Chullin 21

Sugya Map: The Mechanics of Melikah (Pinching)

• Core Issue: Does the halakhic definition of "death" (in the context of tum'ah and korbanot) require the actual severance of the head, or merely the destruction of the vital life-force (simanim)?
• Nafka Mina: Whether a bird remains tahor (pure) if the neck is broken but the head is still attached, and whether melikah performed on a bird that is already halakhically dead (due to trauma) is valid.
• Primary Sources: Chullin 21a; Oholot 1:6; Leviticus 1:15; 5:10.

Text Snapshot

• "וכי מתה עומד ומולק" (Chullin 21a) – Rashi (s.v. מ"מ קשיא): "Does one stand and pinch a dead [bird]?"
• "בלא רוב בשר" (Chullin 21a) – Rashi (s.v. בלא רוב): "Without the majority of the width of the flesh of the spine, for it is not yet dead, as Ze'eiri speaks of [severing] the spine and the majority of the flesh."
• Nuance: The Gemara struggles to define the threshold of mitah (death). If the neck is broken with the majority of the flesh, it is a corpse. If without, it is "living" enough to be validly pinched.

Readings

• Rabbeinu Gershom: Highlights that the act of gistera (splitting widthwise) renders the animal a nevelah (carcass) because the physical trauma is irreparable. He emphasizes the metzias (reality) of the organism's viability.
• Rashash: Focuses on the textual precision of the beraita, noting that the definition of "two" simanim vs. "majority of two" is a structural machloket regarding the definition of korban vs. tum'ah standards.

Friction

• Kushya: If the simanim (windpipe/gullet) are the source of life, why does the extent of the severed flesh (rov basar) dictate tum'ah?
• Terutz: The Gemara distinguishes between the korban requirement (where melikah must be an active, ritualized death) and the tum'ah requirement (where the body's integrity is compromised). The "death" is a threshold of physical discontinuity, not merely the cessation of breath.

Intertext

• I Samuel 4:18: The death of Eli. The Gemara uses this as an ex-post-facto proof that trauma to the neck bone, when combined with age/weight, creates a "dead" status, distinguishing between accidental trauma and ritual precision.

Psak/Practice

• Meta-Psak: In hilkhot shechitah, the standard for "life" is the simanim. However, Chullin 21a teaches that there is a secondary threshold of "irreversibility." Even if the animal isn't strictly dead by simanim standards, if it is "collapsed and visibly lacking" (Chullin 21a), it may be trefah or nevelah.

Takeaway

Halakhic "death" is not a singular point of expiration but a spectrum of physical integrity. The melikah of a korban requires a specific, controlled transition—if you kill the bird before the ritual, you have a carcass, not a sacrifice.
