Mishnah Bekhorot 5:4-5

Sugya Map

• Issue: The halakhic status and proper disposition of a bekhor (firstborn animal) or other kodashim (consecrated animals) that develop a blemish, particularly when that blemish is mum b'yedei adam (a blemish caused by a person). This expands into questions of ne'emanut (credibility) regarding who can testify about the blemish's origin and when, as well as the psak process for determining a blemish.
• Nafka Mina(s):
  • Whether a blemished bekhor can be slaughtered and eaten by the owner/Kohen, or if it must be left to die or buried.
  • The conditions under which an intentionally caused blemish permits slaughter versus prohibits it, and the associated knas (penalty).
  • Who is deemed credible to attest to the unintentional nature of a blemish, specifically distinguishing between Israelite and Kohen shepherds, and a Kohen testifying on his own bekhor versus another's.
  • The required beit din for certifying a blemish.

Text Snapshot

Mishnah Bekhorot 5:4-5 presents a series of halakhot concerning blemished kodashim and bekhorot. We will focus on the latter part, from the discussion of mum b'yedei adam onwards.

Mishnah Bekhorot 5:4-5 (Sefaria translation, with original text for nuance):

היה בכור רודפו, בעטו ועשה בו מום – ישחט עליו. If one’s firstborn offering was pursuing him, and he kicked the animal and caused a blemish in it, he may slaughter the animal on account of that blemish.

כל המומין הראויין לבא בידי אדם – רועים ישראל נאמנים, רועים כהנים אינן נאמנים. With regard to all the blemishes that are capable of being brought about by a person, Israelite shepherds are deemed credible to testify that the blemishes were not caused intentionally. But priest-shepherds are not deemed credible, as they are the beneficiaries if the firstborn is blemished.

רבן שמעון בן גמליאל אומר: נאמן הוא על של חבירו, ואינו נאמן על של עצמו. Rabban Shimon ben Gamliel says: A priest is deemed credible to testify about the firstborn of another, but is not deemed credible to testify about the firstborn belonging to him.

רבי מאיר אומר: החשוד על הדבר לא דן ולא מעיד. Rabbi Meir says: A priest who is suspect about the matter of causing a blemish may neither adjudicate nor testify in cases involving that matter, even on behalf of another.

כהן נאמן לומר: בכור זה הראיתי ומומו. A priest is deemed credible to say: I showed this firstborn animal to an expert and he ruled that it is blemished.

הכל נאמנים על מומי מעשר. Everyone is deemed credible to testify about the blemishes of an animal tithe offering.

בכור שנסמית עינו או שנקטעה ידו או שנשברה רגלו – נשחט על פי שלשה שיושבין בבית הכנסת. With regard to a firstborn animal whose eye was blinded or whose foreleg was severed or whose hind leg was broken, all of which obviously render the animal permanently blemished, that animal may be slaughtered on the basis of the ruling of three regular Jews who attend the synagogue…

רבי יוסי אומר: אפילו יש שם עשרים ושלשה – אינו נשחט אלא על פי מומחה. Rabbi Yosei disagrees and says: Even if there is a court of twenty-three Sages there, it may be slaughtered only on the basis of the ruling of an expert in judging blemishes.

Dikduk/Leshon Nuance:

• "כל המומין הראויין לבא בידי אדם": This phrase is crucial. It immediately flags a category of blemishes that are suspicious because they could be man-made. This is contrasted with mumim she'ein ra'uyin l'vo b'yedei adam (e.g., congenital deformities) where no suspicion of human intervention exists.
• "רועים ישראל נאמנים, רועים כהנים אינן נאמנים": The specific mention of "רועים" (shepherds) is central to the sugya. Is it the occupation that makes the difference, or merely their status as Kohen/Yisrael? This forms the basis of a significant kushya explored by Tosafot Yom Tov.
• "החשוד על הדבר לא דן ולא מעיד": R' Meir's sweeping statement establishes a general principle of Halakha regarding suspicion, which then needs to be reconciled with the more lenient views of Tanna Kamma and Rabban Shimon ben Gamliel.

Readings

Rambam, Perush HaMishnayot on Bekhorot 5:4:1

The Rambam's commentary on this Mishnah is foundational, offering clear sevarot for the differential treatment of Israelite and Kohen shepherds.

Text Snippet (Rambam on Mishnah Bekhorot 5:4:1):

היה בכור רודפו ובעטו ועשה בו מום הרי כו': כל המומין הראוין לבא בידי אדם רועים כו': כבר זכרנו שהכהנים חייבין בבכור בהמה טהורה כמו שאמר לא נפטרו מבכורות בהמה טהורה ואם יפול בו מום יאכלנו בעליו הכהן בטומאה כמו שיאכל בכור ישראל שנפל בו מום ואמר שאם היה זה הרועה ישראל ורועה בהמות כהן ואמר שהמום הזה אירע בלי כוונה הרי הוא נאמן לפי שלא יגיע לו תועלת שיעשה הוא המום וא"ת שאנו חוששין שמא יעשה זה כדי שיאכיל אותו ממנו הכהן כשישחט אותו מפני שמותר לישראל לאכול מבכור בעל מום כמו שזכרנו אין חוששין לזה לפי שהוא שיעור מועט ועל שיעור מועט כזה לא יעשה עון והוא ענין מה שאמר ללגימה לא חיישינן אבל אם היה הענין בהפך כמו שהיה הרועה כהן והבהמה של ישראל אינו נאמן הרועה לפי שבכור בעל מום מתנה לכהן כמו שזכרנו באורו והרועה חושב בדעתו שלא יניח אותו ויתנהו לזולתו מן הכהנים ולפיכך אנו חוששין שמא הוא עשה בו המום בכוונה ר"ל הרועה כדי שיאכלנו במומו וכן אינו מותר להעיד כהן אחר אם נפל מום בבכור דחיישינן לגומלין זה את זה ואמר רשב"ג נאמן הוא על של חבירו ואינו נאמן על של עצמו וחלק עליו ר"מ ואמר הואיל והוא חשוד אינו נאמן לא על של חבירו ולא על של עצמו וענין מחלוקת ר"מ ות"ק שר"מ אומר בכור כהן צריך ב' מן השוק להעיד עליו ות"ק אומר אינו מעיד כהן על בכור כהן הא שלא כהן מעיד ואפי' א' ורשב"ג אומר אפי' בני ביתו של כהן ובניו נאמנים אבל אשתו לא לפי שהיא כגופו והלכה כרשב"ג.

Translation:

"If a firstborn was pursuing him, he kicked it and caused a blemish thereby, behold it may be slaughtered upon it, etc." "All blemishes that are capable of being caused by a person, Israelite shepherds are credible, etc.": We have already mentioned that Kohanim are obligated concerning the firstborn of a pure animal, as it says, "they were not released from the firstborn of pure animals," and if a blemish falls upon it, its Kohen owner may eat it in a state of tum'ah, just as an Israelite eats a blemished firstborn. And it states that if this shepherd was an Israelite, tending the animals of a Kohen, and he said that this blemish occurred unintentionally, he is credible, for he does not derive benefit from causing the blemish. And if you say that we are concerned he might do this so that the Kohen would feed him from it when he slaughters it, because an Israelite is permitted to eat from a blemished firstborn, as we mentioned – we are not concerned about this, for it is a minimal amount, and for such a minimal amount, one would not commit a sin. This is the meaning of what was said, "we are not concerned about a mere 'sip' (ללגימה)." But if the matter was reversed, such that the shepherd was a Kohen, and the animal belonged to an Israelite, the shepherd is not credible, because a blemished firstborn is given as a gift to a Kohen, as we explained in its commentary. And the shepherd thinks in his mind that he will not abandon it and give it to another Kohen. Therefore, we are concerned that he caused the blemish intentionally – meaning the shepherd – so that he could eat it with its blemish. And similarly, a Kohen is not permitted to testify for another Kohen if a blemish fell on a firstborn, for we are concerned about gomalin (reciprocal benefit) between them. And Rabban Shimon ben Gamliel said, "He is credible concerning his friend's (firstborn), but not concerning his own." And Rabbi Meir disagreed with him and said, "Since he is suspected of the matter, he may neither adjudicate nor testify, neither for his friend nor for his own." And the meaning of the machloket between R' Meir and Tanna Kamma is that R' Meir says a Kohen's firstborn needs two witnesses from the market to testify about it, and Tanna Kamma says a Kohen does not testify about a Kohen's firstborn, but a non-Kohen testifies, even one. And Rabban Shimon ben Gamliel says even the Kohen's household members and his sons are credible, but not his wife, because she is like his own body. And the Halakha is according to Rabban Shimon ben Gamliel.

Rambam's Chiddushim:

1. The Sevara of Ne'emanut Based on Benefit: Rambam articulates the fundamental principle distinguishing the credibility of Israelite and Kohen shepherds. An Israelite shepherd, tending a Kohen's bekhor, is believed because he has no direct, significant benefit from the bekhor becoming blemished. The potential benefit of eating a small portion of meat is dismissed with the maxim "ללגימה לא חיישינן" (we are not concerned about a mere sip/minor benefit) and "אין אדם חוטא ולא לו" (a person does not sin without personal gain) - one would not commit a transgression for such a negligible gain. Conversely, a Kohen shepherd tending an Israelite's bekhor is suspected, because a blemished bekhor becomes a gift to the Kohen. The shepherd, being a Kohen himself, has a direct and significant personal interest in the animal becoming blemished, as he would then acquire it. This is a clear application of chashash g'neivah (suspicion of theft/misappropriation) where direct benefit exists.
2. The Principle of Gomalin and its Scope: Rambam extends the suspicion to a Kohen testifying on another Kohen's bekhor, introducing the concept of gomalin – the concern that they might reciprocate favors. This is a key point of friction with Rabban Shimon ben Gamliel.
3. The Machloket of R' Meir vs. Rabban Shimon ben Gamliel, and the Psak: Rambam delineates the machloket regarding the credibility of a Kohen. R' Meir holds that anyone חשוד על הדבר (suspect concerning the matter) is inherently disqualified from judging or testifying, even for others, due to a general lack of trustworthiness in that domain. Rabban Shimon ben Gamliel, however, limits the suspicion to one's own bekhor, allowing a Kohen to testify about another's. Rambam explicitly rules "והלכה כרשב"ג," asserting that the Halakha follows Rabban Shimon ben Gamliel. This ruling implies a more nuanced understanding of chashash than R' Meir's broad disqualification.

Tosafot Yom Tov, Bekhorot 5:4

Tosafot Yom Tov (T.Y.) provides crucial depth and analysis, often engaging with Rashi and the Gemara, and critically examining the Rambam's positions.

Text Snippet (T.Y. on Mishnah Bekhorot 5:4:1, "היה בכור רודפו"):

היה בכור . איל מנגח. רודפו לאדם לנגחו. ובעטו אדם לבכור ועשה בו מום ישחט עליו ואפי' כהן לפי שלהצלתו נתכוין. רש"י:

Translation:

"If a firstborn..." a butting ram. "Pursuing him" – meaning, pursuing a person to butt him. "And he kicked" – a person kicked the firstborn and caused a blemish in it, "he may slaughter it upon it," and even a Kohen (may do so), because he intended for his own salvation. Rashi.

T.Y.'s Chiddush 1 (on permissible mum b'yedei adam): T.Y. clarifies, by citing Rashi, that the Mishnah's case of the owner kicking a pursuing bekhor and causing a blemish, which permits slaughter, is specifically because "להצלתו נתכוין" (he intended for his own salvation). This is a vital distinction: not all mum b'yedei adam is forbidden. If the blemish is an unintended consequence of a permissible act (like self-defense), the knas of prohibiting slaughter on that blemish does not apply. This highlights the importance of kavanah (intention) in Halakha.

Text Snippet (T.Y. on Mishnah Bekhorot 5:4:4, "רועים כהנים אינן נאמנים"):

**רועים כהנים אינן נאמנים . פי' הר"ב רועים שהם כהנים. אינם נאמנים כשרועים בהמתן של ישראל וכו'. והוא הדין דכהן רועה אין נאמן להעיד על הבכור של כהן אחר דחיישינן לגומלין וכו'. וכן לשון רש"י. וצ"ע דמידי הוא טעמא אלא משום דחיישינן לגומלין וא"כ מאי איריא כהן רועה אפילו שאינו רועה נמי לא. וה"נ קאמרי להעיד על הבכור של כהן אחר. וא"כ אפי' שאינו רבו וכיון דאף על שאינו רבו לא יעיד אפילו שאינו רועה נמי. דהא לא שייך מימר אמר לא שביק רבי לדידי כו'. וה"נ כתב הר"ב לקמן בדבור ר' מאיר אומר כו' דלת"ק דוקא כהן אינו נאמן כו'. ולא אתני כהן רועה. ש"מ דס"ל דאפילו שאינו רועה נמי לא. ולישנא דגמ' וה"ה כהן לכהן דחיישינן לגומלין. ומיהו רש"י מפרש לקמן בהא דאיכא בין ר"מ לת"ק דלת"ק ב' כהנים שאינם רועים נאמנים. ושנים שהם רועים אינם נאמנים על של רבם. דלא חיישינן לגומלים אלא ברועים דקאי גביה וסבר אעיד את רבי והוא יעידני כשיתן לי ישראל בעלמא בכור. גם דברי הר"ב דלקמן בדעת הת"ק יש לפרש כך. ולפיכך יש לומר דדייק לכתוב כהן רועה לומר דאיכא בין רועה לאחר. דרועה אפילו שנים אינם נאמנים. ושאינם רועים כשהם שנים נאמנים. ודייק נמי לכתוב להעיד על הבכור של אחר לומר שכשאינו אלא אחד המעיד אפילו על אחר שאינו רבו נמי לא וממילא דאפילו אינו רועה נמי. דחשש דרועה ליתא אלא ברבו. כך נראה לי ליישב דבריו שבחכמת לשונו משמיענו. דהא דכהן לכהן איכא בתרי גווני. אי בדוקא רועה. וא"נ כשאינו רועה דאפילו לאחר לא. וסמך על המסקנא דרועה אפילו שנים לא וכשאינו רועה כשהוא אחד לא מהימן:

Translation:

"Kohen shepherds are not credible." The Rav (Rambam) explained: shepherds who are Kohanim are not credible when they tend the animals of Israelites, etc. And similarly, a Kohen shepherd is not credible to testify about the firstborn of another Kohen, for we are concerned about gomalin, etc. And this is also Rashi's language. But it is puzzling: is the reason not merely because we are concerned about gomalin? If so, why specifically a "Kohen shepherd"? Even a Kohen who is not a shepherd should not be credible. And similarly, they say to testify about the firstborn of another Kohen – so even if he is not his master. And since he would not testify even for someone who is not his master, then even if he is not a shepherd, he should not be credible. For it is not relevant to say, "My master will not leave it for me, etc." And similarly, the Rav wrote later, in the discussion of R' Meir's statement, "for Tanna Kamma, specifically a Kohen is not credible, etc." and it does not mention "Kohen shepherd." This implies that he (Rambam) holds that even a non-shepherd Kohen is not credible. And the language of the Gemara is, "and the same applies to a Kohen for a Kohen, for we are concerned about gomalin." However, Rashi explains later in the discussion of the difference between R' Meir and Tanna Kamma, that for Tanna Kamma, two non-shepherd Kohanim are credible. And two shepherds are not credible concerning their master's (animal). For we are only concerned about gomalin with shepherds who are constantly with him and think, "I will testify for my master, and he will testify for me when an Israelite gives me a firstborn elsewhere." The words of the Rav (Rambam) later, concerning the opinion of Tanna Kamma, can also be explained this way. Therefore, one can say that the Mishnah was precise in writing "Kohen shepherd" to indicate a difference between a shepherd and another (Kohen). For a shepherd, even two are not credible. And non-shepherds are credible if they are two. And it was also precise in writing "to testify about the firstborn of another" to imply that if there is only one witness, even for another (Kohen) who is not his master, he is not credible, and by extension, even if he is not a shepherd. For the concern of a shepherd only applies to his master. This is how it seems to me to reconcile his words, which he conveys with the wisdom of his language. For the case of a Kohen for a Kohen can be in two ways: either specifically a shepherd, or also when he is not a shepherd, even for another (Kohen). And he relied on the conclusion that a shepherd, even two, are not credible, and a non-shepherd, if he is one, is not credible.

T.Y.'s Chiddush 2 (Deconstructing "Kohen Shepherd" and Gomalin): T.Y. dives deep into the precise wording "רועים כהנים," questioning its necessity if the underlying concern is gomalin among all Kohanim. He notes that the Rambam himself, later, omits "רועה" when discussing R' Meir's view, implying a broader disqualification for any Kohen. T.Y. then brings Rashi's interpretation, which distinguishes between "shepherds" and "non-shepherds," and between one witness and two. According to Rashi, gomalin is a concern particularly for shepherds because of their close relationship and constant interaction with their master's animals, making the reciprocal intent more concrete ("I will testify for my master, and he will testify for me"). Non-shepherd Kohanim, if they are two, might be believed. T.Y. meticulously attempts to reconcile these views, suggesting that the Mishnah's language is highly precise, indicating that the degree of suspicion and the application of gomalin depend on the specific context (shepherd vs. non-shepherd, one vs. two witnesses, master's vs. another's animal). This intricate analysis demonstrates the lomdus of discerning the precise scope of a halakhic principle.

Text Snippet (T.Y. on Mishnah Bekhorot 5:4:5, "רבן שמעון בן גמליאל אומר נאמן הוא כו'"):

רבן שמעון בן גמליאל אומר נאמן הוא כו' . כתב הר"ב בין רבו בין אחר לא נחשדו עליו. ופסק נמי הלכה כרשב"ג. ולא קשי' אהלכתא דספ"ד דדמאי החמרים שנכנסים לעיר אמר אחד שלי חדש ושל חברי ישן כו' דחיישינן לגומלין. התם ששניהם לפנינו ובידיהם למכור איכא חששא דגומלין משא"כ הכא דלמיחש דמעיד עכשיו כדי שיגמול לו לאחר זמן כשיבא לידו בכור ויטיל בו מום ולחשש גומלין כי הא לא חיישינן. וכ"ש לפירש"י שכתבתי במ"ח פ"ב דכתובות דההיא דדמאי בשכלי אומנותו בידו דמוכח דבא למכור. ולא להצניע. ולכך חייש לגומלים. והיינו כדפרישית דמשום שעכשיו גם הוא בא למכור הוא דאיכא חששא. הא לאו הכי לא. ולפי מה שאכתוב לקמן דלא פסק הר"ב הלכה כרשב"ג אלא הכא בבכור דוקא. מעיקרא לא קשיא הלכתא אהלכתא כלל:

Translation:

"Rabban Shimon ben Gamliel says, 'He is credible,' etc." The Rav (Rambam) wrote: "Neither his master nor another is suspected concerning him." And he also ruled Halakha k'Rabban Shimon ben Gamliel. And it is not difficult regarding the Halakha in the end of chapter 4 of Demai, concerning the donkey drivers who entered the city, where one said, "Mine is new, and my friend's is old," etc., where we are concerned about gomalin. There, since both are before us and have it in their hands to sell, there is a concern of gomalin. This is not the case here, where to be concerned that he testifies now so that he will reciprocate later when a firstborn comes into his hand and he causes a blemish in it – for such a concern of gomalin, we are not concerned. And certainly, according to Rashi's explanation that I wrote in Mishnah 8, chapter 2 of Ketubot, that the case of Demai refers to someone whose craft is in his hand, which proves that he came to sell, not to store away. And therefore, he was concerned about gomalin. And that is as I explained, that it is because he also came to sell now that there is a concern. Otherwise, not. And according to what I will write later, that the Rav did not rule Halakha k'Rabban Shimon ben Gamliel except specifically here regarding a firstborn, then from the outset, there is no difficulty between the Halakhot at all.

T.Y.'s Chiddush 3 (Reconciling Gomalin with R. Shimon ben Gamliel's Psak): T.Y. addresses a crucial potential contradiction: Rambam rules Halakha k'Rabban Shimon ben Gamliel (Kohen is credible on another's bekhor), yet there's a principle of gomalin that often disqualifies witnesses in cases of reciprocal benefit (e.g., Demai 4:7). T.Y. distinguishes between immediate, tangible reciprocal benefit (as in Demai, where both parties are present and actively involved in selling) and a remote, speculative future benefit (testifying now hoping for a favor later). The latter, he argues, is too tenuous to trigger the gomalin disqualification. This refinement of the gomalin principle is significant. Crucially, T.Y. hints at an even deeper reconciliation, suggesting that Rambam's psak for Rabban Shimon ben Gamliel might be specific to bekhorot, not a general rule. This sets the stage for his subsequent analysis.

Text Snippet (T.Y. on Mishnah Bekhorot 5:4:7, "רבי מאיר אומר החשוד על הדבר"):

**רבי מאיר אומר החשוד על הדבר . דהיינו כהנים שנחשדו על הבכורות רש"י בגמ' [דף ל"ה]. ומסיים הטור ר"ס שי"ד מפני שיש להם בו טורח גדול לטפל בו עד שימות: לא דנו ולא מעידו . כתב הר"ב ואיכא בין ר"מ לת"ק דלר"מ בכור כהן שנפל בו מום צריך שנים מן השוק להעיד עליו ועד אחד אפי' שאין כהן אין מועיל בו. ותמיהני דהא לא אמר ר"מ אלא החשוד. ובגמ' איכא בינייהו דר' יהושע בן קפוסאי דתניא ריב"ק אומר בכור ביד כהן צריך שנים מן השוק להעיד עליו. ופירש"י צריך שנים מן השוק שנים כל שהן ואפי' כהנים. אבל כהנים שבביתו לא. ת"ק אית לי' דריב"ק דאמר ת"ק (רועי)[כהנים] דעלמא נאמנים. ואפי' אבכורות דכהנים ולא חיישינן לגומלים אלא ברועה דקאי גביה וסבר אעיד את רבי והוא יעידני כשיתן לי ישראל בעלמא בכור. ור"מ לית לי' לר"י [ב"ק] לגמרי דכיון שנחשדו כהנים על הבכור לא דן ולא מעיד אפי' כהן דשוק ואפי' בכור ביד ישראל. ע"כ. וכ"כ התוס' דת"ק סבר כר"י [ב"ק] ושנים מן השוק דקאמר ר"י [ב"ק] בכהנים איירי דישראל אפי' חד מהימן ולר"מ כל היכא (דאסור) [דחשיד] אפילו שנים אין נאמנים. ע"כ. ומ"ש הר"ב ולת"ק דוקא כהן אין נאמן וכו' ולעיל כתב כהן רועה. ושם הארכתי. ומ"ש הר"ב והלכה כרשב"ג. גמרא. וא"כ בס"פ דלעיל דסתם לן כל החשוד על הדבר לא דנו ולא מעידו אינה הלכה. וכן מצאתי שם בנא"י בפי' הרמב"ם שכתב עליו דהוא דעת ר"מ. והוא דחוי כי העיקר הוא אין אדם חוטא ולא לו. ולפיכך החשוד על דבר דנו ומעידו. ע"כ. וכן בחבורו פסק דבכל דבר החשוד מעיד. כמ"ש בפי"ב מהלכות מעשר ובפ"ח משמטה וספ"י מה' משכב ומושב ובפי"א מהלכות עדות. אבל יראה לי שהר"ב שלא דחאה מהלכה לא מפני שנמשך אחר הנוסח שבידינו מפירוש הרמב"ם שלא נזכר בה כלום ונמשך הוא אחריו והניח הדבר סתום וסמך אדהכא. אלא נ"ל שסובר שהיא הלכה פסוקה. ולא פסק בכאן כרשב"ג. שיהא כן ההלכה בכל מקום. אלא דוקא הכא בבכור. וכדעת הראב"ד בהשגותיו ספי"ב מהלכות מעשר שכתב ואם קבעו הלכה כרשב"ג לענין מטיל מום בבכור שהוא קנס [כלומר מה שאינו נאכל עליו כדלעיל מ"ג] אבל לשאר איסורין חשוד אין מעיד וסתם לן תנא בבכורות [ספ"ד] כר"מ. וה"נ במשנה ו' פ"ד דדמאי לא האמינו לאומר איש פלוני נאמן אלא משום קל שהקילו באכסניא. ע"כ. וכ"כ הר"ב שם קל הוא כו' שמעינן מינה דאל"ה אין החשוד מעיד על אחר. וה"נ מוכח שם בראש הפרק דבשבת אוכל על פיו וחשכה מוצאי שבת לא יאכל עד שיעשר. והב"י בטי"ד סימן קי"ט מקשה אמתני' זו דחשכה מ"ש לא יאכל. והא החשוד נאמן על של אחרים [כלומר להרמב"ם שפוסק כרשב"ג בכל דבר] ואין לומר דההיא מתני' אתיא כר"מ ולא קי"ל כותיה. שהרי הרמב"ם עצמו פסקה בריש פי"ב מהלכות מעשר. עכ"ד. אבל מההיא מ"ו דאמרו טעמא דלא האמינו לאומר איש פלוני נאמן. אלא משום קל הוא כו' לא קשיא שכבר תי' זה בכ"מ משום דבעינן לאוקמי למתני' אפי' כר"מ. דהא סתמא מתניא ע"כ. וז"ל הרמב"ם [שם] בפירושה העיקר אצלינו אין אדם חוטא ולא לו. ולפיכך [ודאי] לא ישלחו לאיש שאינו נאמן. מפני שאין לו הנאה בזה הנאה קרובה מיד. וכל זה כדי להקל עליו. מפני שהוא גר ואינו מכיר אנשי המדינה. עכ"ל. הנה סמכה על העיקר הזה שאין אדם חוטא ולא לו. שהוא דלא כר"מ כמ"ש בשמו ומש"ה דחוק הל' דמסיים בו וכל זה כדי להקל כו'. ואינו סובל לומר בה מה שמיישב הכ"מ בגמ' שאמרו הטעם כדי לאוקמה אף לר"מ:

Translation:

"Rabbi Meir says, 'He who is suspect concerning the matter'." This refers to Kohanim who are suspected concerning firstborns, Rashi in the Gemara [daf 35]. And the Tur siman 614 concludes, "because they have great burden in tending to it until it dies." "May neither adjudicate nor testify." The Rav (Rambam) wrote that there is a difference between R' Meir and Tanna Kamma, that according to R' Meir, a Kohen's firstborn that developed a blemish requires two witnesses from the market to testify about it, and even one non-Kohen witness is not effective. And I am puzzled, for R' Meir only stated "he who is suspect." And in the Gemara, there is a difference between them (R' Meir and Tanna Kamma) regarding R' Yehoshua ben Kapsai, as it is taught, R' Yehoshua ben Kapsai says: "A firstborn in the hand of a Kohen requires two from the market to testify about it." And Rashi explained: "two from the market" means any two, even Kohanim, but not Kohanim from his household. Tanna Kamma agrees with R' Yehoshua ben Kapsai, as Tanna Kamma says that Kohanim in general are credible, even concerning Kohanim's firstborns, and we are not concerned about gomalin except for a shepherd who is with him and thinks, "I will testify for my master, and he will testify for me when an Israelite gives me a firstborn elsewhere." And R' Meir does not accept R' Yehoshua ben Kapsai at all, for since Kohanim are suspected concerning firstborns, he may neither judge nor testify, not even a Kohen from the market, and not even concerning a firstborn in the hand of an Israelite. So far. And the Tosafot also wrote that Tanna Kamma holds like R' Yehoshua ben Kapsai, and "two from the market" that R' Yehoshua ben Kapsai refers to Kohanim, but an Israelite, even one, is credible. And according to R' Meir, wherever there is suspicion, even two are not credible. So far. And what the Rav wrote, "and for Tanna Kamma, specifically a Kohen is not credible, etc." and earlier he wrote "Kohen shepherd," and there I elaborated. And what the Rav wrote, "and the Halakha is according to Rabban Shimon ben Gamliel," from the Gemara. If so, then in the end of the previous chapter, where it states generally, "anyone suspect concerning a matter may neither judge nor testify," is not the Halakha. And I found there in the Na"Y (Novellae of R. Yehudah Ayash) in the commentary of the Rambam that he wrote about it that it is R' Meir's opinion, and it is rejected because the principle is "a person does not sin without personal gain." Therefore, one who is suspect concerning a matter may judge and testify. So far. And similarly, in his magnum opus (Mishneh Torah), he ruled that in every matter, one who is suspect may testify, as he wrote in chapter 12 of Hilkhot Ma'aser, and chapter 8 of Shemitah, and chapter 10 of Hilkhot Mishkav u'Moshav, and chapter 11 of Hilkhot Edut. But it seems to me that the Rav (Rambam) did not reject it from Halakha not because he followed the version of the Rambam's commentary we have, which mentions nothing of it and he followed it and left the matter ambiguous and relied on this. Rather, it seems to me that he holds it is a psukah Halakha (established law). And he did not rule here according to Rabban Shimon ben Gamliel so that this would be the Halakha everywhere, but specifically here concerning a firstborn. And this is like the opinion of the Ra'avad in his glosses to chapter 12 of Hilkhot Ma'aser, who wrote: "And if they established Halakha k'Rabban Shimon ben Gamliel concerning one who causes a blemish in a firstborn, which is a penalty [meaning, that it may not be eaten on account of it, as in Mishnah 3 above], but for other prohibitions, one who is suspect does not testify. And the Tanna in Bekhorot [end of chapter 4] presents R' Meir's view anonymously (as a stam Mishnah)." And similarly, in Mishnah 6, chapter 4 of Demai, they did not believe one who said, "so-and-so is credible," except because it was a leniency they made for guests. So far. And the Rav (Rambam) also wrote there, "it is a leniency," etc., from which we learn that otherwise, one who is suspect does not testify for another. And this is also proven there at the beginning of the chapter that on Shabbat, one may eat based on his word, but when Shabbat ends, he may not eat until he tithes. And the Beit Yosef in Yoreh De'ah Siman 119 questions this Mishnah of "when Shabbat ends, he may not eat." For is not one who is suspect credible concerning others' (produce) [meaning, according to Rambam who rules Halakha k'Rabban Shimon ben Gamliel in everything]? And one cannot say that that Mishnah follows R' Meir and we do not hold like him. For Rambam himself ruled it at the beginning of chapter 12 of Hilkhot Ma'aser. So far. But from that Mishnah 6, where they said the reason they did not believe one who said "so-and-so is credible" was "only because it is a leniency," etc., there is no difficulty, for this has already been answered in many places that we need to explain the Mishnah even according to R' Meir, for it is taught anonymously. So far. And this is the language of the Rambam [there] in its commentary: "The principle with us is, 'a person does not sin without personal gain.' And therefore, [certainly] they would not send to a person who is not credible, because he has no immediate, close benefit in this. And all this is to be lenient with him, because he is a stranger and does not know the people of the country." So far. Behold, it relies on this principle that "a person does not sin without personal gain," which is not like R' Meir, as he wrote in his name. And therefore, it is difficult with the Halakha he concludes with, "and all this is to be lenient," etc. And it cannot bear what the Kesef Mishneh reconciles in the Gemara, that they said the reason was to establish it even according to R' Meir.

T.Y.'s Chiddush 4 (Rambam's Psak & the Scope of Chashud al haDavar): T.Y. identifies a profound tension: Rambam rules Halakha k'Rabban Shimon ben Gamliel (Kohen is believed on another's bekhor), yet this seems to directly contradict a broader principle, often attributed to R' Meir, that "החשוד על הדבר לא דן ולא מעיד" (one suspect in a matter may neither judge nor testify), which Rambam himself often seems to endorse in Mishneh Torah. T.Y. cites the Na"Y and Kesef Mishneh to show the Rambam's consistent reliance on ein adam choteh v'lo lo as a general principle to allow the testimony of the suspect. However, T.Y. then introduces the Ra'avad's perspective: the psak for Rabban Shimon ben Gamliel is specific to bekhorot, as the intentional blemish in a bekhor incurs a knas (penalty) rather than a simple prohibition. For other issurim, R' Meir's stricter rule of Chashud al haDavar (disqualification of the suspect) might still apply, particularly when the Mishna is stam (anonymous), implying it follows R' Meir. This nuanced reading resolves the apparent contradiction in Rambam's psak by circumscribing the scope of Rabban Shimon ben Gamliel's ruling, making it an exception rather than a universal rule. T.Y. demonstrates a sophisticated understanding of psak heuristics, distinguishing between general principles and domain-specific rulings.

Friction

Kushya 1: The Specificity of "רועים כהנים" and the Scope of Gomalin

The Mishnah states, "רועים כהנים אינן נאמנים" (Kohen shepherds are not credible). Both Rambam and Rashi explain this lack of credibility due to the Kohen's potential benefit from the bekhor becoming blemished (as it then becomes his possession) or the concern of gomalin (reciprocal favors) when testifying for another Kohen. However, Tosafot Yom Tov (Bekhorot 5:4:4) raises a pointed kushya: If the core issue is gomalin (mutual benefit) or the Kohen's personal gain, why does the Mishnah specifically mention "רועים" (shepherds)? Is the act of shepherding intrinsically linked to the suspicion? If gomalin is the underlying sevara, then any Kohen testifying for any other Kohen should be suspect, regardless of whether they are shepherds or not. The Rambam himself, T.Y. notes, later discusses R' Meir's view of "Kohen" generally, without the "shepherd" qualification. This suggests the "shepherd" aspect might be superfluous or, at least, not the sole determinant of credibility. Why the specific terminology, if the principle is broader?

Terutz: Tosafot Yom Tov, engaging with Rashi's interpretation, offers a nuanced resolution. The specificity of "רועים" is indeed critical, as it signifies a heightened level of suspicion and a more direct, concrete concern for gomalin. Rashi (as interpreted by T.Y.) distinguishes between different categories:

1. Two Kohen Shepherds: These are not credible even for their master's bekhorim. The close, ongoing relationship ("דקאי גביה") and direct access to the animals make the concern of gomalin very potent. A shepherd might think, "I will testify for my master now, and he will testify for me when I receive a bekhor from an Israelite." This is an immediate and tangible form of reciprocal intent.
2. Two Kohen Non-Shepherds: These are credible according to Tanna Kamma. While they are Kohanim, their lack of direct involvement with the animals and the absence of a constant, mutually beneficial professional relationship diminishes the gomalin concern to a point where their testimony is accepted.
3. One Kohen (Shepherd or Non-Shepherd): Even for another Kohen, a single Kohen witness is not credible. This implies that while the gomalin concern might be less direct for non-shepherds, a single Kohen's testimony is still insufficient, perhaps due to the general, albeit less direct, interest a Kohen has in the bekhor halakha.

Thus, the term "רועים" in the Mishnah is not superfluous but rather a precise qualifier. It points to the specific context where the gomalin concern is strong enough to disqualify even two witnesses due to their intimate professional connection and the immediacy of potential reciprocal benefit. For other Kohanim, the gomalin concern is either weaker or requires a different evidentiary standard (e.g., two witnesses instead of one). This rigorous parsing of the Mishnah's language allows for a more finely tuned application of the halakhic principle, distinguishing between varying degrees of chashash.

Kushya 2: Rambam's Conflicting Rulings on Chashud al haDavar

The Mishnah presents Rabbi Meir's view: "החשוד על הדבר לא דן ולא מעיד" (one who is suspect concerning a matter may neither adjudicate nor testify). This appears to be a broad, general principle disqualifying any individual suspected of a particular transgression from matters related to that transgression. However, the Rambam, in his Perush HaMishnayot (Bekhorot 5:4:1), explicitly rules "והלכה כרשב"ג" (the Halakha is according to Rabban Shimon ben Gamliel), who states that a Kohen is credible to testify about another's bekhor. This stands in direct contrast to R' Meir's stricter view.

Tosafot Yom Tov (Bekhorot 5:4:7) highlights this tension, pointing out that Rambam elsewhere in Mishneh Torah (e.g., Hilkhot Ma'aser 12, Hilkhot Edut 11) seems to follow a more lenient approach, generally accepting the testimony of someone "suspect" if there's no direct, immediate benefit, based on the principle of "אין אדם חוטא ולא לו" (a person does not sin without personal gain). This creates a kushya: How can Rambam simultaneously rule Halakha k'Rabban Shimon ben Gamliel (allowing Kohen testimony for another's bekhor), which rejects R' Meir's broad disqualification, while also appearing to uphold similar principles of chashash in other contexts, sometimes even citing R' Meir's view as stam (anonymous Mishnah, which is generally Halakha)? Is the Rambam inconsistent, or is there a deeper principle at play?

Terutz: The reconciliation, as advanced by Tosafot Yom Tov citing the Ra'avad (Hasagot to Hilkhot Ma'aser 12:1), lies in understanding the specific nature of the issur and the associated knas in the context of bekhorot.

1. Nature of Mum b'Yedei Adam in Bekhorot: In the case of a bekhor, if a blemish is caused intentionally (mum b'yedei adam b'kavanah), the animal cannot be slaughtered on account of that blemish. This is a knas (penalty). The animal is not automatically rendered mutar (permitted) for consumption; rather, it remains assur until another, unrelated, unintentional blemish develops. This is a severe penalty designed to deter intentional blemishing.
2. Distinction Between Knas and Issur: The Ra'avad argues that the leniency of Rabban Shimon ben Gamliel (and by extension, the Rambam's adoption of it) applies specifically to the case of causing a blemish in a bekhor because the consequence is a knas, not a straightforward issur that would render the animal muttar immediately. Since the person causing the blemish does not gain immediate, direct access to the animal by doing so (they still have to wait for another blemish), the "אין אדם חוטא ולא לו" principle holds greater sway. The motivation for illicit gain is significantly reduced.
3. General Chashud al haDavar: For other prohibitions where the intentional act directly leads to an immediate, tangible benefit or the removal of an issur without further impediment, the principle of Chashud al haDavar (as articulated by R' Meir, and sometimes presented as stam in Mishnaic contexts) might still apply, disqualifying the suspect from testifying. In these cases, the chashash of personal gain is direct and immediate, justifying the stricter approach.

Therefore, Rambam's psak of Halakha k'Rabban Shimon ben Gamliel is not a universal rejection of R' Meir's principle of Chashud al haDavar. Instead, it is a context-specific ruling, acknowledging the unique halakhic structure of mum b'yedei adam in bekhorot as incurring a knas, which sufficiently mitigates the suspicion of immediate personal gain, allowing for a more lenient standard of ne'emanut. This sophisticated distinction allows Rambam to maintain consistency across his oeuvre by applying principles according to the specific halakhic and ethical landscape of each sugya.

Intertext

Tanakh: The Sanctity and Laws of the Firstborn

The mitzvah of Bekhor is rooted in the Torah, emphasizing its sanctity and special status.

• Devarim 15:19-20: "כָּל-הַבְּכוֹר אֲשֶׁר יִוָּלֵד בִּבְקָרְךָ וּבְצֹאנְךָ הַזָּכָר תַּקְדִּישׁ לַיהוָה אֱלֹהֶיךָ לֹא תַעֲבֹד בִּבְכוֹר שׁוֹרֶךָ וְלֹא תָגֹז בְּכוֹר צֹאנֶךָ. בִּפְנֵי יְהוָה אֱלֹהֶיךָ תֹאכְלֶנּוּ שָׁנָה בְשָׁנָה בַּמָּקוֹם אֲשֶׁר-יִבְחַר יְהוָה אַתָּה וּבֵיתֶךָ." (Every firstborn male that is born to your herd and your flock, you shall consecrate to the Lord your God. You shall not work with the firstborn of your ox nor shear the firstborn of your flock. You shall eat it before the Lord your God year by year in the place that the Lord chooses, you and your household.)
  • This passage establishes the kedushah (sanctity) of the bekhor and the prohibition against deriving ordinary benefit from it (working, shearing). It is designated for consumption b'kedushah. The Mishnah's discussion of mumim and hatzalah relates directly to how this mitzvah is fulfilled when the animal becomes unfit for sacrifice but is still kadosh. The very existence of a mechanism to permit a blemished bekhor for consumption reflects a balance between its inherent sanctity and the practical need to avoid loss, especially for the Kohen.
• Malachi 1:8: "וְכִי-תַגִּשׁוּן עִוֶּר לִזְבֹּחַ אֵין רָע וְכִי תַגִּישׁוּ פִּסֵּחַ וְחֹלֶה אֵין רָע קָרְבֵהוּ נָא לְפֶחָתֶךָ הֲיִרְצְךָ אוֹ הֲיִשָּׂא פָנֶיךָ אָמַר יְהוָה צְבָאוֹת." (When you bring a blind animal for sacrifice, it is no evil; and when you bring a lame or sick animal, it is no evil! Present it now to your governor; will he be pleased with you or show you favor? says the Lord of Hosts.)
  • This pasuk from Malachi strongly condemns offering blemished animals as sacrifices, highlighting the ideal of offering only unblemished korbanot. While the Mishnah addresses bekhorot that become blemished, the underlying disdain for blemished offerings in the Temple context informs the gravity with which mum b'yedei adam is treated. Causing a blemish, even if it eventually permits consumption by a Kohen, violates the spirit of offering t'mimim (whole, unblemished animals) to God. The knas imposed on intentional blemishing reflects this moral gravity.

Shulchan Aruch: Bekhor Laws and Ne'emanut

The principles discussed in our Mishnah are codified in Halakha, particularly in Yoreh De'ah.

• Shulchan Aruch, Yoreh De'ah 319:1-2 (Laws of Bekhor):
  • YD 319:1: "בכור שנפל בו מום, בין בכור ישראל בין בכור כהן, אסור להטיל בו מום בידים אפילו מום קבוע, אלא אם כן המום בא מאליו. אבל אם הטיל בו מום בידים, אסור לשוחטו על אותו מום, אלא מניחו עד שיפול בו מום אחר מאליו, ואז שוחטו על המום האחר. ואם שחטו על אותו מום שהטיל בו בידים, הרי זה אסור באכילה וההורג חייב מיתה בידי שמים, ובזה אין חילוק בין ישראל לכהן." (A firstborn that developed a blemish, whether an Israelite's firstborn or a Kohen's firstborn, it is forbidden to intentionally cause a blemish with one's hands, even a permanent blemish, unless the blemish came on its own. But if one intentionally caused a blemish with one's hands, it is forbidden to slaughter it on account of that blemish; rather, one must leave it until another blemish develops on its own, and then slaughter it on account of that other blemish. And if one slaughtered it on account of the blemish he intentionally caused, it is forbidden to eat, and the one who slaughtered it is liable to death by the hand of Heaven, and in this, there is no difference between an Israelite and a Kohen.)
    • This ruling directly reflects the Mishnah's principle of mum b'yedei adam and the knas associated with it. The prohibition of intentional blemishing and the requirement to wait for a new blemish before slaughtering is central. The penalty of issur (prohibition) and misah b'yedei Shamayim (death by heavenly decree) for violating this knas underscore the seriousness of the transgression.
  • YD 319:2: "כל המומין הראויים לבא בידי אדם, רועים ישראל נאמנים להעיד שלא הטילו בו מום, ורועים כהנים אינם נאמנים. ואם העיד ישראל אחד שבא המום מאליו, נאמן. כהן אחד נאמן לומר שהראה בכור זה למומחה והוא ממום." (Regarding all blemishes that are capable of being caused by a person, Israelite shepherds are credible to testify that they did not cause the blemish, but Kohen shepherds are not credible. And if one Israelite testified that the blemish came on its own, he is credible. One Kohen is credible to say that he showed this firstborn to an expert and it is blemished.)
    • This section directly codifies the ne'emanut distinctions from our Mishnah. It distinguishes between Israelite and Kohen shepherds, validating the Israelite's testimony due to lack of direct benefit. The final sentence, allowing a single Kohen to attest to having shown the bekhor to an expert, reflects the nuanced credibility given to Kohanim in specific contexts, aligning with Rabban Shimon ben Gamliel's view (as per Rambam's psak) and the principle of ein adam choteh v'lo lo.

These intertexts demonstrate the enduring relevance and practical application of the Mishnaic sugya, showcasing how its intricate legal distinctions are grounded in broader theological principles and meticulously codified into subsequent halakhic works.

Psak/Practice

The sugya provides several crucial halakhic heuristics and practical rulings:

1. Intentional vs. Unintentional Blemish: The fundamental principle is that mum b'yedei adam b'kavanah (an intentionally caused blemish) is forbidden and incurs a knas. The animal cannot be slaughtered on that specific blemish. One must wait for another, naturally occurring blemish (Mishnah 5:4, S.A. YD 319:1). However, if the blemish is caused unintentionally or as a byproduct of a permissible act (like self-defense, as in "היה בכור רודפו"), it is permitted to slaughter on that blemish. This emphasizes kavanah (intent) as a pivotal factor in determining the halakhic outcome.
2. Credibility (Ne'emanut) for Blemishes:
   • Israelite vs. Kohen Shepherds: Israelite shepherds are generally credible regarding blemishes on bekhorot they tend, due to minimal personal benefit ("ללגימה לא חיישינן"). Kohen shepherds, however, are not credible when tending Israelite bekhorot (which would become their property if blemished) due to direct personal interest. This is a meta-psak heuristic regarding suspicion and self-interest.
   • Kohen on Another's Bekhor: The Halakha follows Rabban Shimon ben Gamliel (as per Rambam's psak): a Kohen is credible to testify about a blemish on another Kohen's bekhor. This is because the concern of gomalin (reciprocal favors) is deemed too remote in this specific context, especially given the knas nature of the issur rather than a direct enablement of consumption.
   • Kohen on His Own Bekhor: A Kohen is not credible concerning his own bekhor, reflecting the strong chashash of direct self-interest.
   • "I showed this bekhor": A Kohen is credible to state that he showed his bekhor to an expert and that it was ruled blemished. This is not testifying about the blemish itself, but about a procedural step, where the expert's judgment is the primary determinant.
   • Animal Tithe: Everyone is credible regarding blemishes on an animal tithe (ma'aser behemah), as the owner's benefit is less direct and the kedushah is lighter than a bekhor.
3. Certification of Blemishes: For obvious, severe blemishes, a panel of three laymen from the synagogue can certify the blemish. For less obvious or more complex blemishes, an expert (mumcheh) is required, according to Rabbi Yosei, whose opinion is often favored for stricter application in dinim d'orayta. This highlights the role of expertise and communal validation in halakhic processes.
4. Consequences of Uncertified Slaughter: If a bekhor is slaughtered without proper certification of a blemish, the meat is prohibited. Buyers must be refunded, and uneaten meat must be buried. This severe penalty underscores the importance of adhering to the halakhic process for hittir (permitting) kodashim.

In contemporary Halakha, with the absence of the Beit HaMikdash and the cessation of bekhor sacrifices, the practical application of these laws primarily centers on the bekhor animals born in Israel. While korban laws are not in effect, the special kedushah of the bekhor remains. Thus, bekhorot are generally kept until they develop a natural, permanent blemish, then certified by a rabbinic expert, and subsequently shechted and consumed by Kohanim or sold to them. The nuances of mum b'yedei adam and ne'emanut still guide the determination of whether a blemish qualifies the animal for slaughter.

Takeaway

This sugya meticulously dissects the interplay of human intent, personal benefit, and public trust within the sacred context of kodashim. It teaches us that Halakha is not monolithic in its application of suspicion, but rather finely tunes its demands for credibility based on the nature of the transgression, the immediate gain involved, and the specific communal roles of those testifying.
