Chullin 66

Sugya Map

• Issue: The classification of locusts (ḥagavim) and the hermeneutic expansion of kosher species.
• Primary Sources: Leviticus 11:21, Chullin 66a.
• Nafka Mina: Whether a "long-headed" grasshopper is permitted.
• Hermeneutic Conflict:
  • Tanna D’Bei Rav: Applies Kelal u’Perat (Generalization and Detail), restricting the category to species strictly resembling the named ones.
  • Tanna D’Bei Rabbi Yishmael: Applies Kelal, Perat, u’Kelal (Gen-Det-Gen), which functions as an amplification (ribbui) allowing for species with even one shared sign.

Text Snapshot

The Gemara pivots on the interpretation of Leviticus 11:21. The text reads: "Yet these may you eat of all winged swarming things that go upon all fours, which have jointed legs above their feet, wherewith to leap upon the earth."

• Rashi 66a s.v. "Tanna D'Bei Rav": Identifies this as the Sifra (Torah Kohanim), the standard curriculum of the Beit Midrash.
• Rashi 66a s.v. "B'Mai Kamiflugi": Clarifies that the debate hinges on the Solam. For Rav, it is a specific inclusion; for the school of R' Yishmael, it serves as a pivot for the Kelal-Perat-Kelal structure, expanding the definition of "kosher" to include the long-headed variety.
• Dikduk Nuance: The repetition of "after its kinds" (l'minehu) is the fulcrum. For Rav, it acts as a limiter; for R' Yishmael, it acts as a bridge between generalizations.

Readings

1. Tosafot (66a s.v. B’mai Kamiflugi)

Tosafot grapples with the scope of the disagreement. If the Tanna D'Bei Rav holds that we only include what is explicitly in the detail, why don't we see a nafka mina regarding grasshoppers that possess all four signs of the Mishna but are not named in the Torah? Tosafot suggests a clever chiddush: perhaps no such creature exists—any insect meeting the four signs is ipso facto of the species listed. Alternatively, Tosafot adopts the rubuta (the "greater case") approach: the debate is framed around the "long-headed" variety precisely because it is the most excluded case. If it is permitted by R' Yishmael, the principle of expansion is established.

2. The Rashash (66a s.v. T’D B’mai)

The Rashash provides a corrective to Rashi’s framing of the locusts' status. He emphasizes that locusts do not require shechita because the Torah categorizes them as distinct from both cattle (behema) and birds (of), drawing from the Halakhot Gedolot. The Rashash is meticulous: he notes that the Gemara’s inclusion of "those coming from the selula" must be reconciled with the Mishna’s prohibition of those found in the hands of a merchant, indicating that the status of the creature is not just a matter of species, but of hecher (recognizability).

Friction

The Kushya

The most potent tension lies in the Gemara’s meta-hermeneutic: "The first generalization is not similar to the latter generalization" (66a). If the first kelal ("jointed legs") and the second kelal ("after its kinds") define "kosher" differently (one based on legs, one based on all four signs), how can they function as a unified Kelal-Perat-Kelal structure? The structure requires logical consistency between the generalizations.

The Terutz

The Gemara invokes the "Western" (Eretz Yisrael) school of interpretation: when two generalizations are juxtaposed, we treat them as a single, amplified category regardless of their internal definition variance. This is a radical move—it suggests that for the school of R' Yishmael, the syntax of the Torah overrides the semantic difference between the two generalizations. The "generosity" of the Torah, as Rabbi Abbahu notes, is precisely this: the Holy One expanded the definitions to ensure that the category of "permitted" is as wide as the text can possibly accommodate.

Intertext

• I Samuel 17:5: The Gemara uses the reference to Goliath's "scale armor" (kaskasim) to define kaskeset. This serves as a vital intertextual anchor: the word for fish-scales is the same as the word for protective military gear. This informs the Halacha—a scale must be "removable" and "protective" in a manner analogous to physical armor, not merely a skin pigmentation.
• Niddah 51b: The cross-reference here is essential for the psak of fish. The rule "Any fish with scales has fins" is a taxonomic absolute. The Gemara uses this to prove that if the Torah mandates both, it is to emphasize the severity of the prohibition (a double-transgression of positive and negative commandments).

Psak/Practice

In practical Halacha, the status of the ḥagav is largely dormant due to the loss of masorah (tradition) regarding the specific species. However, the heuristic remains live: when dealing with kelalim and peratim, the "school of R' Yishmael" approach—which favors an expansive, inclusive reading of Torah categories—is a fundamental pillar of darshanut.

Furthermore, the fish psak is absolute: if a fish has scales, it is kosher. The "fins" requirement is technically redundant in practice, but legally essential as a "guardrail" (gader) to prevent the ingestion of non-kosher species that might appear to have scales.

Takeaway

The debate on the long-headed locust is a masterclass in hermeneutics: Rav restricts via the Detail, while R' Yishmael expands via the Structure. We learn that the Torah's definitions are not merely biological, but syntactic, and that the "greatness" of the Torah lies in its deliberate, expansive ambiguity.
