Chullin 137

Sugya Map

• Issue: The hermeneutical preference (Heikish/Gezera Shava) for defining Reishit HaGez (first shearing).
• Nafka Mina: Whether the obligation extends to oxen, goats, or depends on the volume of wool.
• Primary Sources: Deuteronomy 18:4, Job 31:20, Chullin 137a.

Text Snapshot

The Gemara notes: "And these halakhot common to the first sheared wool and the firstborn are more numerous (ve-ha-nach nafishi) than those shared by the first sheared wool and animal tithe" Chullin 137a. The dikduk here is vital; the Gemara weighs the "density" of shared legal traits against the "thematic alignment" (applying to ordinary animals) preferred by Rabbi Shimon.

Readings

• Rashi: Argues that while Reishit HaGez and the Firstborn share "saleability," the Tithe is restricted by the phrase "it shall not be sold" Leviticus 27:28. Rashi (s.v. u-mekhira) notes the tension regarding whether these gifts constitute mamon ha-ba'alim (owner's property) valid for kiddushin.
• Rashash: Critiques Rashi’s internal logic, noting that while Rashi attempts to justify using Tithe for kiddushin, the Mishnah in Ma'aser Sheni 4:1 explicitly forbids it, creating a sharp conflict between the status of the item and its utility in acquisition.

Friction

Kushya: If the Firstborn and Reishit HaGez are structurally more similar (both are exempt from formal hekdesh), why does Rabbi Shimon prioritize the Tithe? Terutz: Rabbi Shimon prioritizes functional scope. Because both Reishit HaGez and Tithe apply to "ordinary" animals—rather than being restricted by the "womb" status of the Firstborn—the shared category of "commonality" outweighs the numerical count of shared administrative halakhot.

Intertext

• Job 31:20: Used as the linguistic bridge for "shearing," but also as a physical qualifier: wool that does not provide warmth (tzomran kasheh) is excluded.
• Tzom Gedaliah Connection: Just as the Rabbis debate the "measure" (1/60th) of Pe'ah and Terumah in the face of scarcity, Tzom Gedaliah reminds us that even when our resources are diminished, the halakhic obligation to provide for the needy remains legally defined and non-negotiable.

Psak/Practice

The principle that halakha prefers broad thematic resonance over superficial administrative parallels is a core interpretive heuristic. In practice, this determines the "threshold" of obligation—not just the quantity of wool, but the type of animal and the manner of harvest.

Takeaway

Legal taxonomy is not a numbers game of overlapping rules; it is a search for the underlying essence. Rabbi Shimon teaches us that defining a mitzvah requires identifying its "population"—whether it touches the extraordinary (Firstborn) or the ordinary (Tithe)—more than counting the technical similarities between them.
