• Primary Sources: Leviticus 11:21, Chullin 66a, Sifra Shemini.

Text Snapshot

The Gemara asks regarding the disagreement between the Tanna d’Bei Rav and the Tanna d’Bei Rabbi Yishmael: “במאי קא מיפלגי... בחגב שראשו ארוך” (In what do they disagree? Regarding a grasshopper whose head is long). The Tanna d’Bei Rav restricts the category to the species explicitly listed (or those identical in form), while the School of Rabbi Yishmael employs Klal-Prat-u-Klal logic to broaden the inclusion criteria, asserting the Torah’s intent is to maximize permissible species Isaiah 42:21.

Readings

• Rashi (66a s.v. Tanna d’Bei Rav): Notes that the Tanna d’Bei Rav rejects the Klal-Prat-u-Klal derivation because the two generalizations are not structurally identical. The first ("jointed legs") is a functional requirement, while the second ("after its kinds") is taxonomic. Without structural parity, he reverts to the stricter Klal u-Prat.
• Tosafot (66a s.v. B’Mai): Identifies a critical halachic byproduct: Chagavim do not require shechita. By placing them in the verse alongside fish rather than land animals, the Torah implies they are "ready" for consumption without the ritual slaughter required for Behema or Of.

Friction

Kushya: If the Torah provides specific criteria (four signs) for Chagavim, why does it need to add Solam and Hargol? Terutz: The School of Rabbi Yishmael argues that if only the four signs were listed, we might exclude anything not matching the "norm." The inclusion of Solam—which carries a long head—forces an expansion of the category, proving the signs are not a restrictive "closed set" but a baseline for eligibility.

Intertext

• Shabbat 90b: Supports the Tosafot position that Chagavim are distinct from land-based sheratzim regarding ever min ha-chai, as they are not subject to the laws of shechita required for "meat."
• Shulchan Aruch, Yoreh De'ah 85:1: Codifies the signs for Chagavim, reflecting the broad permissive stance of the Tanna d’Bei Rabbi Yishmael.

Psak/Practice

The halacha follows the School of Rabbi Yishmael’s expansive approach: provided the four signs (legs, wings, jumping ability, and proper classification) are present, the grasshopper is permitted. Meta-halachically, this reflects the principle that where the Torah provides signs, it intends to define a broad, accessible category rather than a restricted, elusive one.

Takeaway

The Torah’s inclusion of specific species like Solam functions as a hermeneutical "buffer," ensuring that taxonomic variation does not collapse the category of the permitted.
