Menachot 79

Sugya Map

• Core Issue: Does the disqualification of the Korban Todah (Thanksgiving Offering) retroactively invalidate the sanctification of the accompanying loaves?
• Nafka Mina:
  • Does Kedushat ha-Lechem (the sanctity of the bread) depend on the hechsher (viability) of the animal’s blood, or is it an independent attachment to the act of Shechita?
  • The mechanics of hekesh (analogy): Can we derive disqualifications based on the nature of the pesul (e.g., karet vs. non-karet)?
• Primary Sources:
  • Menachot 79a (Baraita regarding R. Eliezer vs. R. Yehoshua).
  • Leviticus 7:12 (The requirement of loaves for the Todah).
  • Mishnah Menachot 79b (Libations and the requirement of loaves for offspring/substitutes).

Text Snapshot

• "רבי אליעזר אומר: קדשו, ורבי יהושע אומר: לא קדשו" (Menachot 79a): The binary opposition. Note the dikduk in kadshu (active/transitive—the slaughter sanctifies) vs. the passive implication of the pesul.
• "רבי אליעזר אומר: למדנו פסול מחשבה מפסול מחשבה" (Menachot 79a): R. Eliezer’s hermeneutic logic—prioritizing the category of disqualification (intent) over the severity (karet).
• "רבי יהושע אומר: למדנו פסול שאין בו כרת מפסול שאין בו כרת" (Menachot 79a): R. Yehoshua’s pivot—shifting the focus to the legal consequence of the disqualification.

Readings

The Rishonic Perspective: Sanctification as a Function of Intent

The foundational chiddush of the Rishonim, particularly Rashi (ad loc. s.v. למדנו פסול מחשבה), centers on the status of Machshava (intention). R. Eliezer argues that once the Shechita is performed with a defining intent, the lechem is tethered to that act. The chiddush here is that Kedushat ha-Lechem is not merely a byproduct of a "kosher" sacrifice, but an ontological status triggered by the ma’aseh of slaughtering a Todah. For R. Eliezer, the Todah is a vessel for the loaves; if the slaughter occurred, the vessel is consecrated regardless of the subsequent status of the meat.

The Acharonic Synthesis: The "Legal Category" vs. "Intrinsic Sanctity"

In Minchat Chinuch (Mitzvah 140), the discussion expands into whether the loaves possess independent Kedusha. The Acharonim note that if the loaves were dependent on the meat being kasher, they would be nifsal automatically upon the pesul of the meat. However, the fact that R. Eliezer and R. Yehoshua debate the source of the deduction suggests that the lechem occupies a liminal space. If the pesul is chotzot l'zmano (beyond time), the lechem remains sanctified because the act of slaughter was performed within the framework of a Korban. R. Yehoshua’s counter-argument—that we compare to ba'al mum (blemished animals)—posits that the lechem is intrinsically linked to the hechsher of the animal. If the animal is unfit ab initio (or by discovery), the lechem never attains the status of "offering bread."

The Logic of the Silence

R. Eliezer’s eventual silence ("ושתק") is interpreted by the Tosafot as a formal concession of the hermeneutic rule. The chiddush here is that the methodology of derashah determines the outcome of the halacha. By shifting the comparison from Machshava (intent) to Karet (severity), R. Yehoshua proves that the Todah is not a singular entity but part of a system of sacrificial laws where the lechem is subservient to the kashrut of the blood.

Friction

The Strongest Kushya

The primary tension arises from the Gemara’s analysis of the Sin Offering: If a Sin Offering slaughtered chotzot l'zmano does not descend (lo tered), why does the Todah with the same disqualification (according to R. Eliezer) not inevitably sanctify its loaves? The kushya is: Is the lo tered status a result of the Korban having achieved sanctity, or a separate rule that prevents "desecration" of the altar by removing even disqualified items?

The Terutz

The terutz lies in the distinction between kedushat ha-mizbe'ach (the altar's requirement to retain offerings) and kedushat ha-lechem (the specific status of the loaves). The Gemara (Menachot 79a) suggests that the loaves are an adjunct. Rava (retracting to R. Yehoshua’s logic) clarifies that once the hechsher is breached, the lechem loses its "Todah-ness." Therefore, while the Sin Offering might remain on the altar to avoid the appearance of removing holy items, the lechem of the Todah is a specific legal requirement for the eating of the Todah. If the Todah is not fit to be eaten, the lechem cannot be eaten, and thus it cannot be sanctified. The "silence" of R. Eliezer confirms that the lechem is not an independent entity but a satellite of the Korban's viability.

Intertext

Parallel: The Nazirite’s Ram

The Gemara mentions the Nazirite’s Ram (Eilim). In Nazir 45b, the status of the loaves accompanying the Nazirite's ram parallels the Todah. The rule is consistent: if the Shechita is not lishmah, the loaves are not sanctified. This reinforces the meta-halacha that the lechem requires a "perfect" slaughter.

Responsa/SA: Hilchot Korbanot

The Rambam (Hilchot Ma’aseh Ha-Korbanot 15:4) codifies that the loaves are sanctified by the slaughter of the Todah. The Aruch Ha-Shulchan He-Atid (Hilchot Todah) notes that this is the definitive psak: the act of Shechita is the Kinyan (acquisition) of the Kedusha for the loaves, provided the slaughter is not fundamentally flawed by pesul that precedes the act (like a mum).

Psak/Practice

The halacha follows R. Yehoshua: the loaves are only sanctified if the animal is fit for sacrifice. In modern meta-psak, this informs the heuristic of Tzrichut (necessity)—that auxiliary religious requirements (like the loaves) cannot be sanctified if the core commitment (the offering) is invalid. One cannot sanctify the "ornaments" of a service if the "service" itself is fundamentally flawed.

Takeaway

Sanctity is not a blanket that covers a flawed object; it is a legal status predicated on the integrity of the primary act. If the Korban fails, the lechem—no matter how much it was intended for holiness—remains mere dough.
