Chullin 30

Sugya Map

• Issue: The mechanical definition of sheḥita (slaughter): Is it a process (teḥila v’ad sof) or a point-in-time culmination?
• Nafka Mina:
  1. The status of a Paschal offering slaughtered with chametz (leaven).
  2. The validity of discontinuous cuts (sheḥita b’shtayim o’ b’shalosha mekomot).
• Primary Sources: Chullin 30a-b; Pesachim 63a; Jeremiah 9:7 (the shaḥut metaphor).

Text Snapshot

• 30a: "Shmuel said: It is derived from a verse, as the verse states: 'Their tongue is a sharpened (shaḥut) arrow' (Jeremiah 9:7). Just as an arrow is propelled by drawing... so too, sheḥita must be performed by drawing the knife."
• Nuance: The Gemara pivots from halachic abstraction to the physical ma’aseh (act), using the arrow as a paradigm of directional force versus impact.

Readings

• Rashi (30a s.v. Sutimta'ah): Explains that the tanna remains anonymous (stam) when citing R. Elazar b. R. Shimon. He highlights that R. Elazar’s view—that slaughter is a single moment—creates a kushya regarding the Red Heifer: why doesn't the tanna distinguish between the first and second cloth?
• Rosh (2:4:2): Defends the validity of cutting in multiple places. He rejects Rashi’s "sequential" interpretation (which implies sheḥita mefure'et—a prohibited, interrupted slaughter) in favor of the She'iltot model: the cuts occur on the same circumference of the simanim.

Friction

• Kushya: If sheḥita requires a "clear and obvious" motion (sheḥita mefure'et is invalid), how can we permit two people or two knives?
• Terutz: R. Yirmeya (30a) resolves this by proposing a single, unified diagonal stroke ("like a reed"). The ma'aseh remains a single, continuous vector, even if the physical contact points appear fragmented.

Intertext

• SA (Yoreh De'ah 21:1): Codifies that sheḥita must be a "drawing" motion (hachlakah). The Shulchan Aruch mirrors the Gemara’s concern: if the knife is concealed (chalada), the slaughter is invalidated because it lacks the "clarity" required by the shaḥut derivation.

Psak/Practice

The psak follows the Rosh and Rashba: while cutting in multiple places is technically permissible if the total cut reaches the rov (majority) of the simanim, it is a bedi'avad (post-facto) leniency. The l’chatchila (ideal) remains a singular, unobstructed draw. Practically, this informs the strict prohibition against de'chika (pressing) versus hachlaka (sliding)—the latter creates the legal status of sheḥita.

Takeaway

Sheḥita is not merely the severance of tissue, but a directional act of "drawing." If the motion is broken or concealed, the act loses its legal character as a korban or mita (permitted meat), regardless of whether the simanim were eventually severed.
