Mishneh Torah, Sabbath 11

Sugya Map

• Issue: The definition of Netilat Neshamah (Taking a Life) on Shabbat.
• Nafka Mina: Whether "slaughter" is a unique category or a subset of a broader prohibition; the status of mekalkel (destructive acts) and melacha she’eina tzricha l’gufa (labor not required for its own sake).
• Primary Sources: Shabbat 74b, 104b, 107a; Mishneh Torah, Hilchot Shabbat 11:1–2.

Text Snapshot

• "השוחט חייב ולא שוחט בלבד אלא כל הנוטל נשמה... בין ששחט בין נחר בין חנק" (11:1).
• Leshon nuance: Rambam groups slaughter, stabbing (nechirah), and strangling under the umbrella of Netilat Neshamah. By emphasizing the result (death) over the method (ritual slaughter), he pivots from the specific act to the essence of the prohibition.

Readings

• Nachal Eitan: Notes the tension between Rav (who posits tzoveia—dyeing the skin with blood—is the core liability) and Shmuel (who argues Netilat Neshamah is the core). Rambam rules like Shmuel, effectively stripping the "ritual" element from the melacha.
• Tzafnat Pa'neach: Explores the intersection of Netilat Neshamah and Mefarek (separating/extracting). He suggests that for Korbanot, multiple liabilities might apply, complicating the leniency of Mitoch (permitting labor for food preparation on Yom Tov).

Friction

• Kushya: If Netilat Neshamah is the core, why is there a separate mention of strangling as a toldah? If death is the goal, the mechanism should be irrelevant.
• Terutz: Strangulation is categorized as a toldah because it lacks the shedding of blood, which is the "standard" or "natural" way life leaves a beast (see 11:1, n. 2). The Av (primary labor) requires the process of bleeding; the Toldah is the result without the conventional process.

Intertext

• SA Orach Chayim 316:9: Echoes Rambam’s ruling on lice; the permission to kill stems from the scientific (or pseudo-scientific) assumption of spontaneous generation from sweat, which exempts them from the "animal" category.

Psak/Practice

• Meta-Psak: The melacha of Netilat Neshamah is strictly prohibited even if the killing is "destructive" (mekalkel). Unlike other melachot where destructive intent exempts the actor, killing is inherently significant because the cessation of life is an absolute change of state.

Takeaway

• Rambam shifts the focus from the act of slaughter to the state of the creature. On Shabbat, "death" is the forbidden result, making the method—whether ritual, clinical, or accidental—secondary to the ontological transformation of a living being into a carcass.
