Chullin 83

Sugya Map

• Issue: The intersection of Lavin (prohibitions) and Aseh (positive commands), the mechanics of kinyan (acquisition) on festivals, and the gezeira of shema yisaref (fear of accidental loss).
• Nafka Mina: Liability for malkot (lashes) when a prohibition is coupled with a mitzvah to rectify it; the validity of oral/financial kinyan vs. meshikha (pulling).
• Primary Sources: Leviticus 22:28, Chullin 83a, Mishnah Chullin 5:6.

Text Snapshot

Chullin 83a: "בא הכתוב ליתן עשה... לומר שאין לוקין עליו." (The verse comes to provide a positive mitzvah to burn the leftovers... to say one is not flogged for it.) The dikduk here is precise: the mitzvah of bi'ur (burning) renders the lav (prohibition) into a lav ha-nitak le-aseh.

Readings

• Rashi (83a s.v. Ba Ha-Katuv): Highlights the hiddush that even an hatra'at safek (uncertain warning) might have resulted in lashes if not for the aseh. The mitzvah functions as a structural barrier to punishment.
• Rabbeinu Gershom (83a s.v. Miltah Agav Orchei): Observes the meta-halachic social insight: the groom’s household exerts more effort than the bride’s. He interprets the mishnah’s detail as a lesson in derech eretz regarding the hierarchy of wedding preparations.

Friction

Kushya: If meshikha is required by chachamim to prevent the seller from being careless (the shema yisaref concern), why does the mishnah allow financial kinyan on the four festival days? Terutz: As Rabbi Yochanan explains, the Sages suspended their protective decree on these days to facilitate simchat yom tov. The need for meat for the festival outweighs the risk of the seller's negligence.

Intertext & Psak

• Cross-Ref: This reflects the broader Talmudic principle that kinyan by kesef (money) is d'oraita, while meshikha is d'rabbanan Bava Metzia 47b.
• Psak: Halacha follows the mishnah regarding the four days; we create a specialized legal environment when public necessity (simchah) demands the mitigation of standard commercial stringencies.

Takeaway

The mitzvah of burning leftovers transforms a prohibited act into a managed process, mirroring how the Sages recalibrated property law to prioritize communal joy over individual risk. On this Erev Tish'a B'Av, we reflect on the inverse: when simchah is curtailed, the law shifts to emphasize memory and the weight of what is "left over" from our past.
