Chullin 87

Sugya Map

• Issue: Does the act of covering blood (kisui ha-dam) constitute an hesek ha-da'at (interruption of intent) between successive acts of shechita?
• Nafka Mina: Whether one must recite a new blessing for a second bird after covering the blood of the first, or if the initial birkat ha-mitzvah extends to both.
• Primary Sources: Chullin 87a, Leviticus 17:13, Pesachim 102a.

Text Snapshot

The Gemara contrasts the student’s request for a cup of Grace after Meals (Birkat HaMazon) with the slaughterer’s task: "There, it is impossible to drink and recite a blessing simultaneously... Here, it is possible to slaughter... and cover... with the other hand" (Chullin 87a). The dikduk here emphasizes efshar (possibility) as the litmus test for hesek.

Readings

• Rashi (Chullin 87a s.v. mishta): Argues the students’ request for a cup signaled a definitive cessation of drinking, thus the blessing breaks the continuity. Conversely, one who covers blood remains mentally anchored in the slaughter process; the physical act of covering does not mandate a psychological reset.
• Tosafot (Chullin 87a s.v. mishta): Disputes the R"i who suggests that interrupting a meal to pray requires a new Mezonot or Birkat HaMazon. Tosafot argues that while Birkat HaMazon is a gmar ma'aseh (conclusion of the meal), prayer is not, and thus does not necessarily invalidate the continuity of the meal.

Friction

• Kushya: If efshar (possibility) defines the lack of interruption, why is the act of covering blood not considered an interruption simply because it is a distinct mitzvah (as some suggest)?
• Terutz: The Gemara posits that since one could perform them simultaneously (one hand for each), the covering is legally subsumed under the umbrella of the slaughterer's ongoing work. It is not an interruption because it is not a cessation of intent.

Intertext

• Pesachim 102a: Discusses the "interruption" of leaving a study hall to attend synagogue. The precedent established there—that shared intent keeps the status quo—mirrors the logic applied here to the slaughterer.

Psak/Practice

The poskim (e.g., Shulchan Aruch, Yoreh De'ah 28) lean toward the view that while one may cover between slaughters, it is prudent to avoid unnecessary chatter. The meta-heuristic is clear: hesek is defined by the loss of the "slaughtering mindset." If the act (covering) serves the slaughter, it is part of the flow; if it is extraneous, it breaks the chain.

Takeaway

The halachic definition of an "interruption" is not merely the passage of time or the performance of a second act, but the abandonment of the initial kavanah. If you can physically maintain the task while performing the sub-act, the mitzvah remains a singular, unbroken continuum.
