Chullin 40

Sugya Map

• Issue: The legal effect of a mixed-intent slaughter (shchita) performed by two agents holding a single knife.
• Nafka Mina: Whether "unfit" (pesula) in the Mishnah implies the status of forbidden idol-worship offerings (zivchei metim) or merely invalid meat permitted for benefit.
• Primary Sources: Chullin 40a; Rosh, Chullin 2:13; Rashba, Chullin 40a.

Text Snapshot

• "שנים אוחזין בסכין ושוחטין" (Chullin 40a): Two agents, one intent on a mundane act (davar kasher), the other on an idolatrous/unfit target.
• Leshon nuance: The term pesula is used, yet the Gemara immediately asks if this excludes zivchei metim. The dikduk of the Mishnah’s silence is treated as a substantive legal category.

Readings

• Rosh: Distinguishes between the mountain itself (not idolatry, but forbidden as nichzei—appearing as worship) and the "angel of the mountain" (gada d'har), which constitutes full-fledged avodah zarah.
• Rashba: Offers a meta-halachic insight: The Mishnah's use of pesula is merely a linguistic echo of the previous Tanna’s structure, not a strict exclusionary definition. Intent toward an idol, even if not explicitly defined as such, often defaults to zivchei metim based on context.

Friction

• Kushya: If the slaughter is inherently invalid (pesula) because the act is performed by two, how can we distinguish between "invalid meat" and "forbidden idol offering"?
• Terutz: Abaye’s resolution (Chullin 40a) provides the binary: If the target is a physical, non-divine entity, it is pesula (invalidated by the act of slaughtering to an object that cannot receive status); if the target is a spiritual entity (gada), it is zivchei metim (forbidden benefit).

Intertext

• Avodah Zarah 51b: Parallels the discussion of bitul (nullification) of idolatrous items.
• Shulchan Aruch, Yoreh Deah 146: Codifies these principles; the intent to slaughter to an idol renders the meat neveilah or worse, depending on the status of the "recipient."

Psak/Practice

The heuristic is clear: A person does not render forbidden an item that is not his (Chullin 40a). If the slaughterer has no ownership or authority over the animal, his illicit intent regarding the act of slaughter cannot retroactively contaminate the animal’s status for others.

Takeaway

In shchita, the act is a singular legal unit. If two hands share the knife, the kavanah (intent) of the minority actor can poison the entire process, effectively treating the animal as if it were sacrificed to a false "angel" rather than a mundane "mountain."
