Sugya Map
The sugya of Chullin 91a-b stands at the complex intersection of Ma’achalot Asurot (forbidden dietary items) and Kodashim (sacrificial law). The primary engine of the discussion is a structural anomaly regarding the Paschal offering (Korban Pesach): why are the nerves (gidim) and their associated fats (shuman) left over to be burned on the sixteenth of Nisan as notar (sacrificial leftovers)? If these elements are biblically forbidden, they should not possess the status of kodashim fit for consumption, and thus the laws of notar should not apply to them. If they are biblically permitted, they should be eaten to fulfill the positive commandment of eating the Pesach in its entirety.

The Core Halachic Issues
- The Status of Sacrificial Residue (Notar): Does a subjective, non-Torah prohibition (such as a Rabbinic decree or a binding national custom) strip a piece of sacrificial meat of its objective Torah status as "edible" (ra'uy l'achilah), thereby exempting it from the positive commandment of burning leftovers (sereifat notar)?
- The Scope of Gid Hanashe: Does the biblical prohibition of the sciatic nerve apply to both the right and left thighs, and does it encompass the outer nerve (gid hachitzon) and the fat (shumno shel gid), or is it restricted strictly to the inner nerve (gid hapnimi) of the dominant (right) thigh?
- The Mechanics of Forewarning (Hatra'at Safek): Can a person be flogged based on a warning that was uncertain at the time it was delivered? How does Rabbi Yehuda’s position on this systemic criminal law principle reconcile with his specific rulings on the sciatic nerve?
The Nafka Minot (Practical and Conceptual Consequences)
- The Metaphysical vs. Legal Status of Custom (Minhag): If the custom of "Yisrael Kedoshim" (the holiness of Israel to abstain from the fat of the nerve) can generate a status of notar, it implies that custom does not merely bind the person (gavra) but can interact with the objective halachic status of the object (cheftza) under Torah law.
- The Treibering (Nikkur) of Hindquarters: The level of removal required for the outer nerve and the surrounding fat determines whether hindquarter meat can be rendered kosher through standard processing, or if the process is so structurally risky that the entire hindquarter must be sold to gentiles (as is the prevailing Ashkenazic practice).
- The Definition of a Complete Unit (Beryah): If Rabbi Yehuda requires an olive-bulk (kezayit) of the sciatic nerve to incur lashes, he rejects the standard rule that a beryah (a whole organism/unit) is forbidden in any amount. This reshapes the entire conceptual framework of how halachic "units" of food are quantified.

Text Snapshot
The Gemara on Chullin 91a:1 presents two primary resolutions to the problem of why the sinews of the Paschal offering are burned rather than discarded or eaten:
רב אשי אמר: לא נצרכה אלא לשמנו של גיד, דתניא: שמנו של גיד הנשה מותר מן התורה, ואלו ישראל קדושים נהגו בו איסור.
Rav Ashi said: [The Mishnah’s ruling that the sinews must be burned] is necessary only with regard to the fat around the sciatic nerve, as it is taught in a baraita: The fat around the sciatic nerve is permitted by Torah law, but the Jewish people are holy and treated it as forbidden.
רבינא אמר: לא נצרכה אלא לגיד החיצון, וכדרב יהודה אמר שמואל. דאמר רב יהודה אמר שמואל: שני גידים הן, פנימי הסמוך לעצם אסור מן התורה וחייבין עליו, חיצון הסמוך לבשר אסור מדברי סופרים ואין חייבין עליו.
Ravina said: [The Mishnah’s statement] is necessary only with regard to the outer nerve, and it is in accordance with that which Rav Yehuda said that Shmuel said. For Rav Yehuda said that Shmuel said: There are two nerves. The inner nerve that is next to the bone is forbidden by Torah law, and one is liable to be flogged for eating it. The outer nerve that is next to the flesh is forbidden by rabbinic law, and therefore one is not liable to be flogged for eating it.
Textual and Grammatical Nuances
- "ישראל קדושים נהגו בו איסור" (Yisrael Kedoshim nahagu bo issur): The Gemara does not use the standard clinical term for a custom (minhag), but rather frames the practice as an expression of national sanctity (kedushah). The use of the adjective kedoshim (holy) suggests that this is not an arbitrary fence (seyag), but an ontological reality of the Jewish soul that instinctively recoils from this fat. This formulation has deep implications for whether the custom functions as a vow (neder) or as an objective halachic status.
- "הסמוך לעצם" vs. "הסמוך לבשר" (Ha-samuch l'atzem vs. Ha-samuch la-basar): Shmuel’s anatomical division of the sciatic nerve creates a spatial hierarchy of prohibition. The inner nerve, which is physically anchored to the bone, represents the core of the skeletal structure and is forbidden m'de'oraita. The outer nerve, which weaves through the soft tissue, is only forbidden m'divrei soferim (by rabbinic decree). The linguistic choice of samuch (adjacent/clinging) highlights that proximity to the structural core of the animal determines the severity of the biblical prohibition.
Readings
The Rishonim and Acharonim divide sharply over the conceptual mechanisms of Rav Ashi’s and Ravina’s answers, focusing on how a non-biblical prohibition can generate a biblical obligation of notar.
Rashi: The Objective Status of the "Cheftza"
Rashi Chullin 91a:1:2 explains the mechanics of Rav Ashi's statement as follows:
"וישראל קדושים - העושין סייג לתורה נהגו בו איסור והלכך על כרחיך משייר ליה משום מנהגא ושרפה בעי הואיל ומדאורייתא בר אכילה הוא." (And the Jewish people are holy—who make a fence for the Torah, treated it as forbidden. Therefore, of necessity he leaves it over because of the custom, and it requires burning because, on a Torah level, it is fit for eating).
Rashi’s conceptual model is clear: the Torah looks at the objective physical and legal status of the meat. Since the fat is biblically permitted, it is categorized as bar achilah (fit for consumption) under the laws of Kodashim. The fact that the gavra (the individual person) is bound by a custom of holiness not to eat it does not alter the objective status of the meat as sacred, edible food. Because it is objectively edible but subjectively forbidden, it inevitably remains uneaten until morning, triggering the Torah's requirement of notar.

| Meat is Permitted (Bar Achilah) | ===> Objective Status: Holy Food

Tosafot: The Sectarian Nature of Rav Ashi's Resolution
Tosafot Chullin 91a:1:1 raise a powerful structural objection to Rav Ashi’s thesis.
"לא קאי אדרב חסדא דמוקי לה כר' יהודה ולפי מה שאמר לקמן דלר' יהודה שמנו של גיד אפילו מדרבנן שרי לא אתיא אלא כרבי מאיר..." (This does not stand according to Rav Chisda who established our Mishnah in accordance with Rabbi Yehuda. For according to what we say later—that for Rabbi Yehuda, the fat of the nerve is permitted even rabbinically—Rav Ashi's statement can only go according to Rabbi Meir...)
Tosafot point out that on Chullin 92b, the Gemara establishes that Rabbi Yehuda does not recognize any prohibition—even rabbinic or customary—regarding the fat of the sciatic nerve. For Rabbi Yehuda, the fat is completely permitted. Therefore, Rav Ashi’s resolution cannot align with the view that the Mishnah represents Rabbi Yehuda.
Instead, Rav Ashi must hold that the Mishnah follows Rabbi Meir, who holds that the fat is rabbinically forbidden. This means the Gemara’s resolution here is not a universal harmonization but a partisan alignment.
The Rashba: Why Rav Ashi Obscured the Authorship
The Rashba Chullin 91a:1 addresses why Rav Ashi did not simply state that his explanation follows Rabbi Meir:
"והא דלא קאמר הכא לא נצרכה אלא לשמנו של גיד ואליבא דרבי מאיר, משום דההיא ברייתא דישראל קדושים נהגו בו איסור דמייתי לה רבינא לא נזכר בה רבי מאיר." (And that which he did not say here, "It is not necessary except for the fat of the nerve, and according to Rabbi Meir," is because that baraita of "the Jewish people are holy and treated it as forbidden" which Ravina brings does not explicitly mention Rabbi Meir).
The Rashba introduces a methodological principle in talmudic redaction: an Amora will prefer to anchor his explanation in an anonymous, authoritative baraita (Yisrael Kedoshim) rather than explicitly assign it to a disputed Tannaitic name (Rabbi Meir), even if the conceptual mechanics of the baraita ultimately align with that specific Tanna.
The Ritva: The Metaphysical Weight of Custom
The Ritva Chullin 91a:1 takes Rashi’s concept further, exploring the teleological conflict of the Paschal offering:
"פירוש דכיון דאסור מדרבנן לא מצי אכיל ליה וכיון דשרי מדאורייתא באכילה איתא בבל תותירו ולא מצי למשריי'..." (The explanation is that since it is forbidden rabbinically, he cannot eat it; and since it is permitted biblically for eating, it is subject to the prohibition of "do not leave it over," and he cannot simply discard it...)
The Ritva highlights a profound paradox: the Torah commands us to eat the Paschal offering in its entirety and forbids leaving any of it over Exodus 12:10. If a custom or rabbinic decree prevents us from eating a portion of it, are we not actively violating the Torah’s command by allowing it to become notar?
The Ritva answers that the Torah itself respects and integrates the self-imposed boundaries of holiness of the Jewish nation. A custom of abstinence (minhag kedushah) does not constitute a rebellious violation of the positive commandment of achilat Pesach. Rather, the custom creates a state of ones (force majeure) for the gavra, while the cheftza remains holy. Therefore, the meat is left over under the mantle of holiness and must be burned.

[The Ritva's Resolution]
- The custom of "Yisrael Kedoshim" is respected by the Torah.
- It acts as a valid constraint (Ones) on the individual.
- The meat remains holy (Cheftza) but cannot be eaten (Gavra).
- Result: Peaceful co-existence via the mechanism of burning Notar.
Chidushei Rabbeinu Chaim Halevi: The Cheftza/Gavra Split in Notar
To fully appreciate the lomdus of this sugya, we must turn to the conceptual model popularized by the Brisker school (specifically modeled after the analysis of notar in Chidushei Rabbeinu Chaim on the Rambam, Hilchot Ma'achalot Asurot).
Let us analyze the definition of "fit for consumption" (ra'uy l'achilah) in the laws of notar. Is it an objective, physical reality of the meat, or is it a legal-halachic status?
- If it is a legal-halachic status, then any food that is legally forbidden—even by rabbinic decree or custom—should immediately lose its status of ra'uy l'achilah. If it is not ra'uy l'achilah, it cannot become notar, and thus should not require burning.
- If it is a physical reality, then even inherently non-kosher meat (e.g., pig meat) that is physically edible should theoretically be subject to notar if it were somehow offered on the altar. But this is absurd; notar only applies to sanctified, kosher meat.
Rabbeinu Chaim resolves this by splitting the concept of prohibition into two distinct categories:
- Issur בגופו (Inherent Objective Prohibition): A biblical prohibition (such as gid hanashe itself) alters the objective status of the object (cheftza). The Torah declares this item to be "non-food." It is fundamentally lo ra'uy l'achilah. Therefore, it is excluded from the category of notar entirely. It is discarded immediately.
- Issur גברא (Subjective Personal Prohibition): A rabbinic decree (gid hachitzon) or a national custom (shumno shel gid) does not have the power to alter the Torah’s objective definition of the cheftza. Under Torah law, the fat and the outer nerve remain "holy food" (ra'uy l'achilah). The prohibition is merely a personal restriction placed upon the gavra (the person).
Because the cheftza remains objectively permitted and holy on a Torah level, the laws of notar apply to it. Because the gavra cannot eat it due to his subjective restriction, it remains uneaten and must be burned.
Friction
Friction Point 1: The Paradox of Hatra'at Safek (Uncertain Forewarning)
The Gemara on Chullin 91a:2 raises a devastating internal contradiction in Rabbi Yehuda’s jurisprudence.
The Kushya
In the Mishnah on Chullin 96a, Rabbi Yehuda holds that if a person eats the sciatic nerves of both the right and left thighs, he only receives forty lashes (one set), because only one of the thighs is biblically forbidden, but we do not know which one.
The Gemara asks: if Rabbi Yehuda is uncertain which thigh is forbidden, then when the witnesses warned the transgressor before he ate each nerve, their warning was inherently uncertain (hatra'at safek). They could not say with absolute certainty, "You are definitely eating a biblically forbidden nerve," because one of the thighs is permitted!
Yet, Rabbi Yehuda famously rules in the case of the two fathers Chullin 91a:2 that an uncertain forewarning is invalid (hatra'at safek la shemah hatra'ah):
"הכה את זה וחזר והכה את זה... רבי יהודה אומר: באחד פירוש בבת אחת חייב, בזה אחר זה פטור." (If he struck this one and then struck that one... Rabbi Yehuda says: if he struck both simultaneously he is liable, but if he struck them one after the other he is exempt).
In the case of the two fathers, the warning is invalid because at the moment of each strike, the witnesses cannot be certain he is striking his biological father. Why, then, does Rabbi Yehuda penalize the eater of the two sciatic nerves with forty lashes? Since each warning was a hatra'at safek, he should be completely exempt!
[The Hatra'at Safek Contradiction]
Case A: Two Fathers (Chullin 91a:2) Case B: Two Sciatic Nerves (Chullin 96a)
- Strikes one, then strikes other - Eats right nerve, then eats left nerve
- Warning is uncertain each time - Warning is uncertain each time
- R. Yehuda: EXEMPT (No lashes/death) - R. Yehuda: LIABLE (Receives 40 lashes)
==================================================================================
The Core Question: Why does R. Yehuda validate the warning in Case B but not Case A?
The Terutz (The Gemara's Resolution)
The Gemara initially resolves this by stating that the Tanna of the Mishnah on Chullin 96a holds that Rabbi Yehuda does validate hatra'at safek, pointing to the baraita of notar Exodus 12:10. In the case of notar, a person is warned not to leave the meat until morning. This warning is inherently uncertain at the time it is given, because the person still has the physical ability to eat the meat before dawn.
Since Rabbi Yehuda holds that one would be flogged for leaving notar (were it not for the positive commandment to burn it), he must hold that hatra'at safek is a valid warning.
The Deep Lomdish Terutz (Kehillot Yaakov, Siman 32)
The Kehillot Yaakov resolves this friction by distinguishing between two types of "uncertainty" in forewarning:
- Safek במציאות (Uncertainty of Reality/Identity): In the case of the two fathers, the doubt is an objective flaw in the reality of the event. At the moment of the action, the physical identity of the father is a mystery. The warning is fundamentally defective because the transgressor can say, "Perhaps this person is a stranger, and I am committing no crime."
- Safek בתלוי ועומד (Conditional/Future-Dependent Uncertainty): In the case of notar or gid hanashe, the doubt is not a mystery of physical identity, but a future-dependent condition. When the person is warned about notar, the prohibition is clear: "Do not allow this meat to remain until morning." The warning is conditional on his future inaction.
Similarly, regarding gid hanashe, the Torah’s prohibition is clear and absolute: one of these thighs is forbidden. The transgressor knows with absolute certainty that by eating both, he is violating a Torah law.
Therefore, Rabbi Yehuda holds that a conditional or future-dependent warning is valid, whereas a warning plagued by an objective mystery of physical identity (like the two fathers) is invalid.
Friction Point 2: The Beryah Paradox of Rabbi Yehuda
Another major point of friction lies in the quantitative threshold required to incur lashes for the sciatic nerve.
The Kushya
The Gemara on Chullin 91a:3 states:
"אכלו ואין בו כזית - חייב, רבי יהודה אומר: עד שיהיה בו כזית." (If one ate [the sciatic nerve] and its volume is not an olive-bulk, he is nevertheless liable because it is a complete unit (beryah). Rabbi Yehuda says: he is not liable unless it has a volume of at least an olive-bulk).
This is highly problematic. The standard rule in halacha is that a beryah (a whole organism, such as an ant or a complete nerve) is forbidden in any amount (beryah afilu b'chol shehu), and one incurs lashes for eating it even if it is smaller than a kezayit. Why does Rabbi Yehuda reject this universal rule and require a kezayit for the sciatic nerve?
The Terutz (Rishonim and Acharonim)
The Rishonim offer two distinct paths to resolve this friction:
[The Beryah Dispute: R. Yehuda vs. Sages]
|
+---------------------------+---------------------------+
| |
[The Sages' Paradigm] [Rabbi Yehuda's Paradigm]
- Focus: Biological Integrity - Focus: Textual Definition
- The nerve is a "Beryah" (whole unit). - The Torah uses the term "Achilah" (eating).
- Physical wholeness overrides quantitative - Halachic "eating" strictly requires
requirements. a minimum volume of one olive-bulk (Kezayit).
- Result: Liable in any amount. - Result: Exempt if less than a Kezayit.
The Textual Supremacy of "Achilah" (Rashi): Rabbi Yehuda holds that the Torah’s expression of the prohibition of the sciatic nerve is framed under the rubric of "eating" (lo yokhlu - "they shall not eat" Genesis 32:33). In halachic hermeneutics, there is no category of "eating" that is less than the volume of a kezayit.
For Rabbi Yehuda, the ontological status of beryah cannot override the absolute textual requirement of achilah. The Rabbis, however, hold that the unique nature of the sciatic nerve as a complete, independent biological entity (beryah) bypasses the standard quantitative definitions of eating.
The Nerve is Not a Biological "Beryah" (The Ritva): The Ritva Chullin 91a:2 suggests that Rabbi Yehuda holds that a beryah is only recognized if it is a living, independent creature (like an insect) or something that possesses its own life force.
A nerve, while a complete anatomical unit, is ultimately just a part of a larger animal. It does not possess independent biological life. Therefore, Rabbi Yehuda does not classify it as a beryah at all, forcing it to fall back under the standard rules of shiurim (halachic measurements), requiring a kezayit.
Intertext
The discussions on Chullin 91a-b do not exist in a vacuum; they resonate across the biblical narrative, the codes of the Shulchan Aruch, and the literature of the Rishonim on the mechanics of notar.
1. The Interplay with Shulchan Aruch, Yoreh Deah 65
The practical translation of Shmuel’s anatomical division of the inner and outer nerves, as well as Rav Ashi’s discussion of the fat, is codified in Shulchan Aruch, Yoreh Deah 65:1:
"גיד הנשה נוהג בבהמה וחיה הטהורים... ושני גידים הם: הפנימי הסמוך לעצם, והחיצון הסמוך לבשר. הפנימי אסור מן התורה וחייבים על אכילתו כזית מלקות; והחיצון אינו אסור אלא מדברי סופרים." (The sciatic nerve is practiced in pure domestic and wild animals... and there are two nerves: the inner one next to the bone, and the outer one next to the flesh. The inner is forbidden by Torah law, and one is liable to lashes for eating an olive-bulk of it; and the outer is only forbidden by rabbinic law).
The Shulchan Aruch directly adopts the position of Shmuel as explained by Ravina on Chullin 91a:1. Furthermore, in Shulchan Aruch, Yoreh Deah 65:10, the Rama addresses the fat of the nerve:
"שמנו של גיד מותר מן התורה, וישראל קדושים נהגו בו איסור... ועכשיו נהגו לאסור כל השומן שעל הגיד." (The fat of the nerve is permitted by Torah law, but the Jewish people are holy and treated it as forbidden... and now the custom is to forbid all the fat that is upon the nerve).
The Rama’s gloss demonstrates the immense power of the talmudic concept of Yisrael Kedoshim. What began as a voluntary custom of self-restraint in the Tannaitic era has, through centuries of communal practice, crystallized into an absolute, non-negotiable halachic prohibition. The Rama treats the fat with the same practical severity as a Torah-level ban, illustrating how minhag can transform the landscape of kosher food processing.

2. The Parallel in Pesachim 83a-b
The Gemara in Mishnah Pesachim 7:10 and its subsequent analysis in Pesachim 83a-b serves as the sister sugya to our text. The Mishnah there states:
"העצמות והגידין והנותר ישרפו בששה עשר." (The bones, the sinews, and the leftovers shall be burned on the sixteenth).
The Gemara in Pesachim challenges this ruling using the exact same dialectic found in Chullin: why are the sinews (gidim) burned? If they are forbidden, they are not sanctified meat; if they are permitted, they should be eaten!
The Gemara in Pesachim 83a-b goes through the same resolutions: Rav Ashi offers shumno shel gid and Ravina offers gid hachitzon.
This cross-talmudic duplication highlights a fundamental redactional reality: the redactors of the Talmud (the Stammaim) viewed the laws of the Paschal offering and the laws of dietary prohibitions as a unified halachic ecosystem. The conceptual definitions of "food" and "sanctified meat" must remain perfectly consistent across both tractates.
Psak/Practice
How does the intricate lomdus of Chullin 91a manifest in contemporary halacha and modern kosher meat production?
1. The Death of Hindquarter Kosher in Ashkenazic Communities
The practical consequence of the severe prohibitions surrounding the inner nerve, the outer nerve, and the surrounding fats (shumno shel gid) is the complete avoidance of hindquarter meat in most Ashkenazic communities.
[The Hindquarter Halachic Dilemma]
|
+--------------------------+--------------------------+
| |
[The Sephardic Practice] [The Ashkenazic Practice]
- Rely on skilled "Menakkrim" (veiners). - The process of "Nikkur" is highly complex.
- Physically extract the inner/outer nerves - High labor costs + severe risk of error.
and all associated fats. - Meta-Halachic Decision: Avoid hindquarters.
- Hindquarter meat remains kosher and available. - Sell entire hindquarter to non-kosher markets.
To render the hindquarter of an animal kosher, one must perform nikkur (treibering/veining). This involves physically tracing and extracting:
- The biblically forbidden inner nerve (gid hapnimi).
- The rabbinically forbidden outer nerve (gid hachitzon).
- The customary forbidden fats (shumno shel gid).
Because these nerves and fats are woven deeply into the premium cuts of the hindquarter (such as the filet mignon, sirloin, and flank steaks), the process of nikkur is incredibly labor-intensive, delicate, and highly prone to human error.
In Ashkenazic lands, where skilled menakkrim (veiners) were scarce and the risk of violating a Torah-level prohibition was deemed too high, the community adopted a meta-halachic heuristic: it is better to forfeit the premium hindquarter cuts entirely and sell them to the non-kosher market than to risk a failure in the complex process of nikkur.
Consequently, in North America and Europe, Ashkenazic kosher meat is sourced exclusively from the forequarters (up to the twelfth rib). In Israel and some Sephardic communities, skilled nikkur is still practiced, allowing them to consume hindquarter meat.
2. The Halachic Power of "Yisrael Kedoshim"
The concept of Yisrael Kedoshim nahagu bo issur serves as a primary source for the binding authority of communal customs (minhagim). It establishes that when the Jewish nation collectively adopts a stringency to safeguard the Torah, that stringency ceases to be a mere voluntary act of piety (chassidut). It is elevated to a binding legal reality that:
- Restricts the gavra from consuming the item.
- Is recognized by the Torah as a valid reason for meat to remain uneaten, thereby triggering the laws of notar.
- Cannot be dissolved without formal annulment of vows (hatarat nedarim), and in many cases, becomes a permanent generational obligation.
Takeaway
The custom of Yisrael Kedoshim transforms the subjective pursuit of holiness into an objective halachic reality, proving that when the Jewish people choose to restrict themselves for the sake of heaven, the Torah itself rewrites its laws of sacrifice to accommodate their devotion.
