Mishnah Bekhorot 6:8-9

StandardExpert – Beit Midrash AnalysisDecember 19, 2025

Sugya Map

The Mishnah in Bekhorot 6:8-9 delineates an extensive catalogue of mumin (blemishes) that permit the slaughter of a bechor (firstborn animal) outside the Temple confines, and, by extension, allow for the redemption of other consecrated animals (קודשים) bearing these same mumin. This sugya sits at the nexus of several core halakhic principles concerning the sanctity and usability of sacrificial animals.

Core Issue

The central inquiry revolves around defining what constitutes a "blemish" (mum) sufficient to render a bechor unfit for offering on the mizbe'ach (altar), thereby re-classifying it as hullin (non-sacred) for consumption purposes, albeit with specific restrictions. The Mishnah provides a detailed, anatomical, and sometimes quantitative, taxonomy of such mumin across various bodily parts: ears, eyes, nose, lips, gums, genitals, tail, legs, and even general physiological anomalies.

Nafka Mina

The practical ramifications (nafka mina) are manifold:

  1. Slaughter Location: A bechor without a mum must be offered in the Temple and eaten by kohanim in Jerusalem. A bechor with a mum may be slaughtered anywhere in Eretz Yisrael and consumed by anyone, provided the kohanim have been given their due portions (the matnot kehunah). This distinction impacts economic activity, local religious practice, and the kohanim's livelihood.
  2. Redemption of Kodshim: The criteria for mumin in a bechor serve as the standard for redeeming kodshim that have become disqualified. If a kodshim animal develops one of these mumin, it can be redeemed for money, and the money is then used for another korban or for Temple maintenance, while the blemished animal becomes hullin1.
  3. Nature of Mum: The Mishnah distinguishes between mumin that are kavua (permanent) and over (temporary), or nigleh (visible) versus nistar (concealed). Only permanent, visible mumin permit slaughter/redemption. This requires careful examination and, at times, waiting periods or specific tests, as seen with "constant tears" or "pale spots"2.
  4. Authority of Expert: The Mishnah highlights the role of experts (mumchim) in identifying mumin, particularly Ila, and the subsequent beit din that ratified his additions, underscoring the dynamic nature of halakhic development and the reliance on specialized knowledge3.

Dikduk / Leshon Nuance:

  • "נשבר עצם ידו ועצם רגלו, אף על פי שאינו כו'" (Mishnah 6:8): The omission of the concluding word "ניכר" (noticeable) in the Mishnah, despite being clearly implied and completed by the Gemara and Rishonim, is noteworthy. It suggests a common understanding that such a blemish is not always obvious, and the subsequent discussion aims to define the threshold of "noticeability."
  • "מומין אלו מנה אילא ביבנה" (Mishnah 6:8): The phrasing "מומין אלו" (these blemishes) can be read two ways: either referring to all blemishes listed in the chapter up to this point, or specifically to the immediately preceding ones. This ambiguity is addressed by Rishonim like Rashash.
  • "לא שמענו אלו" vs. "לא שמענו אלא אלו" (Mishnah 6:8): The textual variant pointed out by Tosafot Yom Tov on Ila's additions is critical. "לא שמענו אלו" means "we did not hear these (specific ones)," implying lack of tradition. "לא שמענו אלא אלו" means "we only heard these (and no others like them)," which implies a limitation rather than a lack of knowledge. The former supports the Beit Din's eventual acceptance, as lack of knowledge is not a refutation.
  • "שאין לו בית אשכים, או שאין לו אלא אחד" (Mishnah 6:8): The Mishnah carefully distinguishes between the bayit ashakhim (scrotal sac) and the eshekh (testicle) itself, which becomes central to the debate between R' Yishmael and R' Akiva regarding how to ascertain the presence of testicles.
  • "אינו בכור לגזוז ולעבוד" (Mishnah 6:9): The Rabbanan's ruling regarding the tumtum and androgynus is profound. It's not merely that they are mumim that disqualify from the mizbe'ach, but rather that their very status as "firstborn" is denied, removing them from the category of kodshim altogether. This allows them to be shorn and worked, a status typically reserved for hullin or ma'aser beheimah which has been redeemed. This is a fundamental re-categorization based on uncertain gender.

Readings

The Mishnah in Bekhorot 6:8-9 presents a rich tapestry of halakhot and machlokot, drawing attention to the meticulous nature of Chazal's definitions of mumin. We'll delve into a few key interpretations from Rishonim and Acharonim, highlighting their unique contributions.

1. Rambam: The Threshold of Visibility for a Broken Bone

The Mishnah states, "נשבר עצם ידו ועצם רגלו, אף על פי שאינו כו'" (Mishnah Bekhorot 6:8), implying that a broken bone is a mum even if it's not immediately obvious. The Gemara (Bekhorot 38b) completes this phrase as "אף על פי שאינו ניכר" (even if it is not noticeable). The Rambam, in his commentary to the Mishnah, provides a precise definition for this "lack of noticeability":

רמב"ם על משנה בכורות 6:8:1: "נשבר עצם ידו ועצם רגלו אע"פ שאינו כו': אע"פ שאינו ניכר ר"ל אינו ניכר כשהוא עומד אלא כשהוא מהלך אבל כל זמן שלא יהיה ניכר אפי' בשעת הילוכו אינו מום והלכה כב"ד של אחריהם."5

Translation: "Its foreleg bone was broken and its hind leg bone, even if it is not, etc.: 'Even if it is not noticeable' means it is not noticeable when it is standing, but it is noticeable when it is walking. But as long as it is not noticeable even when walking, it is not a blemish. And the halakha follows the Beit Din shel Achareihem."

Chiddush: The Rambam's chiddush here is to establish a clear, observable threshold for what constitutes a "noticeable" blemish in the context of a broken bone. It's not enough for a bone to be technically broken; it must manifest in a discernible way. A slight limp or an uneven gait visible only when the animal is in motion is sufficient to qualify as a mum. However, if the break is so minor that even a careful observation of its movement reveals no anomaly, it does not constitute a blemish. This reflects a broader principle in halakha that mumin must be mumim niglim (visible blemishes) and not merely mumim nistarim (concealed blemishes), even if physically present. The Rambam further connects this to the psak that follows the later Beit Din, indicating that their rulings on such nuanced observations were accepted as authoritative. This principle, articulated clearly by Rambam, underscores the practical, observable nature of mumin for halakhic purposes, preventing subjective claims of hidden defects from disqualifying kodshim.

2. Tosafot Yom Tov: Authority, Textual Variants, and Anatomical Distinctions

The Tosafot Yom Tov (TYT) offers several insightful comments on this Mishnah, addressing issues of psak, textual fidelity, and the underlying anatomical logic of the Gemara.

a. The Authority of Ila and Beit Din shel Achareihem

The Mishnah states, "מוּמִין אֵלּוּ מָנָה אִילָא בְּיַבְנֶה, וְהוֹדוּ לוֹ חֲכָמִים. וְהוֹסִיף שְׁלֹשָׁה אֲחֵרִים, אָמְרוּ לוֹ: לֹא שָׁמַעְנוּ אֵלּוּ. ... בֵּית דִּין שֶׁל אַחֲרֵיהֶם אָמְרוּ: אֵלּוּ מוּם." (Mishnah Bekhorot 6:8). The TYT elucidates why the halakha follows the later Beit Din:

תוספות יום טוב על משנה בכורות 6:8:2: "אילא . כתב הר"ב שם חכם והוא הנזכר לשבח שהוא מומחה לבכורות במשנה ה' פ"ד. ומש"ה הלכה כב"ד של אחריהם הואיל שהסכימו לדברי זה הבקי. והכ"מ בפ"ז מהל' ביאת מקדש. כתב עוד משום דבתראי נינהו. ועוד דחכמים לא א"ל אלא לא שמענו ואין לא שמענו ראיה. ע"כ. [*ועוד נ"ל מדתנן לקמן במשנה י"א. על אלו מומין כו'. וכללינהו להנך. [ש"מ דהלכה נינהו]:"6

Translation: "Ila: Rabbeinu Ovadiah of Bartenura wrote there (in his commentary to M. Bekhorot 4:5) that he was a Sage, and he is mentioned commendably as an expert in firstborns in Mishnah 4:5. And for this reason, the halakha follows the Beit Din shel Achareihem, since they agreed with the words of this expert. And the Kessef Mishneh in Hilkhot Bi'at Mikdash, Chapter 7, further wrote that it is because they are later authorities (batrai ninhu). And furthermore, the Chachamim only said to him, 'we did not hear,' and 'we did not hear' is not a proof (against it). Up to here. [And it further seems to me that since it is taught later in Mishnah 6:11, 'For these blemishes, etc.,' and it generalizes these, it implies that they are halakha.]"

Chiddush: The TYT, building on the Kessef Mishneh, provides a multi-faceted justification for accepting the rulings of the Beit Din shel Achareihem over the initial reservation of the Chachamim.

  1. Expert Authority: Ila was a recognized mumcheh (expert), and the later Beit Din sided with his expertise, lending weight to his additions.
  2. Chronological Superiority: The principle of "הלכה כבתראי" (the halakha follows later authorities) is invoked. Later batei din often had the benefit of more extensive study or resolved earlier ambiguities.
  3. Nature of Objection: Crucially, the Chachamim's initial response, "לא שמענו אלו" (we did not hear these), is a statement of lack of tradition, not a substantive refutation or disagreement (ein lo shama'anu ra'aya). This distinction is vital in halakhic discourse; absence of evidence is not evidence of absence.
  4. Mishnaic Confirmation: The TYT adds his own chiddush – the subsequent Mishnah (6:11) appears to incorporate these additions into the general category of mumin that permit slaughter, implicitly confirming their halakhic validity.

This analysis by TYT provides a robust framework for understanding how new halakhic insights, especially from experts, gain acceptance and become codified, even when initially met with a lack of prior tradition.

b. Textual Variant: "לא שמענו אלו"

The TYT also highlights a fascinating textual variant related to Ila's additions:

תוספות יום טוב על משנה בכורות 6:8:3: "לא שמענו את אלו . וכן הנוסח בכל הספרים. ורש"י העתיק לא שמענו אלא אלו. וכן מצאתי מוגה במשנה:"7

Translation: "'We did not hear these.' And this is the version in all books. And Rashi copied, 'We did not hear only these,' and so I found it corrected in the Mishnah."

Chiddush: While seemingly minor, the presence or absence of "אלא" (only/except) dramatically shifts the meaning.

  • "לא שמענו אלו" (the standard girsa): "We did not hear these [specific new ones]." This implies a lack of prior tradition, allowing for their potential acceptance once validated.
  • "לא שמענו אלא אלו" (Rashi's girsa): "We heard only these [and no others like them]." This would imply a definitive limitation to the existing list of mumin, directly rejecting Ila's additions as outside the received tradition.

The TYT notes that Rashi's version, if accepted, would make it much harder for Ila's additions to be ratified. The fact that the Beit Din shel Achareihem ultimately accepted them strongly suggests that the girsa without "אלא" is the correct one, or that even if "אלא" was present, it was interpreted in a non-restrictive way. This demonstrates the critical role of girsa (textual variants) in shaping halakhic outcomes and understanding machloket.

c. Anatomical Distinction: "גלגל עינו עגול כשל אדם"

One of Ila's additions, ratified by the later Beit Din, is "את שגלגל עינו עגול כשל אדם" (whose eyeball is round like a person's). The TYT explores the Gemara's discussion (Bekhorot 38b) on this:

תוספות יום טוב על משנה בכורות 6:8:4: "את שגלגל עינו עגול כשל אדם . ואלו הן השלשה שהוסיף את שגלגל עינו כו' רש"י. ובגמ' פרכינן למימרא דלאו היינו אורחיה ורמינהו המפלת מין בהמה כו'. דלר"מ אפי' עינו אחת כשל אדם הוי בהמה. ומשנינן הא באוכמא בשחור של עין שאינו עגול כאדם. הא בצירא [ה"ג רש"י וכך הגירסא בגמ' פ"ג דנדה דף כ"ג] כל בית מושב הלובן והסירא קרוי צירא והוא ודאי עגול כשל אדם ע"כ. ובנדה פ"ג מפרש בהיפך דמקום מושב העין לא הוי עגולי בבהמה כאדם ואי הוי עגול הוי מום. ומיהו כתב הכ"מ בפ"ב מהא"מ דנראה דהרמב"ם לא גרס כל זה ואחריו נמשך הר"ב:"8

Translation: "Whose eyeball is round like a person's: And these are the three that he (Ila) added, 'whose eyeball, etc.' (Rashi). And in the Gemara, we question: 'Is it to say that this is not its usual way? And we raised a contradiction from: "If she miscarried a species of animal, etc." For according to Rabbi Meir, even if it has one eye like a person, it is still an animal.' And we answer: 'This refers to the ochma (the black of the eye) which is not round like a person's (i.e., it is naturally round in an animal). This (the blemish) refers to the tzira (white of the eye). [This is Rashi's version, and this is the girsa in Gemara Niddah 23a, Chapter 3]. The entire area of the white and the iris is called tzira, and that is indeed round like a person's.' Up to here. And in Niddah Chapter 3, it explains the opposite, that the eye socket is not round in an animal as in a person, and if it is round, it is a blemish. However, the Kessef Mishneh wrote in Hilkhot Issurei Bi'ah, Chapter 2, that it appears the Rambam did not have this entire girsa, and Rabbeinu Ovadiah of Bartenura follows him."

Chiddush: This section reveals a deep sugya that relies on precise anatomical distinctions and reconciliation of seemingly contradictory mishnayot.

  • The Contradiction: The Gemara is bothered by the idea that a round eye is a mum. If an animal has a round eye like a human, it's considered a mum for bekhorot. Yet, M. Niddah 3:4 (regarding ha'mafeles, the miscarried fetus) implies that even a creature with a human-like eye is still considered an "animal" if the majority of its features are animal-like. If a human-like eye is a blemish, it implies it's not the normal way of an animal, yet R' Meir still calls it an "animal."
  • The Resolution: The Gemara resolves this by distinguishing between the "ochma" (black pupil/iris) and the "tzira" (white of the eye/sclera). An animal's ochma is naturally round, so a human-like roundness there isn't a mum. However, a human-like roundness in the tzira (the white outer part) is a mum, as an animal's tzira is typically not perfectly round like a human's.
  • Further Nuance & Girsa: The TYT then notes that the Gemara in Niddah 23a seems to reverse this, stating that the eye-socket (makom moshav ha'ayin) in an animal is not round like a human's, and if it is, it's a mum. This highlights the complexity and potential for different interpretations or anatomical understandings across sugyot. The Kessef Mishneh's observation that Rambam (and consequently Rabbeinu Ovadiah) might not have had this detailed Gemara discussion further emphasizes the impact of girsa on psak and the interpretation of mumin.

This detailed analysis by TYT shows how Chazal meticulously define mumin based on what deviates from the derekh (normal way) of a specific animal species, requiring precise anatomical knowledge and careful textual reconciliation.

3. Rashash: The Scope of "מומין אלו מנה אילא"

The Rashash poses a kushya regarding the scope of the phrase "מומין אלו מנה אילא ביבנה" (these blemishes Ila enumerated in Yavne):

רש"ש על משנה בכורות 6:8:1: "במשנה מומין אלו מנה אילא כו'. פירש הרע"ב נשבר עצם ידו כו'. תמוה מדוע לא פירש כפשוטו דקאי אכל הני דחשיב בפרקין עד כאן. וגם לשון מנה אין נופל יפה על שנים לבד. גם לפירושו יהיה התוספות מרובה על העיקר:"9

Translation: "In the Mishnah, 'These blemishes Ila enumerated, etc.' Rabbeinu Ovadiah of Bartenura explained (that 'these' refers to) 'Its foreleg bone was broken, etc.' It is puzzling why he did not explain it according to its simple meaning, that it refers to all these [blemishes] that were listed in the chapter until this point. Also, the term 'enumerated' (manah) does not fit well for only two [blemishes]. Furthermore, according to his explanation, the additions would be more numerous than the main list."

Chiddush: The Rashash challenges the interpretation of Rabbeinu Ovadiah of Bartenura (R'av), who understood "מומין אלו" to refer only to the immediately preceding two examples (broken foreleg/hind leg bones). The Rashash argues for a more expansive reading: "מומין אלו" should refer to all the blemishes listed throughout the entire chapter up to this point. His arguments are:

  1. Simple Meaning: The plain meaning of "these blemishes" is comprehensive, referring to the entire preceding catalog.
  2. Linguistic Fit: The verb "מנה" (enumerated) implies a longer list, not just two items.
  3. Proportionality: If "אלו" refers only to the last two, then Ila's additions (three blemishes) would be disproportionately large compared to the "main" list he's credited with enumerating, which seems unlikely.

The Rashash's kushya highlights the meticulous attention paid to dikduk and the precise scope of Mishnaic phrases. It implicitly questions whether Ila was merely confirming the last few mumin or if he was the primary expert responsible for much of the halakha in this complex chapter. The accepted halakha generally considers all listed mumin as authoritative, irrespective of the precise scope of Ila's initial enumeration, but Rashash's point forces a deeper reflection on the Mishnaic structure.


Friction

One of the most compelling points of friction in this sugya arises from Ila's addition of "את שגלגל עינו עגול כשל אדם" (whose eyeball is round like a person's) as a mum, and the Gemara's subsequent attempt to reconcile this with other halakhot. This tension, elucidated by the Tosafot Yom Tov, reveals the intricate anatomical and halakhic distinctions made by Chazal.

The Strongest Kushya: The "Round Eye" Contradiction

The Mishnah in Bekhorot 6:8, in the context of Ila's additions, states that an animal "whose eyeball is round like a person's" is considered a mum. The implication is that this anatomical feature is not the normal characteristic of an animal, and thus constitutes a defect.

However, the Gemara (Bekhorot 38b) immediately raises a kushya (difficulty) from an earlier sugya in Mishnah Niddah 3:4 (or similar contexts discussing ha'mafeles – miscarried fetuses):

גמרא בכורות לח,ב: "למימרא דלאו היינו אורחיה? ורמינהו: המפלת מין בהמה ועיניה ארוכות כשל אדם, או עינו אחת כשל אדם – הרי זו בהמה." Translation: "Is it to say that this (a round eye) is not its (an animal's) normal way? And let us raise a contradiction: 'If she miscarried an animal species and its eyes were elongated like a person's, or one of its eyes was like a person's – behold, this is an animal.'"

The kushya is as follows: If an animal having an eye "like a person's" (which the Gemara assumes to be round) is a mum because it deviates from the animal's natural form, then why does R' Meir in M. Niddah consider a creature with such an eye to still be an "animal" (and not a human-animal hybrid or a disqualifying anomaly)? The fact that it's still classified as an "animal" implies that a human-like eye, while unusual, isn't so fundamentally aberrant as to change its species-status. If it's an animal, why would a variation within its species (even if human-like) be a mum? The Gemara's initial assumption is that "like a person's" implies a fundamental deviation from animal derech, which should either disqualify it as an animal (in Niddah) or be an obvious mum (in Bekhorot). The contradiction lies in the perceived degree of deviation and its halakhic consequence. If it's derekh an animal enough to remain an animal, why is it a mum? If it's not derekh an animal to be round, why is it still an animal?

The Best Terutz: Anatomical Nuance and Girsa Differences

The Gemara provides a nuanced terutz (resolution) based on precise anatomical distinctions, as highlighted by Tosafot Yom Tov:

תוספות יום טוב על משנה בכורות 6:8:4: "ובגמ' פרכינן למימרא דלאו היינו אורחיה ורמינהו המפלת מין בהמה כו'. דלר"מ אפי' עינו אחת כשל אדם הוי בהמה. ומשנינן הא באוכמא בשחור של עין שאינו עגול כאדם. הא בצירא [ה"ג רש"י וכך הגירסא בגמ' פ"ג דנדה דף כ"ג] כל בית מושב הלובן והסירא קרוי צירא והוא ודאי עגול כשל אדם ע"כ."10 Translation: "And in the Gemara, we question: 'Is it to say that this is not its usual way? And we raised a contradiction from: "If she miscarried a species of animal, etc." For according to Rabbi Meir, even if it has one eye like a person, it is still an animal.' And we answer: 'This refers to the ochma (the black of the eye) which is not round like a person's (i.e., it is naturally round in an animal). This (the blemish) refers to the tzira (white of the eye). [This is Rashi's version, and this is the girsa in Gemara Niddah 23a, Chapter 3]. The entire area of the white and the iris is called tzira, and that is indeed round like a person's.' Up to here."

The Gemara's resolution rests on a distinction between two parts of the eye:

  1. "אוֹכְמָא" (The Black of the Eye): The Gemara states that the "black of the eye" (pupil and iris) in an animal is naturally round. Therefore, if an animal's "ochma" is round like a human's, it is not a blemish, because this is derekh (the way of) the animal. The Gemara's statement "שאינו עגול כאדם" (which is not round like a person) is interpreted as a rhetorical question, implying that the animal's black eye is round. Thus, a round ochma is not a mum.
  2. "צִירָא" (The White of the Eye / Sclera / Iris Area): The Gemara explains that the mum of "round eye like a human" refers specifically to the tzira. The tzira is defined as "כל בית מושב הלובן והסירא" (the entire area of the white and the iris). In animals, this tzira area is typically not perfectly round in the same way a human eye socket or overall eye appearance is. Therefore, if an animal's tzira is perfectly round like a human's, it is a blemish, as it deviates from the animal's natural form.

Reconciling the Sugyot:

  • Mishnah Niddah: When M. Niddah speaks of an animal having an eye "like a person's," it refers to a general resemblance that doesn't fundamentally alter its animal classification. This general resemblance might encompass the naturally round ochma or other features not considered a disabling mum.
  • Mishnah Bekhorot: The mum in Bekhorot is a specific anatomical deviation in the tzira (the overall eye socket/white area) that is considered a significant defect from the perspective of sacrificial purity, even if the creature remains an animal in a broader sense.

Further Complication and Alternative Girsa: The TYT adds a crucial note:

תוספות יום טוב על משנה בכורות 6:8:4: "ובנדה פ"ג מפרש בהיפך דמקום מושב העין לא הוי עגולי בבהמה כאדם ואי הוי עגול הוי מום. ומיהו כתב הכ"מ בפ"ב מהא"מ דנראה דהרמב"ם לא גרס כל זה ואחריו נמשך הר"ב:" Translation: "And in Niddah Chapter 3, it explains the opposite, that the eye socket (makom moshav ha'ayin) is not round in an animal as in a person, and if it is round, it is a blemish. However, the Kessef Mishneh wrote in Hilkhot Issurei Bi'ah, Chapter 2, that it appears the Rambam did not have this entire girsa, and Rabbeinu Ovadiah of Bartenura follows him."

This adds a layer of complexity: The Gemara in Niddah 23a seems to offer a reversed understanding, suggesting that it's the absence of roundness in an animal's makom moshav ha'ayin (eye socket) that is normal, and if it is round, it's a mum. This highlights the dynamic nature of Gemara interpretation and the potential for different schools of thought or girsaot. The Kessef Mishneh's observation that Rambam (and consequently R'av) may not have had this entire sugya with its detailed distinction points to how girsa variations can fundamentally alter the halakhic landscape. If Rambam did not have this Gemara, he would have to interpret "round eye like a person" differently, perhaps based on a simpler understanding of what constitutes an unnatural shape for an animal's eye.

The strength of this terutz (despite the girsa variations) lies in its ability to reconcile two seemingly contradictory mishnayot by introducing a subtle, yet critical, anatomical distinction. It demonstrates Chazal's deep engagement with the physical characteristics of animals and their commitment to deriving consistent halakhic principles, even when facing apparent discord in their sources. The friction here isn't just about a definition of a mum, but about the hermeneutical tools used to build a coherent halakhic system from diverse texts.


Intertext

The meticulous cataloging and definition of mumin in Bekhorot 6:8-9 do not exist in a vacuum. They are deeply rooted in biblical law and find resonance and elaboration in later halakhic literature, particularly concerning the purity of kohanim and sacrificial animals.

1. Tanakh: The Foundational Concept of "Mum"

The concept of "mum" (blemish) as a disqualifying factor for sacred service and offerings is explicitly articulated in Vayikra (Leviticus). The Mishnah in Bekhorot is a direct application and detailed exposition of these foundational principles.

  • Vayikra 21:17-23: This passage deals primarily with the disqualification of kohanim who possess physical blemishes from performing avodah (Temple service).

    "דַּבֵּר אֶל־אַהֲרֹן לֵאמֹר אִישׁ מִזַּרְעֲךָ לְדֹרֹתָם אֲשֶׁר יִהְיֶה בוֹ מוּם לֹא יִקְרַב לְהַקְרִיב לֶחֶם אֱלֹהָיו׃ כִּי כָל־אִישׁ אֲשֶׁר־בּוֹ מוּם לֹא יִקְרָב אִישׁ עִוֵּר אוֹ פִסֵּחַ אוֹ חָרוּם אוֹ שָׂרוּעַ׃ אוֹ אִישׁ אֲשֶׁר יִהְיֶה בוֹ שֶׁבֶר רָגֶל אוֹ שֶׁבֶר יָד׃ אוֹ גִבֵּן אוֹ דַק אוֹ בַּהֶרֶת עֵינוֹ אוֹ גָרָב אוֹ יַלֶּפֶת אוֹ מְרוֹחַ אָשֶׁךְ׃ כָּל־אִישׁ אֲשֶׁר־בּוֹ מּוּם מִזֶּרַע אַהֲרֹן הַכֹּהֵן לֹא יִגַּשׁ לְהַקְרִיב אִשֵּׁי יְהוָה מוּם בּוֹ אֵת לֶחֶם אֱלֹהָיו לֹא יִגָּשׁ לְהַקְרִיב׃ לֶחֶם אֱלֹהָיו מִקָּדְשֵׁי הַקָּדָשִׁים וּמִן־הַקֳּדָשִׁים יֹאכֵל׃ אַךְ אֶל־הַפָּרֹכֶת לֹא יָבֹא וְאֶל־הַמִּזְבֵּחַ לֹא יִגַּשׁ כִּי־מוּם בּוֹ וְלֹא יְחַלֵּל אֶת־מִקְדָּשָׁיו כִּי אֲנִי יְהוָה מְקַדְּשָׁם׃"11 Translation: "Speak to Aaron, saying: No man of your offspring throughout their generations who has a blemish shall draw near to offer the food of his God. For any man who has a blemish shall not draw near: a blind man or a lame man, or one with a mutilated face or a limb too long; or a man who has a broken foot or a broken hand; or a hunchback or a dwarf, or one with a film in his eye, or scabs, or eczema, or crushed testicles. No man among the offspring of Aaron the priest who has a blemish shall approach to present the fire-offerings of the LORD; he has a blemish; he shall not approach to present the food of his God. He may eat the food of his God, from the most holy offerings and from the holy offerings. But he shall not come near the curtain or approach the altar, for he has a blemish, lest he profane My sanctuaries; for I am the LORD who sanctifies them."

  • Vayikra 22:19-25: This passage explicitly prohibits offering blemished animals as korbanot.

    "לִרְצֹנְכֶם תָּמִים זָכָר בַּבָּקָר בַּכְּשָׂבִים וּבָעִזִּים׃ כֹּל אֲשֶׁר־בּוֹ מוּם לֹא תַקְרִיבוּ כִּי לֹא לְרָצוֹן יִהְיֶה לָכֶם׃ וְאִישׁ כִּי־יַקְרִיב זֶבַח שְׁלָמִים לַיהוָה לְפַלֵּא־נֶדֶר אוֹ לִנְדָבָה בַּבָּקָר אוֹ בַצֹּאן תָּמִים יִהְיֶה לְרָצוֹן כָּל־מוּם לֹא יִהְיֶה־בּוֹ׃ עַוֶּרֶת אוֹ שָׁבוּר אוֹ חָרוּץ אוֹ יַבֶּלֶת אוֹ גָרָב אוֹ יַלֶּפֶת לֹא תַקְרִיבוּ אֵלֶּה לַיהוָה וְאִשֶּׁה לֹא־תִתְּנוּ מֵהֶם עַל־הַמִּזְבֵּחַ לַיהוָה׃ וְאֵשֶׁךְ מָעוּךְ וְכָתוּת וְנָתוּק וְכָרוּת לֹא תַקְרִיבוּ לַיהוָה וּבְאַרְצְכֶם לֹא תַעֲשׂוּ׃ וּמִיַּד בֶּן־נֵכָר לֹא תַקְרִיבוּ אֶת־לֶחֶם אֱלֹהֵיכֶם מִכָּל־אֵלֶּה כִּי מָשְׁחָתָם בָּהֶם מוּם בָּם לֹא יֵרָצוּ לָכֶם׃"12 Translation: "For your acceptance, it must be a male without blemish, from the cattle, the sheep, or the goats. Anything in which there is a blemish, you shall not offer, for it will not be acceptable for you. And if a man offers a sacrifice of peace offerings to the LORD to fulfill a vow or as a freewill offering, from the cattle or the flock, it must be without blemish to be accepted; there shall be no blemish in it. Neither blind nor broken nor mutilated nor having a growth nor scabs nor eczema—you shall not offer these to the LORD, nor make an offering by fire of them on the altar to the LORD. And an animal with crushed, mutilated, torn, or cut testicles—you shall not offer these to the LORD, and in your land you shall not do so. Nor from the hand of a foreigner shall you offer the food of your God from any of these, for their mutilation is in them, a blemish is in them; they will not be acceptable for you."

These verses establish the core principle: kodshim must be tamim (whole, unblemished). The Mishnah in Bekhorot then meticulously translates this general biblical mandate into specific, observable criteria for various animal species. The list in Vayikra (blind, lame, broken limb, scabs, etc.) forms the template that Chazal elaborate upon, often defining the precise degree or nature of a defect required to constitute a mum. For example, "שבר רגל או שבר יד" (broken foot or broken hand) in Vayikra 21:19 is echoed in our Mishnah's "נשבר עצם ידו ועצם רגלו," with Chazal adding the crucial nuance of visibility even if only in motion.

2. Shulchan Aruch and Responsa: Codification and Broader Implications

The laws of mumin in bekhorot and other kodshim are codified in the Shulchan Aruch, primarily in Yoreh De'ah Siman 302, which deals with general laws of disqualifying blemishes in animals, including those that render an animal tereifa (non-kosher) or pasul (disqualified for korban).

  • Shulchan Aruch, Yoreh De'ah 302:1: "אין שוחטין את הבכור אלא אם כן נפל בו מום קבוע, אבל מום עובר אין שוחטין עליו."13 Translation: "One may slaughter a firstborn only if a permanent blemish has occurred in it, but one may not slaughter it on account of a temporary blemish." This codifies the Mishnah's distinction between mumin shel keva (constant/permanent) and she'einan shel keva (not constant/temporary), such as the "constant tears" or "pale spots." The Shulchan Aruch then proceeds to list many of the mumin found in our Mishnah, often citing the Rambam and Tur.

  • Tumtum and Androgynus (M. Bekhorot 6:9): The Mishnah concludes with a unique and complex halakha regarding the tumtum (concealed genitals) and androgynus (hermaphrodite), stating that they cannot be slaughtered "neither in the Temple nor in the country." Rabbi Shimon says this is the greatest mum, implying it can be slaughtered. The Chachamim say, "אינו בכור לגזוז ולעבוד" (it is not a firstborn for shearing or labor). This means it is entirely removed from the category of bekhor, essentially treated as hullin from birth.

    This machloket and its psak have profound intertextual connections, particularly in Even Ha'ezer (laws of marriage and divorce) and Choshen Mishpat (laws of inheritance), where the status of a tumtum or androgynus as male, female, or safek (doubtful) is critical.

    • Shulchan Aruch, Even Ha'ezer 44:1: "טוּמְטוּם הֲרֵי הוּא סְפֵק אִישׁ סְפֵק אִשָּׁה, וְאַנְדְּרוֹגִינוֹס הֲרֵי הוּא בְּרִיָּה בִּפְנֵי עַצְמוֹ, יֵשׁ בּוֹ סִימָנֵי אֲנָשִׁים וְסִימָנֵי נָשִׁים. וּמִכָּל מָקוֹם, לְעִנְיַן יוֹרְשׁוֹת וְלַעֲבוֹדָה בַּמִּקְדָּשׁ וְלִבְכוֹרָה וּלְכַמָּה דְּבָרִים דִּינוֹ כְּסָפֵק."14 Translation: "A tumtum is a doubtful male, doubtful female; and an androgynus is a unique creature unto itself, possessing both male and female characteristics. Nevertheless, regarding inheritance, Temple service, firstborn status, and many other matters, its status is like a doubt."

    The Shulchan Aruch here applies the safek (doubt) status to the androgynus for bekhorah as well. The Chachamim's view in our Mishnah, that an androgynus is "not a bechor for shearing or labor," is a decisive ruling that removes it from the kedushat bekhorah entirely, bypassing the safek status for bekhorot. This is because the kedushah of bekhor requires a clear male status. If it's not clearly male, it cannot be a bechor. This demonstrates how the halakhic definition of "male" is critical not only for human gender identity but also for animal sanctity. The Chachamim's psak essentially says that the safek in gender for bekhorot is resolved by disqualification, rather than strict humra (stringency) that would prevent any benefit.

The intertextual connections reveal that the detailed list of mumin in Bekhorot 6:8-9 is not merely an archaic list, but a cornerstone of halakhic jurisprudence concerning sacred objects, drawing directly from biblical mandates and having far-reaching implications across different domains of Jewish law.


Psak/Practice

The detailed enumeration of mumin in Mishnah Bekhorot 6:8-9 forms the bedrock for halakhic practice regarding firstborn animals and the redemption of other kodshim. The psak generally follows the definitive rulings presented in the Mishnah, particularly where a beit din or majority opinion is stated.

1. General Principles of Mum Identification

The core principles derived from this Mishnah and its Gemara are:

  • Mum Kavu'a (Permanent Blemish): Only a permanent blemish allows for the slaughter of a bechor outside the Temple or the redemption of kodshim. Temporary conditions, such as non-constant tears or pale spots ("נימים ודמעות שאינן של קבע"), do not suffice15. This often requires a waiting period or specific tests, as seen with the 80-day rule for constant spots or the fodder test for constant tears.
  • Mum Nigleh (Visible Blemish): The blemish must be externally visible and discernible. Internal or hidden blemishes ("חניכיים הפנימיות שנקמטו ולא נתלשו" – internal gums damaged but not extracted) are generally not considered disqualifying for bekhorot unless they have a visible manifestation16. The Rambam's interpretation of "נשבר עצם ידו ועצם רגלו אע"פ שאינו ניכר" as "not noticeable when standing but noticeable when walking" highlights that even a subtle visible effect is sufficient17. This ensures that the mum is objectively verifiable.
  • Deviation from Derech (Normal Way): A mum is fundamentally a deviation from the natural and healthy form of the animal. This is evident in the specific anatomical details, like an ear lacking cartilage, a pierced eyelid, or a tail that doesn't reach the arkuv. The "round eye like a person" is a prime example of a morphological deviation from the animal norm.

2. Following the Beit Din shel Achareihem

The Mishnah explicitly states regarding Ila's three added mumin ("את שגלגל עינו עגול כשל אדם, ופיו דומה לשל חזיר, ורוב לשונו של דיבור נמרט"), that initially the Chachamim said "לא שמענו אלו" (we did not hear these), but "בית דין של אחריהם אמרו: אלו מום" (the Beit Din that followed them said: these are a blemish)18. The halakha follows this later beit din. As discussed by Tosafot Yom Tov and Kessef Mishneh, this is due to several reasons: they were later authorities (batrai ninhu), they agreed with an expert (baki), and the initial objection was merely a lack of tradition, not a substantive refutation. This principle demonstrates the dynamic evolution and ratification of halakha through successive batei din.

3. The Tumtum and Androgynus

The ruling on the tumtum and androgynus is particularly significant. The Chachamim state, "אינו בכור לגזוז ולעבוד" (it is not a firstborn for shearing or labor), rejecting Rabbi Shimon's view that it is a mum for slaughter. This psak is generally accepted: a tumtum or androgynus is not considered a bechor at all, and thus has no kedushah (sanctity) of a firstborn. It can be shorn and worked like any ordinary animal19. This is a crucial meta-psak heuristic: where there is fundamental doubt about the identity or status required for kedushah (in this case, clear male status to be a "firstborn male"), the default is to assume the absence of kedushah, rather than to treat it with a stringency that would prevent all benefit. It also avoids the safek (doubt) status for bekhorah and resolves it with a definitive status of hullin. This reflects a broader halakhic principle that kedushah often requires certainty and absence of fundamental ambiguity.

4. Meta-Psak Heuristics

This sugya offers several meta-psak heuristics:

  • Expert Authority: The reliance on Ila, a mumcheh le'bekhorot, indicates that specialized knowledge can shape halakha, particularly in technical areas like animal anatomy.
  • "Ein Lo Shama'anu Ra'aya": A lack of tradition is not a valid refutation against a new halakhic insight, allowing for the expansion of halakha through reasoned analysis and expert consensus.
  • Balancing Stringency and Benefit: While kodshim demand purity, Chazal also recognized the need for practical application. Defining clear mumin allows for the release of bekhorot from their intense kedushah when unfit, preventing undue burden on their owners while maintaining the sanctity of the altar.
  • Observable Criteria: The emphasis on visible, permanent, and objectively verifiable mumin ensures that halakhic decisions can be made consistently and without excessive subjective interpretation.

In practice, these detailed laws require expert knowledge, often still necessitating consultation with a mumcheh (or a qualified Rav well-versed in these halakhot) for complex cases of mumin in bekhorot today, especially given the rarity of bekhorot being brought to the Temple.


Takeaway

The Mishnah's meticulous definition of mumin underscores Chazal's rigorous commitment to upholding the sanctity of kodshim through observable, permanent criteria, while simultaneously providing practical mechanisms for handling disqualified animals. It exemplifies how expert tradition, anatomical precision, and dynamic halakhic discourse shape the application of biblical law, even resolving fundamental questions of identity for sacred objects.
