביצים מוזרות פטור מלשלח. שנאמר והאם רובצת על האפרוחים או על הביצים. מה אפרוחים בני קיימה אף ביצים בנות קיימה יצאו מוזרות. ומה ביצים צריכות לאימן אף האפרוחים צריכין לאימן יצאו מפריחין. שלחה וחזרה שלחה וחזרה אפילו ארבעה וחמשה פעמים חייב לשלח. שנאמר שלח תשלח את האם. אמר הריני נוטל את האם ושולח את הבנים חייב לשלח. נטל את הבנים והחזירן וחזרה האם עליהן פטור מלשלח. לקח את האם עם הבנים רבי יהודה אומר לוקה ואינו משלח. וחכמים אומרים משלח ואינו לוקה. זה הכלל כל מצות לא תעשה שיש בה קום עשה אין לוקין עליה.

Dikduk/Leshon Nuance

• "היתה מעופפת בזמן שכנפיה נוגעות בקן": This phrase precisely defines "רובצת" (resting), clarifying that mere hovering is insufficient unless there is physical contact. The dikduk emphasizes the contact ("נוגעות") as the critical element, not just proximity.
• "קן קן מכל מקום": The repetition of "קן" (nest) is a derasha technique. "מכל מקום" (in any case / from anywhere) typically implies a broadening of the rule, often derived through a gezeirah shavah or ribbui. Here, it expands the requirement from multiple fledglings/eggs (implied by the plural "אפרוחים" and "ביצים" in the verse) to even a single one.
• "אפרוחים מפריחין" / "ביצים מוזרות": These terms define the exclusions. "מפריחין" (flying fledglings) implies fledglings capable of independent flight, not requiring the mother's direct care. "מוזרות" (unfertilized/faulty eggs) refers to eggs incapable of hatching living offspring. The Mishnah's derasha for these exclusions ("מה אפרוחים בני קיימה... ומה ביצים צריכות לאימן...") is a classic hekesh (juxtaposition) and mah matzinu (just as we find) structure.
• "שלח תשלח את האם": The doubling of the verb (an infinitive absolute followed by the finite verb) is a strong grammatical construction in Hebrew, almost always implying emphasis, repetition, or intensity. Here, the Mishnah derives the obligation to send multiple times if the mother returns. This is a common drasha pattern in halakhic midrashim.
• "אמר הריני נוטל את האם ושולח את הבנים": This scenario highlights the specific nature of the mitzvah. The mitzvah is to send the mother, not merely to separate mother and offspring by removing the latter. The dikduk of "את האם" (the mother) in the mitzvah instruction is paramount.
• "לקח את האם עם הבנים... כל מצות לא תעשה שיש בה קום עשה אין לוקין עליה": This establishes the principle of lav shenitak l'aseh. The lav is "לא תקח האם על הבנים" and the aseh is "שלח תשלח את האם." The dikduk of "קום עשה" (arise and perform a positive commandment) emphasizes an active, rectifying positive command that mitigates the negative.

Readings

Rambam on Mishnah Chullin 12:3:1

Rambam offers incisive, though sometimes terse, explanations that often reveal his underlying systematic approach to Halakha.

היתה מעופפת בזמן שכנפיה נוגעות בקן חייב כו': שלחה וחזרה שלחה וחזרה אפילו ארבעה וחמשה כו': שלח מקור והמקור נופל על המעט וההרבה ולפיכך חייב מצד שהוא מקור לשלח אותה ואפילו אלף פעמים וכל ההלכה הזאת מבוארת: (Translation: "If it was hovering, when its wings are touching the nest, one is obligated, etc.: If one sent it and it returned, sent it and it returned, even four or five times, etc.: 'Shalach' (send) is a root, and a root applies to few and many. Therefore, one is obligated, by virtue of it being a root, to send it even a thousand times. And all of this Halakha is clear.")

Rambam's comment, "שלח מקור והמקור נופל על המעט וההרבה ולפיכך חייב מצד שהוא מקור לשלח אותה ואפילו אלף פעמים," is profoundly insightful. He explains the derasha of "שלח תשלח" not merely as a grammatical doubling implying repetition, but by invoking the concept of "מקור" (root/source). The infinitive absolute "שלח" functions as the makor – the core, fundamental command to send. This makor, being an abstract principle, "נופל על המעט וההרבה" (applies to both few and many instances). Therefore, the obligation to send is not limited to four or five times, but extends "אפילו אלף פעמים" – indefinitely, as long as the conditions of the mitzvah are met.

This understanding elevates the derasha from a mere linguistic trick to a philosophical insight into the nature of the commandment itself. The mitzvah is not satisfied by a single act if the underlying situation persists. The makor of "sending" demands the mother's removal whenever she is found "רובצת" over viable offspring that require her care. This perspective aligns with Rambam's general approach of seeking the rational and underlying principles of mitzvot, rather than viewing them as arbitrary decrees. The chiddush here is that the repetition is not an arbitrary number but stems from the perpetual nature of the makor of the mitzvah.

His concluding remark, "וכל ההלכה הזאת מבוארת" (and all of this Halakha is clear), is typical of Rambam. It signifies that the Mishnah's statements are self-evident or well-established in tradition, requiring no further complex derashot or debates beyond what is presented. It also suggests that the logical progression within the Mishnah's rulings is transparent to him, perhaps indicating his comfort with the traditional derashot or a clear mesorah (tradition) underpinning these halakhot.

Tosafot Yom Tov on Mishnah Chullin 12:3:1-4

Tosafot Yom Tov, R. Yom Tov Lipman Heller, often clarifies and expands upon the Mishnah and other commentaries, particularly Bartenura. His comments here delve into linguistic precision and the logic of derashot.

On "מפריחין"

מפריחין . יתכן שדרך העופות שפורחות הרבה ביחד ונמצא כל אחד מפריח לחברו עמו. לכן בא הלשון בהפסול שהוא יוצא: (Translation: "מפריחין (fledglings capable of flying). It is possible that it is the way of birds that many fly together, and it is found that each one causes its fellow to fly with it. Therefore, the language of exclusion is used, which comes out (to exclude).")

The Tosafot Yom Tov here grapples with the plural "מפריחין." While the Mishnah states "אפרוחים מפריחין" (flying fledglings) are exempt, it could be understood to mean individual fledglings capable of flying. However, T.Y.T. offers an interesting sociological observation about birds: "דרך העופות שפורחות הרבה ביחד ונמצא כל אחד מפריח לחברו עמו" (it is the way of birds that many fly together, and each one causes its fellow to fly with it). This suggests that the plural "מפריחין" might not just refer to multiple individual flying fledglings, but to a collective state of fledglings where their collective ability to fly means they no longer require the mother's constant care. The "לכן בא הלשון בהפסול שהוא יוצא" (therefore the language of exclusion is used) implies that this plural form naturally signals an exclusion for a group of fledglings who are collectively independent. The chiddush is understanding the plural not as a numerical count, but as a descriptor of a social dynamic among birds that indicates their independence.

On "והאם רובצת על האפרוחים או על הביצים מה אפרוחים וכו'"

שנאמר והאם רובצת על האפרוחים או על הביצים מה אפרוחים וכו' . ואפרוחים וביצים אורחיה דקרא הוא למנקט רבים ברוב קנים. דאי איפכא דבעינן רבים וקן מ"מ לרבות מפריחים ומוזרות. א"כ נכתוב קרא והאם רובצת עליהם. גמרא: (Translation: "As it is stated: 'And the mother is resting upon the fledglings or upon the eggs.' Just as fledglings etc. 'And fledglings and eggs' – it is the way of the verse (אורחיה דקרא) to use the plural in most nests. For if it were otherwise, that we require many and a nest, meikol makom (nevertheless) to include flying fledglings and unfertilized eggs. If so, the verse should have written 'And the mother is resting upon them.' Gemara.")

Here, T.Y.T. addresses a subtle point regarding the derasha "מה אפרוחים בני קיימה אף ביצים בנות קיימה" and "מה ביצים צריכות לאימן אף האפרוחים צריכין לאימן." The verse uses the plural "אפרוחים או ביצים." One might ask: if the derasha is so specific about "living" and "needing mother," why did the Torah use the plural in the first place? T.Y.T. suggests that the plural "אפרוחים וביצים" is simply "אורחיה דקרא" – the way the Torah typically speaks, using the plural because most nests contain multiple fledglings or eggs. It's descriptive, not prescriptive of a minimum quantity.

He then presents a counter-argument: "דאי איפכא דבעינן רבים וקן מ"מ לרבות מפריחים ומוזרות" (For if it were otherwise, that we require many, and a nest meikol makom to include flying fledglings and unfertilized eggs). This sentence is dense. He seems to be saying: if the plural were halakhically significant (i.e., requiring multiple fledglings/eggs for the mitzvah), then the derasha that excludes "מפריחים" and "מוזרות" (which also might be multiple) would be problematic. The point of the derasha is to define what kind of fledglings/eggs count, not how many. If the Torah intended to broadly include all types of fledglings/eggs when plural, it would have simply said "והאם רובצת עליהם" (and the mother is resting upon them), without specifying "אפרוחים או ביצים." The specific mention implies a distinction and a need for definition, which the derasha provides. The chiddush is that the plural form in the verse is a general linguistic convention and does not override the specific derashot that define the quality of the offspring required for the mitzvah.

On "שלח תשלח"

שנאמר שלח . לשון הר"ב שנאמר שלח ולעולם משמע. ותשלח דרשינן לה לקמן. וז"ל הרמב"ם שלח מקור והמקור נופל על המעט וההרבה. ועי' בכ"מ שם [פי"ג מה"ש]: (Translation: "As it is stated: 'Shalach.' The language of the Rav (Bartenura) is 'as it is stated: Shalach,' implying forever. And 'Tishlach' we derive later. And this is the language of the Rambam: 'Shalach' is a root, and a root applies to few and many. See in Kesef Mishneh there [Perek 13 of Hilchot Shechitah].")

T.Y.T. here clarifies the derasha of "שלח תשלח" by referencing Bartenura ("ולעולם משמע" - implying forever/always) and directly quoting Rambam's explanation of "שלח מקור." He notes that Bartenura, in his commentary, might have initially focused on "שלח" as the continuous command, and Tishlach as the repetition. T.Y.T. then highlights that Rambam's interpretation of "שלח מקור" provides a deeper, more fundamental reason for the indefinite repetition. This cross-referencing shows how later commentators build upon and harmonize the insights of earlier authorities, offering a comprehensive understanding. The chiddush is the synthesis of Bartenura's "forever" with Rambam's "makor" concept, showing a unified understanding of indefinite obligation.

Mishnat Eretz Yisrael on Mishnah Chullin 12:3:1-5

Mishnat Eretz Yisrael (MEI), a modern critical commentary, offers a fresh perspective, often questioning traditional derashot and proposing alternative interpretations rooted in historical-philological analysis and the ethical dimension of Halakha.

On "היתה מעפעפת בזמן שכנפיה נוגעות בקן חייב לשלח" and "אין שם אלא אפרוח אחד או ביצה אחת חייב... שנאמר קן קן מכל מקום"

היתה מעפעפת בזמן שכנפיה נוגעות בקן חייב לשלח – התנא מפרש את מילות המקרא "אם על בנים" וקובע ש"על" משמעו ממש רביצה על הביצים, אבל גם אם האם מרפרפת עליהן היא נחשבת לרובצת. אין כנפיה נוגעות בקן פטור מלשלח – מצב זה אינו בכלל אם על בנים, וכן בתוספתא (פ"י ה"י, עמ' 512) ובספרי שנצטט בסוף הפרק. אין שם אלא אפרוח אחד או ביצה אחת חייב – אף על פי שאין כאן אפרוחים (לשון רבים), שנאמר קן קן מכל מקום – וכן הדרשה בספרי דברים (רכו, עמ' 259). לכאורה התנא דורש גזרה שווה בין הפסוק "כי יקרא קן צפור לפניך" (דברים כב ו) לבין פסוק אחר כלשהו. ברם "קן" נזכר בתנ"ך רק עוד פעמיים: בישעיהו טז ב, "והיה כעוף נודד קן משלח תהיינה בנות מואב מעברֹת לארנון", ובתהילים פד ד, "גם צפור מצאה בית ודרור קן לה אשר שתה אפרֹחיה את מזבחותיך ה' צבאות מלכי ואלהי". בשני פסוקים אלו המילה "קן" מקבילה ל"ציפור" (ביחיד). המינוח "מכל מקום" במדרשי התנאים בא אמנם עם גזרה שווה... ברם אין זה רגיל שחכמים ידרשו גזרה שווה בין פסוק בתורה לפסוק בנביאים או בכתובים. על דרך השערה ניתן היה להציע כי הדרשה הייתה "קן מכל מקום", ללא גזרה שווה, אבל אין לתיקון כזה בסיס בעדי הנוסח וקשה לקבלו. על כל פנים, הדרשה קשה הרבה יותר. רגיל היה לדרוש "אפרוחים מיעוט שניים", וכן הבבלי מייחס לחכם אלמוני, "ההוא מרבנן", דרשה חריגה זו שאינה זוכה לתגובת הבבלי. יתר על כן, התלמוד מציע דרשה חילופית למילים "קן" "קן". לפי דרכנו השאלה איננה קשה. ההלכה לא נלמדה מהפסוק, ואין היא פירוש לו. ההלכה הייתה ידועה ונבעה מסיבות אחרות, ורק הצמידוה לפסוקים אלו. למה באמת נקבעה ההלכה? כל דין שילוח האם הוא גילוי של רחמים, או נכון יותר גילוי של הצורך לאזן בין הרחמים וצורכי עופות הבר מחד גיסא לבין צורכי האדם מאידך גיסא. לו היו הרחמים הגורם היחיד היה הציד נאסר כליל. אלא הציד נחוץ, וחכמים רוצים לרסנו. שילוח אם שיש לה אפרוח אחד הוא חיזוק מרכיב הרחמים, וזו דרכם של חכמים (בעקבות התורה) לבטא את האיזון הדרוש. מכל מקום המצווה כתובה בתורה, וגם אם לא היה לה כל הסבר לא היה מעמדה נפגע בעיני חכמים. (Translation: "If it was hovering, when its wings are touching the nest, one is obligated to send – The Tanna interprets the words of the verse 'mother upon offspring' and determines that 'upon' means actual resting on the eggs, but even if the mother flutters over them, she is considered resting. If its wings are not touching the nest, one is exempt from sending – This situation is not included in 'mother upon offspring,' and similarly in the Tosefta (10:10, p. 512) and in Sifrei, which we will cite at the end of the chapter. If there is only one fledgling or one egg, one is obligated – even though there are no 'fledglings' (plural), as it is stated 'nest, nest, in any case' – and similarly the derasha in Sifrei Devarim (226, p. 259). Ostensibly, the Tanna derives a gezeirah shavah between the verse 'If a bird's nest happens before you' (Deuteronomy 22:6) and some other verse. However, 'nest' (קן) is mentioned in Tanakh only two other times: in Isaiah 16:2, 'And it shall be like a wandering bird, a nest cast forth, so shall the daughters of Moab be at the fords of Arnon,' and in Psalms 84:4, 'Even the sparrow has found a house, and the swallow a nest for herself, where she may lay her young, at Your altars, O Lord of Hosts, my King and my God.' In both these verses, the word 'nest' parallels 'bird' (singular). The term 'מכל מקום' in Tannaitic midrashim does indeed appear with a gezeirah shavah... However, it is not common for Sages to derive a gezeirah shavah between a verse in the Torah and a verse in Nevi'im or Ketuvim. Speculatively, one might suggest that the derasha was 'קן מכל מקום' without a gezeirah shavah, but there is no textual basis for such a correction and it is difficult to accept. In any case, the derasha is much more difficult. It was common to derive 'אפרוחים מיעוט שניים' (fledglings implies a minimum of two), and the Babylonian Talmud attributes this unusual derasha, which receives no response in the Babylonian Talmud, to an anonymous sage ('ההוא מרבנן'). Furthermore, the Talmud offers an alternative derasha for the words 'קן' 'קן'. According to our approach, the question is not difficult. The halakha was not learned from the verse, nor is it an interpretation of it. The halakha was known and derived from other reasons, and was only attached to these verses. Why was the halakha truly established? The entire law of sending away the mother is a revelation of compassion, or more accurately, a revelation of the need to balance compassion and the needs of wild birds on the one hand with human needs on the other. If compassion were the only factor, hunting would be completely forbidden. But hunting is necessary, and the Sages wish to restrain it. Sending away a mother with only one fledgling strengthens the element of compassion, and this is the way of the Sages (following the Torah) to express the necessary balance. In any case, the mitzvah is written in the Torah, and even if it had no explanation, its status would not be diminished in the eyes of the Sages.")

MEI's commentary here is a significant departure from traditional peshat and derash interpretations. He first clarifies the definition of "מעופפת" (hovering) as requiring physical contact for the mitzvah to apply. His more profound chiddush comes with the derasha "קן קן מכל מקום." He identifies the difficulty of a gezeirah shavah between a Torah verse and verses in Nevi'im or Ketuvim (Isaiah 16:2, Psalms 84:4) which are the only other places "קן" appears. He notes that while "מכל מקום" often signals a gezeirah shavah, this specific one is problematic due to the source texts.

MEI then proposes a radical idea: "ההלכה לא נלמדה מהפסוק, ואין היא פירוש לו. ההלכה הייתה ידועה ונבעה מסיבות אחרות, ורק הצמידוה לפסוקים אלו." (The halakha was not learned from the verse, nor is it an interpretation of it. The halakha was known and derived from other reasons, and was only attached to these verses.) This suggests that many derashot, particularly problematic ones, might serve as asmachta (supportive references) rather than direct sources for halakhot that were already known through mesorah or sevara.

The "other reasons" he posits are ethical: "כל דין שילוח האם הוא גילוי של רחמים, או נכון יותר גילוי של הצורך לאזן בין הרחמים וצורכי עופות הבר מחד גיסא לבין צורכי האדם מאידך גיסא." The mitzvah is a manifestation of compassion and a balance between human needs (hunting) and the welfare of animals. Strengthening the compassion element, even for a single fledgling, reinforces this balance. This chiddush offers a meta-halakhic framework for understanding the purpose of many mitzvot, placing ethical considerations at their core, even if the textual derivation is seen as secondary.

On "היו שם אפרוחים מפריחין או ביצים מוזרות"

היו שם אפרוחים מפריחין או ביצים מוזרות – ביצה מוזרה היא כנראה ביצה שיש בה פגם או שהיא אינה של עוף אלא של שרץ כלשהו. פטור מלשלח שנאמר והאם רובצת על האפרוחים או על הביצים (דברים כב ו), מה אפרוחים בני קיימה אף ביצים בנות קיימה יצאו מוזרות – המשנה מנוסחת בלשון וסגנון של מדרש תנאים. ומה ביצים צריכות לאימן – ברוב עדי הנוסח נוסף "אף האפרוחים צריכין לאמן", יצאו מפריחים – אפרוח מפריח הוא מי שיצא מכלל אפרוח אך טרם הפך לעוף של ממש. כיום היינו מכנים אותם גוזלים בוגרים. הם מסוגלים לדדות, ולפרוח לטווח קצר, אך לא ממש לעוף. (Translation: "If there were flying fledglings or unfertilized eggs – An 'unfertilized egg' (ביצה מוזרה) is likely an egg with a defect or one that is not from a bird but from some creeping creature. One is exempt from sending, as it is stated: 'And the mother is resting upon the fledglings or upon the eggs' (Deuteronomy 22:6), 'just as fledglings are viable, so too eggs must be viable' – this excludes unfertilized eggs. The Mishnah is formulated in the language and style of a Tannaitic Midrash. 'And just as eggs need their mother' – in most manuscript versions, 'so too fledglings need their mother' is added – 'this excludes flying fledglings.' A 'flying fledgling' (אפרוח מפריח) is one that has emerged from the stage of a fledgling but has not yet become a full bird. Today we would call them mature nestlings. They are capable of waddling and flying short distances, but not truly flying.")

MEI provides a practical definition for "ביצה מוזרה" (faulty/unfertilized egg) and "אפרוח מפריח" (flying fledgling). He clarifies that "מוזרות" could mean either a defective egg or even an egg of a different, perhaps non-kosher, creature. For "מפריח," he offers a nuanced definition: not fully independent, but "גוזלים בוגרים" (mature nestlings) capable of short flights and waddling, indicating they no longer rely entirely on the mother for survival in the nest. This is a crucial clarification for halakha l'maaseh. The chiddush here is the precise zoological/behavioral definition of "מפריח" and "מוזר," which are essential for applying the Mishnah's derashot correctly.

On "שלחה וחזרה... אפילו ארבעה וחמשה פעמים חייב לשלח שנאמר שלח תשלח"

שלחה וחזרה שלחה וחזרה אפילו ארבעה – ברוב עדי הנוסח "וחמשה", פעמים חייב לשלח שנאמר שלח תשלח – דברים כב ו. מהכפילות התנא לומד שיש לשלח אפילו פעמים מספר. מבנה זה רגיל במדרשי הלכה שמכפל מילים לומדים שיש לקיים את המצווה או האיסור אפילו ארבע וחמש פעמים. ארבע וחמש אינן גבול עליון אלא מספר של ריבוי, "פעמים רבות" 7 ראו פירושנו ליבמות פי"ג מ"א, ועוד הרבה. בתוספתא ההלכה חוזרת בתוספת קלה: "1. אפרוחים שפרחו ואין צריכין לאימן פטור מלשלח. 2. נטל את האם ולא הספיק ליטול את הבנים עד שמתה או עד שנעשו טרפה פטור מלשלח" (פ"י הי"א, עמ' 512). ההלכה הראשונה מופיעה במשנה והתוספתא מוסיפה הגדרה מדויקת יותר. ההלכה השנייה איננה במשנה. (Translation: "If one sent it and it returned, sent it and it returned, even four – in most manuscript versions 'and five' – times, one is obligated to send, as it is stated: 'You shall surely send' (Deuteronomy 22:6). From the doubling, the Tanna learns that one must send even multiple times. This structure is common in halakhic midrashim, where from the doubling of words one learns that the mitzvah or prohibition must be performed even four or five times. Four and five are not an upper limit, but a number of multiplicity, 'many times' (see our commentary on Yevamot 13:1, and many others). In the Tosefta, the halakha reappears with a slight addition: '1. Fledglings that have flown and do not need their mother, one is exempt from sending. 2. If one took the mother and did not manage to take the offspring until it died or became a treifah, one is exempt from sending' (10:11, p. 512). The first halakha appears in the Mishnah, and the Tosefta adds a more precise definition. The second halakha is not in the Mishnah.")

MEI echoes the traditional understanding of "שלח תשלח" as indicating repetition, clarifying that "ארבעה וחמשה" is not a limit but a general expression for "many times." He also brings in the Tosefta as a parallel source, noting its slight additions or clarifications, particularly the case where the offspring die or become treifah (non-kosher due to a defect) before they can be taken, which leads to exemption. This demonstrates the intertextual nature of halakhic development. The chiddush here is the emphasis on "ארבע וחמש אינן גבול עליון אלא מספר של ריבוי," reinforcing Rambam's idea of indefinite obligation.

Friction

The Mishnah, despite its seemingly straightforward exposition, presents several points of conceptual friction that have engaged Rishonim and Acharonim. We will focus on two major areas: the epistemological status of derashot (specifically "קן קן מכל מקום") and the application of lav shenitak l'aseh in the context of shiluach haken.

Kushya 1: The Epistemological Status of "קן קן מכל מקום"

The Mishnah derives that "אין שם אלא אפרוח אחד או ביצה אחת חייב לשלח. שנאמר קן קן מכל מקום." This derasha expands the obligation to a single fledgling or egg, despite the plural "אפרוחים או ביצים" in the verse. As Mishnat Eretz Yisrael (MEI) keenly observes, this derasha is problematic if interpreted as a gezeirah shavah. The term "מכל מקום" often signifies a gezeirah shavah, where a common word in two different contexts allows for an inference. However, the word "קן" (nest) appears only twice outside of Deuteronomy 22:6-7: Isaiah 16:2 and Psalms 84:4. Deriving halakha from a gezeirah shavah between Torah and Nevi'im/Ketuvim is highly unusual and generally avoided by the Sages. Furthermore, the contexts in Isaiah and Psalms do not clearly lend themselves to a direct halakhic comparison.

The Friction:

1. Source Mismatch: If "קן קן" is a gezeirah shavah, its reliance on Nevi'im/Ketuvim for a Torah mitzvah is anomalous. Traditional gezeirah shavah requires both sources to be from the Torah, or at least from the same textual corpus, and often with specific kabbalah (tradition) to validate them.
2. Linguistic Ambiguity: What does "מכל מקום" truly signify if not a gezeirah shavah? If it's merely a general rhetorical flourish, how does it effect a halakhic expansion that contradicts the plural form in the verse ("אפרוחים")?
3. Alternative Derashot: The Gemara (Chullin 13b) provides an alternative derasha for "קן קן" that does not rely on Nevi'im/Ketuvim, suggesting the Sages themselves recognized the difficulty. This highlights the fluidity and multiplicity of derashot, making the Mishnah's specific choice of "מכל מקום" (and its implied gezeirah shavah) a point of contention.
4. MEI's Challenge: MEI's bold claim that "ההלכה לא נלמדה מהפסוק... ההלכה הייתה ידועה ונבעה מסיבות אחרות, ורק הצמידוה לפסוקים אלו" challenges the very notion of derasha as the primary source for Halakha in such instances. This reorients the relationship between textual exegesis and received tradition/ethical intuition.

Terutzim (Resolutions):

Terutz 1: Defending the Gezeirah Shavah / Alternative Understanding of "מכל מקום"

One approach is to defend the traditional understanding, or offer a more nuanced interpretation of "מכל מקום."

• Specific Kabbalah: It is possible that this specific gezeirah shavah, despite its unusual sources, was transmitted via kabbalah (tradition) from Sinai. While rare, such exceptions are not entirely unheard of in the corpus of derashot. The very existence of the derasha in Sifrei Devarim 226 (cited by MEI) suggests it's an established Tannaitic tradition. The mesorah itself might be the validation, overriding the general rule against cross-corpus gezeirah shavah.
• "מכל מקום" as a General Expansionary Term: Perhaps "מכל מקום" does not strictly imply a gezeirah shavah in this context but functions as a general ribbui (inclusion) term. The repetition of "קן" itself ("כי יקרא קן צפור לפניך... קן") could be the basis for ribbui, and "מכל מקום" simply emphasizes the breadth of this inclusion, meaning "a nest in any and all circumstances," even if it contains only one. This interpretation avoids the problematic gezeirah shavah and relies on the inherent redundancy of the verse as a signal for expansion. This is similar to how "איש איש" (any man) in other contexts expands the scope to include women, tumtumim, and androginos (Mekhilta d'Rabbi Yishmael, Yitro, Masekhta d'Bachodesh, p. 231). The doubling of "קן" implies "nest" in its most minimal form, not necessarily a full one with many occupants.
• Grammatical Redundancy for Emphasis: The repetition of a noun like "קן קן" might be seen as a form of emphatic redundancy, similar to the infinitive absolute. Just as "שלח תשלח" emphasizes the action of sending, "קן קן" emphasizes the concept of "nest" in its most inclusive sense, even a minimal one.

Terutz 2: Embracing MEI's "Asmachta" Approach

A more radical, yet compelling, resolution is to accept MEI's premise that the halakha concerning a single fledgling/egg was not derived from the passuk but was known from mesorah or sevara, and the passuk serves as an asmachta.

• The Primacy of Sevara and Mesora: This view posits that fundamental halakhot can originate from intuitive ethical principles (like compassion, as MEI suggests for shiluach haken) or an unbroken chain of tradition, even if they are later "attached" to verses for mnemonic or homiletic purposes. The mitzvah of shiluach haken is indeed an expression of divine compassion, and it would be inconsistent for this compassion to be withheld merely because there's only one fledgling. The sevara would dictate that the mother's attachment and the offspring's vulnerability are paramount, regardless of quantity.
• Dealing with Problematic Derashot: This approach offers a framework for understanding derashot that seem forced or difficult. Instead of trying to force a peshat or complex derasha onto a verse, it allows for the possibility that the derasha is not the origin but rather a post-facto textual support. This doesn't diminish the mitzvah's divine origin, but rather shifts the understanding of how Halakha is developed and transmitted. It acknowledges that the Torah gives us principles, and the Sages, through mesorah and sevara, apply and detail those principles, sometimes using textual hooks (asmachtot) for existing halakhot.
• Implications for Halakhic Method: If accepted, this method suggests a dynamic interplay between revealed text, oral tradition, and ethical reasoning in the formation of Halakha. The derasha in the Mishnah, while perhaps not the source, still functions to legitimize and connect the known halakha to the written Torah, demonstrating its divine sanction.

Kushya 2: The Lav Shenitak L'Aseh Principle and Its Application in Shiluach Haken

The Mishnah presents a foundational dispute regarding lav shenitak l'aseh (a negative commandment linked to an affirmative one): "לקח את האם עם הבנים רבי יהודה אומר לוקה ואינו משלח. וחכמים אומרים משלח ואינו לוקה. זה הכלל כל מצות לא תעשה שיש בה קום עשה אין לוקין עליה." The lav is "לא תקח האם על הבנים" (Deut. 22:6) and the aseh is "שלח תשלח את האם" (Deut. 22:7).

The Friction: The core debate revolves around whether the aseh of sending the mother after one has already taken her with the offspring (thereby violating the lav) truly constitutes a "קום עשה" that rectifies the lav and thus exempts one from malkot (flogging).

1. Nature of Rectification: In classic lavin shenitaku l'aseh (e.g., returning a stolen item, hashavat aveida), the aseh directly undoes or corrects the transgression of the lav. If one steals, returning the item rectifies the theft. Here, the act of "taking the mother with the offspring" is a completed lav. Sending the mother subsequently (if she returns, as per the context of shiluach teshallach) doesn't "undo" the original act of taking them together. It's a separate action, a new mitzvah performed in a different context. How can it exempt from the malkot incurred for the initial lav?
2. Timing of the Aseh: The aseh of "שלח תשלח" is a preventative measure, to be done before taking the offspring. If one has already violated the lav by taking both, the moment for the aseh as a precondition is past. The aseh in the verse is "send the mother, and then take the offspring." If one takes the mother and offspring first, the aseh cannot be performed in its original sequence.
3. R. Yehuda's Logic: R. Yehuda's position ("לוקה ואינו משלח") implies that the violation of the lav is absolute and incurs malkot, and the aseh cannot rectify it. Perhaps he views the aseh as no longer applicable in a scenario where the lav was actively transgressed, or that the aseh is not a "קום עשה" in the sense of rectifying this specific lav. Once you took the mother, the mitzvah to send her before taking the young is gone. If she returns later, that's a new instance.
4. Rabbis' Logic: The Rabbis ("משלח ואינו לוקה") clearly apply the lav shenitak l'aseh principle. They must see the aseh as a continuous obligation to separate the mother from the offspring, even after the lav has been violated. The principle "כל מצות לא תעשה שיש בה קום עשה אין לוקין עליה" needs to be understood broadly.

Terutzim (Resolutions):

Terutz 1: A Broad Understanding of "Lav Shenitak L'Aseh" (Rabbis' View)

The Rabbis' position, which is accepted halakha, requires a broad understanding of lav shenitak l'aseh.

• The Aseh as a State of Separation: The lav is "לא תקח האם על הבנים" – it prohibits the state of possessing both the mother and offspring together in the nest. The aseh, "שלח תשלח את האם," is the command to create the state of separation. Even if one initially violates the lav by taking them together, the aseh is still available to rectify the state of transgression. By sending the mother away (if she returns), one is fulfilling the underlying positive command to ensure separation, thereby fulfilling the aseh that is linked to the lav. The aseh doesn't undo the act of taking, but it rectifies the condition that the lav sought to prevent.
• "קום עשה" as a Remedial Action: This interpretation views "קום עשה" not necessarily as undoing the original act of transgression, but as a remedial action that can be performed after the lav is transgressed, which fulfills the spirit of the mitzvah and hence removes the malkot. For example, hashavat aveida (returning a lost item) is a lav shenitak l'aseh. If one initially ignores a lost item (violating a lav against ignoring), the aseh is to pick it up and return it. The aseh comes after the initial failure to act, and rectifies the situation. Similarly, here, the aseh to send the mother (if she returns) is a remedial action that brings about the desired state of separation.
• The Aseh is Not Conditional on No Prior Lav: The Rabbis might hold that the aseh of shiluach is an independent obligation that applies whenever the conditions are met (mother on viable offspring), even if the situation arose through a prior lav. The lav forbids taking them together. The aseh commands sending the mother. If one transgressed the lav, they are liable for malkot. But if the mother returns, the aseh becomes active again. The Rabbis' "משלח ואינו לוקה" implies that the act of sending now somehow retroactively impacts the malkot for the original taking. This suggests that the aseh itself is the ultimate goal, and its performance, even delayed, overrides the punishment for the lav.

Terutz 2: R. Yehuda's Stricter View

R. Yehuda's position ("לוקה ואינו משלח") suggests a stricter interpretation of lav shenitak l'aseh or a unique characteristic of shiluach haken.

• "Lav" and "Aseh" as Sequential: R. Yehuda might understand the lav and aseh as strictly sequential. The lav says "do not take the mother upon the offspring," and the aseh says "send the mother, then take the offspring." If one violates the lav by taking both, they have foregone the opportunity to perform the aseh in its prescribed manner before taking. Therefore, the aseh no longer applies in a way that can mitigate malkot. The aseh of "שלח תשלח" is for one who finds the nest and has the opportunity to perform the mitzvah correctly. One who actively transgresses the lav by taking them together has fundamentally altered the situation such that the aseh cannot rectify it in the same way.
• No Direct Rectification: R. Yehuda could argue that sending the mother, if she returns after being taken, is not a direct rectification of the act of taking the mother with the offspring. The transgression was the initial taking. Sending her back is a new act, not an undoing of the first. Therefore, the malkot for the original act are still incurred.
• The Aseh as a Precondition: Perhaps R. Yehuda sees the aseh as a precondition for taking the offspring, not as a general command to separate them if they are together by any means. Once the precondition is violated, the aseh for this specific instance is lost in its power to remove malkot. The mitzvah of shiluach haken is about initiating the separation correctly, not remedying a transgression.

The Rabbis' view ultimately prevails, highlighting the expansive nature of lav shenitak l'aseh where the affirmative command, even if performed subsequently, is seen as sufficiently linked to the negative command to avert malkot. This reflects a general leniency in halakha to prefer the performance of a mitzvah over the imposition of punishment, whenever a clear link between a lav and an aseh can be established.

Intertext

The Mishnah's discussion of shiluach haken resonates across various strata of Jewish literature, from Tanakh to later halakhic codes and philosophical treatises, revealing its multifaceted significance.

1. Tanakh: The Command's Context in Deuteronomy 22:6-7

The foundational text is, of course, Deuteronomy 22:6-7. Its placement within Parshat Ki Teitzei is highly significant. This parsha is replete with a diverse array of mitzvot, many of which emphasize ethical conduct, social responsibility, and compassion, even towards animals.

• Deuteronomy 22:1-4 (Hashavat Aveida & Perika): Just a few verses earlier, the Torah commands hashavat aveida (returning a lost item) and perika (helping an animal whose burden has fallen). Both are mitzvot that involve compassion and practical assistance for others' property and welfare. While shiluach haken applies to wild animals and is not about property, the thematic thread of caring for animals and not causing undue suffering is palpable. The kal v'chomer in our Mishnah (comparing shiluach haken to "demanding mitzvot") highlights this, implying that shiluach haken, despite its apparent simplicity, embodies a profound ethical principle.
• "למען ייטב לך והארכת ימים" (That it may be well with you, and that you may prolong your days): This phrase, the reward for shiluach haken, is shared only with mitzvot of honoring parents (Deut. 5:16) and honest weights (Deut. 25:15). This unique coupling elevates shiluach haken beyond a mere ritual, suggesting it touches upon fundamental principles of justice, compassion, and the proper order of the world. The reward's rarity hints at a deeper significance, prompting philosophical inquiry into its underlying reasons (e.g., Rambam's Moreh Nevuchim).

2. Talmud/Midrash: Expanding and Debating the Derashot

The Gemara (Chullin 13b-14a) extensively discusses and debates the Mishnah's derashot, often offering alternative interpretations or elaborations.

• "קן קן מכל מקום" (Chullin 13b): The Gemara explores the derasha for a single egg/fledgling. While the Mishnah states "קן קן מכל מקום," implying a gezeirah shavah, the Gemara offers a different derasha: "קן לרבות אפרוח אחד וביצה אחת, קן קן שמרבה על הכל" (Nest to include one fledgling and one egg; nest, nest to include everything). This alternative avoids the problematic gezeirah shavah to Nevi'im/Ketuvim and supports MEI's observation about the difficulty of the Mishnah's phrasing. It implies that the doubling of the word "קן" within the same verse is sufficient for the expansion, rather than requiring a reference to external texts. This highlights the rabbinic method of seeking the most textually robust derasha.
• "שלח תשלח" (Chullin 13b and Bava Metzia 32b): The Gemara explicitly states that "שלח תשלח" means "אפילו מאה פעמים" (even a hundred times), supporting the Mishnah's "אפילו ארבעה וחמשה פעמים" as a rhetorical plural for "many." This interpretation is consistent with how doubled verbs are often understood in derashot. The Tosafot Yom Tov's reference to Bava Metzia 32b is relevant here, as that sugya discusses the general principle of lav shenitak l'aseh.
• "Lav Shenitak L'Aseh" (Bava Metzia 32b and Sanhedrin 81b): The principle that "כל מצות לא תעשה שיש בה קום עשה אין לוקין עליה" is a cornerstone of rabbinic law. Bava Metzia 32b (cited by T.Y.T. implicitly) delves into its applications, such as hashavat aveida or perika (unloading a fallen animal). In these cases, a lav (e.g., "לא תראה את חמור אחיך... והתעלמת מהם" - you shall not see your brother's donkey... and ignore them) is followed by an aseh ("הקם תקים עמו" - you shall surely help him lift it). The parallel is striking: just as helping to lift the burden (an aseh) rectifies the failure to help (the lav), sending the mother (an aseh) rectifies the failure to send her before taking (the lav). This intertextual comparison validates the Rabbis' position in our Mishnah as part of a broader halakhic principle.

3. Rishonim & Acharonim: Philosophical Underpinnings and Halakhic Codification

• Rambam, Moreh Nevuchim III:48: Rambam famously provides a philosophical rationale for shiluach haken, stating that its purpose is to inculcate compassion and prevent cruelty to animals: "כי רחמיו של הקב"ה על כל מעשיו... וזה מפורש במצוות שילוח הקן... שהצער שיש לבהמות בנטילת בניה לעיניהם גדול מאד." (For the compassion of the Holy One, Blessed be He, extends to all His creatures... This is explicit in the mitzvah of sending away the nest... for the pain that animals feel when their offspring are taken before their eyes is very great.) He also argues against taking the mother and offspring simultaneously to avoid destroying the species, as birds would abandon nesting in places where this occurs. This machshava (philosophical thought) directly informs the halakhic details of the Mishnah, such as excluding "flying fledglings" or "unfertilized eggs" – if the offspring are not viable or independent, the mother's pain of separation is less significant, or the species is not truly at risk. This strengthens MEI's sevara argument.
• Sefer HaChinuch Mitzvah 294: The Sefer HaChinuch generally follows Rambam's rationale, emphasizing compassion and the development of positive character traits in humans. He also highlights the unique reward of "prolonging days," suggesting that such mitzvot that cultivate universal compassion are fundamental to human existence and societal well-being. He also notes the prohibition against taking the mother even for a mitzvah (like purifying a metzora), underscoring the strength of the shiluach haken command.
• Shulchan Aruch, Yoreh De'ah 228: This halakhic code synthesizes the Mishnah, Gemara, and Rishonim into practical law. It codifies the conditions for shiluach haken (e.g., kosher bird, wild, eggs/fledglings needing mother), the definition of "hovering" (wings touching), the requirement to send multiple times, and the Rabbis' view on lav shenitak l'aseh (one sends and is not flogged). It serves as the ultimate practical manifestation of the Mishnah's teachings.

The interplay of these texts demonstrates how shiluach haken moves from a simple biblical command to a complex halakhic system, underpinned by profound ethical and philosophical considerations, and ultimately codified for practical application.

Psak/Practice

The intricate details of Mishnah Chullin 12:3-4, honed by subsequent Gemara and Rishonim, coalesce into concrete halakha l'maaseh, primarily codified in Shulchan Aruch, Yoreh De'ah 228.

Key Halakhic Rulings

1. Scope of Obligation:
   • Universal Application: The mitzvah applies both in Eretz Yisrael and Chutz La'aretz, and whether the Temple stands or not (Shulchan Aruch YD 228:1). This underscores its fundamental, non-land-dependent nature.
   • Bird Type: It applies only to kosher, non-sacrificial birds. Non-kosher birds (e.g., crows, eagles) are exempt, as are birds designated for sacrifices (YD 228:2).
   • Wild vs. Domesticated: Crucially, it applies only to birds "שאינן מצויות" (not readily available), meaning wild birds. Geese or chickens that nested in an orchard are considered wild for this purpose, but if they nested in a house, or if they are domesticated pigeons (yonei hardisei'ot), one is exempt (YD 228:3). The determining factor is the potential for flight and independence from human care, not species.
2. Definition of "Mother" and "Nest":
   • "Hovering" (מעופפת): The mother bird must be "רובצת" (resting) upon the eggs or fledglings. The Mishnah defines this as "כנפיה נוגעות בקן" (its wings are touching the nest). If the wings are not touching, even if it's hovering closely, one is exempt (YD 228:4).
   • "One Fledgling/Egg": Following the derasha "קן קן מכל מקום," even a single fledgling or egg obligates shiluach haken (YD 228:5).
   • Male Pheasant (קורי): The Rabbis' view is accepted: one is exempt from sending away a male pheasant, as the mitzvah specifically refers to "האם" (the mother) (YD 228:2).
3. Conditions of Fledglings/Eggs:
   • Viability & Dependence: The eggs must be bnei kayama (viable, capable of hatching), and the fledglings must tzrichin l'iman (need their mother). This excludes bizim muzarot (unfertilized/defective eggs) and afrochim mafrichin (fledglings capable of flying) (YD 228:5). The psak follows the Mishnah's specific derashot.
4. Dynamics of Sending:
   • Repetition: If the mother returns, one is obligated to send her away again, "אפילו כמה פעמים" (even many times), following the derasha of "שלח תשלח" (YD 228:6).
   • Intent and Reversion: If one says "I'm taking the mother and sending the offspring," he is still obligated to send the mother (YD 228:7). If one took the offspring, returned them, and the mother returned, one is exempt from sending again (YD 228:8).
5. The Lav Shenitak L'Aseh: The psak follows the Rabbis' view: if one takes the mother with the offspring, one sends the mother (if she returns) and is not flogged. This is because "כל מצות לא תעשה שיש בה קום עשה אין לוקין עליה" (YD 228:9). This reflects a general halakhic principle where the ability to rectify a transgression via a positive command mitigates the more severe punishment of flogging.
6. Prohibition against Taking for a Mitzvah: One may not take the mother with the offspring even for the mitzvah of purifying a metzora, which requires two live kosher birds (YD 228:9). This emphasizes the absolute nature of the shiluach haken prohibition.

Meta-Psak Heuristics

• The Kal V'Chomer of Reward: The Mishnah concludes with the kal v'chomer that if shiluach haken (a "simple mitzvah," costing only an issar) warrants "that it may be well with you, and that you may prolong your days," then "demanding mitzvot" certainly do. This is not a halakha l'maaseh in terms of specific actions, but a profound meta-psak heuristic. It teaches that the value and reward of mitzvot are not directly proportional to their apparent difficulty or material cost. Even seemingly minor acts of compassion or adherence to divine will carry immense spiritual weight and promise. This encourages diligence in all mitzvot, regardless of their perceived "weight."
• Balance of Compassion and Necessity: As MEI insightfully notes, the mitzvah embodies a balance between divine compassion (rachamim) towards animals and the legitimate needs of humans (e.g., for food, implying the permissibility of hunting). The specific conditions (kosher, non-sacred, wild, viable offspring) reflect this balance. We are permitted to benefit from the animal kingdom, but with a restraint that acknowledges the suffering of creatures and safeguards their continued existence. This heuristic informs our general approach to environmental ethics and animal welfare in Jewish thought.
• The Supremacy of the Aseh: The ruling on lav shenitak l'aseh (Rabbis' view) highlights a broader principle: when a lav is linked to an aseh, the performance of the aseh is paramount and often takes precedence in mitigating punitive measures. This reflects a preference for positive action and rectification over mere punishment within the halakhic system.

In practice, shiluach haken is a relatively rare mitzvah for most people today, given urbanization and changed lifestyles. However, its principles continue to inform Jewish ethical thought regarding animal welfare, the interpretation of mitzvot, and the balance between human needs and the broader created order.

Takeaway

The sugya of shiluach haken exemplifies the rigorous textual analysis and profound ethical considerations embedded in Halakha, demonstrating how even seemingly minor mitzvot are intricately detailed and carry immense spiritual weight, balancing human needs with divine compassion for all creation. Its derashot and debates highlight the dynamic interplay between received tradition, textual exegesis, and moral reasoning in shaping Jewish law.
