Chullin 65
Sugya Map
The sugya of Chullin 65a serves as a locus classicus for the intersection of biblical orthography, taxonomic classification, and the structural limits of midrashic hermeneutics. The Gemara transitions from an orthographic inquiry regarding compound words to the anatomical and behavioral criteria of kosher birds, culminating in an intricate analysis of the hermeneutical derivations governing kosher grasshoppers (chagavim).
The Core Issues:
- Orthographic Status of Compound Names: Whether compound biblical terms, specifically bat ya’ana (the ostrich) and Chedorlaomer, are legally classified as single or dual entities, and how this scribal division impacts halachic derivation (e.g., the status of its egg).
- Avian Kashrut Taxonomy: The interplay between anatomical signs—an extra digit (etzba yeteirah), a crop (zefek), a peelable gizzard (kurkevan nitlaf)—and behavioral/ecological indicators, such as predatory clawing (dores), snatching food in mid-air (choteph ve'ochel), and social association (the zarzir and the crow).
- Orthopteran Kashrut and Hermeneutic Mechanics: How the four biblically permitted grasshoppers (arbeh, solam, hargol, chagav) and their respective "kinds" (le-minehu) are expanded via Klal u'Prat u'Klal (Generalization-Particularization-Generalization) and Binyan Av (Inductive Paradigm) to include or exclude atypical variants, such as long-headed grasshoppers (rosho aroch) and the tzartzur (cricket).
Halachic Nafka Minas (Practical Ramifications):
- Scribal Integrity (Tikkun Sofrim): Whether a scribe who splits bat ya’ana across two lines invalidates a Sefer Torah, and conversely, whether splitting Chedorlaomer across two lines is similarly disruptive.
- Avian Kashrut Assessment in the Absence of Masoret: Whether a bird exhibiting certain physical signs, or satisfying the behavioral test of not snatching food in mid-air, can be deemed kosher without an unbroken chain of oral tradition (masoret).
- Grasshopper Permissibility: The precise physical parameters (length versus circumference coverage of the wings) required to permit a locust, and the contemporary reliance on masoret for consuming chagavim.
Primary Source Trajectory:
- Biblical Text: Leviticus 11:13-19 (prohibited birds), Leviticus 11:21-22 (permitted swarming winged insects).
- Mishnaic Foundation: Mishnah Chullin 3:6 (the baseline signs of birds and grasshoppers).
- Talmudic Discussion: Chullin 65a (the syntactic and hermeneutical breakdown).
- Halachic Codification: Rambam, Hilchot Ma'achalot Asurot 1:15-20; Shulchan Aruch, Yoreh Deah 82 (birds) and Yoreh Deah 85 (grasshoppers).

בתרתי תיבות שמע מינה תרי שמות נינהו. אלא מעתה כדורלעמר דכותב סופר בתרתי תיבות הכי נמי דתרי שמות נינהו? אמרי: התם כותב סופר בתרתי תיבות, אבל בתרתי שיטין לא; הכא אפילו בתרתי שיטין נמי כותב.
Translation & Linguistic Analysis
"Into two words, conclude from it that they are two names [prohibiting the egg as well]. If that is so, what about the name 'Chedorlaomer' Genesis 14:4 which the scribe splits in two—is it also true there that they are two names? They say: There, with regard to Chedorlaomer, the scribe splits the name into two words, but he may not split it into two lines. But here [with bat ya'ana], he may split the name even into two lines." [^1]
Philological and Orthographic Nuances
- בתרתי תיבות (In two words): The Gemara interrogates the orthographic presentation of bat ya'ana (בת יענה). If written as two distinct lexical items, it implies a dual semantic nature: bat (daughter) and ya'ana. This split has immediate halachic relevance regarding the status of its egg: is the egg prohibited because it is part of the mother, or does the name itself denote a compound structure that includes the egg?
- בתרתי שיטין (In two lines): The ultimate test of lexical unity in scribal halacha (halachah le-Moshe mi-Sinai) is the line-break constraint. A truly unified compound name, such as Chedorlaomer (כדורלעמר), may be written as two words on a single line to aid legibility or spacing, but it cannot be cleaved across a line-break (the end of one line and the beginning of the next). To do so would suggest to the reader that two distinct historical figures or concepts are being discussed.
- Bat ya'ana, however, is so fundamentally distinct in its compound parts that a scribe may split it across two lines. This orthographic independence confirms that the Torah views the bat and the ya’ana as structurally separate, which the Gemara leverages to prohibit the egg of an unclean bird.
Readings
The structural density of Chullin 65a has generated rich interpretive systems among the Rishonim and Acharonim. Below, we analyze three primary areas of commentary: the orthography of compound names, the taxonomy of avian kashrut, and the hermeneutics of Rabbi Yishmael’s school.
1. Rashi: Scribal Orthography and Textual Redundancy
Rashi, navigating the transition from orthography to hermeneutics, provides the foundational definitions for the scribal mechanics and the school of Rabbi Yishmael.
On the scribal splitting of bat ya'ana:
בתרתי - בשתי תיבות:
Rashi notes that writing a name in two words is a localized scribal phenomenon, but it is the line-break (shitin) that possesses legal weight.[^2] If a scribe splits Chedorlaomer across two lines, the scroll is invalid (pasul), as it destroys the integrity of the single historical monarch. Bat ya’ana, conversely, remains kosher even when split across lines because the "daughter of the ya'ana" is a composite biological description rather than a singular proper noun.
On the hermeneutics of the school of Rabbi Yishmael:
דבי ר' ישמעאל תנא - הנך למינהו לאו פרטי נינהו כדאמרת דלא מרבי אלא מינא דכל חד אלא כללי נינהו ויש כאן כללי כללות ופרטי פרטות...
Rashi explains that the repeated phrase "after its kinds" (le-minehu) is not a restrictive clause limiting each permitted grasshopper to its immediate biological family.[^3] Rather, the school of Rabbi Yishmael treats these repetitions as "generalizations of generalizations" (klalei klalot) and "particularizations of particularizations" (pratei pratot).
This structural reading transforms the biblical text from a static list of four permitted insects into a dynamic matrix of physical features. The repeated "after its kinds" operates as a redundant generalizer, designed to drag otherwise excluded species into the sphere of permissibility based on overlapping morphological profiles.
2. Tosafot: The Structural Mechanics of Klal u'Prat and the "Shushifa" Controversy
Tosafot embark on a highly complex analysis of the hermeneutical transition from Klal u'Prat (General-Particular) to Binyan Av (Inductive Paradigm), while also resolving a major cross-talmudic contradiction regarding the long-headed grasshopper (shushifa). [^4]
The Structure of Rabbi Yishmael's Derivation
Tosafot address why the Gemara requires a Binyan Av (common denominator) derived from three species (arbeh, hargol, solam) if the text has already employed a series of Klal u'Prat u'Klal formulas.
According to the Ri (Rabbeinu Yitzchak), each of the three species represents a distinct anatomical archetype:
- Arbeh (the migratory locust) has a rough forehead and no tail.
- Solam (the bald locust) has a smooth forehead and no tail.
- Hargol (the long-horned grasshopper) has a tail.
If the Torah had only written Klal u'Prat u'Klal on arbeh, we would only permit grasshoppers that mimic the arbeh (rough forehead, no tail). By writing le-minehu after each distinct archetype, the Torah establishes three independent Klal u'Prat frameworks.
However, to permit a species that possesses a long head (rosho aroch)—a feature not present in any of the explicit biblical paradigms—we cannot rely on Klal u'Prat alone, as a long head represents a significant morphological departure. We must therefore construct a Binyan Av from all three to isolate the true halachic indicators of kashrut (four legs, four wings, jumping legs, and wings covering the majority of the body), proving that head shape is halachically irrelevant.
The "Shushifa" Contradiction
Tosafot confront a severe contradiction between our sugya and Shabbat 90b. In Shabbat, the Gemara relates that Rav Kahana passed a shushifa over his mouth, and Rav told him to remove it so people would not think he was eating a non-kosher insect. This implies that a shushifa—which the Gemara in Avodah Zarah 37a defines as a long-headed grasshopper (rosho aroch)—is actually forbidden, or at least highly suspect.
How can our sugya permit a long-headed grasshopper via the redundancy of solam, while the sugya in Shabbat treats the shushifa as forbidden?
ונראה לר"ת דגרס התם דכולי עלמא לא פליגי דשרי וכן מצא בספר ישן:
To resolve this, Rabbeinu Tam (R"T) proposes a radical textual emendation (garsa) for the sugya in Avodah Zarah: everyone actually agrees that the shushifa is permitted. The dispute in Avodah Zarah between Yossi ben Yoezer and the Rabbis was not about whether a long-headed grasshopper is permitted, but rather about the status of a different species (ayil kamsa) or whether its liquid secretions are pure.
Alternatively, the Ri suggests that there are two distinct types of long-headed grasshoppers: one that possesses all four basic kosher signs (which is permitted by our sugya), and one that lacks these signs (which is the forbidden shushifa discussed in Shabbat).
3. Rabbeinu Gershom: Categorical Clarification
Rabbeinu Gershom, the "Light of the Exile," provides a highly systematic taxonomy of the various "kinds" included by the school of Rabbi Yishmael.[^5] He maps the obscure Aramaic and Hebrew terms of the baraita to distinct ecological niches:
- ציפורת כרמים (Vineyard bird): A small, grasshopper-like insect found on grapevines, included via the arbeh generalization because of its rough, unpolished forehead.
- אושכף (Ushkaf): A bald, smooth-headed variant, included via the solam generalization.
- כרספת ושיחלנית (Karsefet and Shahlanit): Tail-bearing variants, included via the hargol generalization.
By categorization, Rabbeinu Gershom demonstrates that the four biblical terms are not merely four species, but are rather four genera, under which dozens of sub-species are subsumed through the hermeneutical force of le-minehu.
4. The Rashash: Textual Precision on Tosafot
The Rashash (Rabbi Shmuel Strashun) focuses on the micro-mechanics of Tosafot’s reading of the baraita.[^6] He notes that the text of Tosafot must be carefully emended to reflect that the final generalization of chagav ("after its kinds") is specifically designed to enforce the requirement that the insect must be popularly called a chagav while still possessing all four anatomical signs:
תד"ה אלו. ולמינהו דחגב להצריך כל הד' סימנים. כצ"ל:
The Rashash points out that without this precise reading, we would fall into a logical loop: if the name chagav is sufficient, why do we need the signs? If the signs are sufficient, why do we need the name? The le-minehu of chagav acts as a binding agent, dictating that nomenclature and anatomy must align.
Friction
The intellectual engine of our sugya is the dialectical sparring between the anonymous voice of the Gemara (Stamma d'Gemara) and Rav Ahai, who seeks to dismantle the school of Rabbi Yishmael’s reliance on a three-part Binyan Av. Unpacking this friction reveals a fundamental debate about the logical limits of induction.
The Kushya: The Structural Vulnerability of Binyan Av
The school of Rabbi Yishmael attempts to permit a long-headed grasshopper (rosho aroch) by constructing a Binyan Av from three biblical paradigms: arbeh, hargol, and solam. The logic of a Binyan Av relies on isolating a common denominator (hatzad hashaveh):
- Arbeh has signs A, B, C, D (four legs, four wings, jumping legs, covering wings) but has a rough forehead and no tail.
- Hargol has signs A, B, C, D but has a tail.
- Solam has signs A, B, C, D but has a smooth forehead.
The common denominator is that they all possess signs A, B, C, D, and they are all kosher. Therefore, any insect with signs A, B, C, D should be kosher, even if it has a long head.
Rav Ahai presents a devastating pircha (refutation):
מה לכולהו שכן אין ראשן ארוך!
"What is unique about all of these? That their heads are not long!" [^7]
In classical talmudic logic, a pircha on a Binyan Av is fatal. If the target case (the long-headed grasshopper) lacks a physical characteristic shared by all the paradigms from which the rule is derived (i.e., a short head), the induction collapses. You cannot prove that a long head is halachically irrelevant when every single permitted case in the source database features a short head.
The Terutz: The Mechanics of Redundancy (Mufne)
To rescue the kashrut of the long-headed grasshopper, the Gemara must abandon the standard, non-redundant Binyan Av and pivot to the concept of textual redundancy (mufne). Rav Ahai himself provides the solution:
אלא אמר רב אחאי: סלעם יתירא הוא. לכתוב רחמנא ארבה וחרגול, וליתו סלעם מינייהו...
"Rather, Rav Ahai said: Solam is redundant. Let the Merciful One not write solam, and let it be derived by inference from the common denominators of arbeh and hargol..." [^8]
The Logical Redundancy of Solam
If we only had arbeh (rough forehead, no tail) and hargol (smooth forehead, has a tail), could we derive solam (smooth forehead, no tail)?
- If you try to exclude solam because it has a smooth forehead, we can point to hargol, which has a smooth forehead and is kosher.
- If you try to exclude solam because it has no tail, we can point to arbeh, which has no tail and is kosher.
Thus, the common denominator of arbeh and hargol perfectly covers the morphological profile of solam. Why, then, did the Torah write solam?
The Principle of Im Eino Inyan
Because solam is logically entirely redundant, its presence in the biblical text is freed (mufne) to be applied elsewhere via the hermeneutical rule of Im eino inyan le-gupho, tnahu inyan le-davar acher (If it is not needed for its own subject, apply it to another subject).
We therefore apply the redundant word solam to permit the long-headed grasshopper. Because this derivation relies on a direct textual decree (gzeirat ha-katuv) via redundancy rather than pure logical induction, it is entirely immune to the pircha of "their heads are not long."

Analytical Lomdus: Morphological Variation vs. Appendages
A deeper conceptual question arises: why did the Gemara initially think a long head required a special derivation, whereas other variations did not?
In the conceptual world of lomdus, we must distinguish between a shinnuy tzurah (a modification of an existing organ, such as a head being long instead of short) and a tosefet evar (an entirely new anatomical appendage, such as a tail).
One might have argued that a tail (hargol) is a major structural addition, requiring a specific biblical verse to permit it. A long head, however, is merely a proportional variation of a standard organ. Why couldn't a simple Binyan Av absorb a long head without requiring the redundancy of solam?
The answer lies in the ancient taxonomic perception of the head. In ancient biology, the head (rosh) is the locus of identity. A radical alteration in head structure (making it long, like a horse or a dog—hence some locusts being called locusta equina) is not a mere proportional variation; it is a fundamental shift in the animal's "face" (partzuf).
Because a long head threatens to classify the insect under a different category of "creeping thing" (sheretz), the Binyan Av of short-headed insects cannot naturally include it. Only the absolute, sovereign power of a redundant biblical word (solam) can bridge this taxonomic chasm.
Intertext
To fully grasp the halachic and conceptual weight of Chullin 65a, we must examine its parallels in scribal law and its sociological application in the broader Talmudic corpus.
1. The Orthographic Parallel: Chedorlaomer and Potiphar
The Gemara’s discussion of compound words split across lines (shitin) directly impacts the laws of writing Sifrei Torah. The primary parallel is found in Masechet Sofrim 5:10, which lists names that are written as two words but treated as one entity.
The Rambam codifies this in Hilchot Sefer Torah:
שמות שכותבין אותן בשתי תיבות... כגון כדורלעמר, בית אל, בית און... ואם כתבן בתיבה אחת או שכתב שם משאר השמות בשתי תיבות - לא יסתר, ויש מי שאומר שבית אל ובית און וכדורלעמר שכתבן בשתי תיבות וחילק אחת מהן בסוף השיטה וחציה בראש השיטה - שהוא פסול.
"Names that are written in two words... such as Chedorlaomer, Beit-El, Beit-On... if a scribe wrote them as one word, or wrote other names as two, the scroll is not invalid. However, there are those who say that if one wrote Beit-El, Beit-On, or Chedorlaomer as two words and split one of them at the end of a line... the scroll is invalid." [^9]
This directly codifies our Gemara's distinction. While ordinary compound phrases like bat ya'ana can be split across lines because they represent a generic description (the "daughter of the ostrich"), proper nouns like Chedorlaomer—despite their compound linguistic origins (likely Chaldæan: Kudur-Lagamar, "Servant of Lagamar")—possess a unified historical identity. Splitting them across lines violates the semantic integrity of the text, rendering the Sefer Torah invalid according to the strict view.
2. The Ecological/Behavioral Parallel: "Birds of a Feather"
The Gemara in Chullin uses a famous ecological observation to establish a legal presumption:
לא לחינם הלך זרזיר אצל עורב אלא מפני שהוא מינו.
"It was not for naught that the starling went to dwell with the crow, but because it is of its kind." [^10]
In our sugya, the "Others" (Acherim) use this principle to establish a behavioral test for kashrut: if an unknown bird associates with non-kosher birds, it is presumed non-kosher.
This behavioral heuristic is imported into the world of social psychology and tort law in Bava Kamma 92b:
מנין שאין הרשע שותף לצדיק? שנאמר: לא לחינם הלך זרזיר אצל עורב אלא מפני שהוא מינו.
"How do we know that a wicked person should not partner with a righteous person? As it is said: 'It was not for naught that the starling went to dwell with the crow...'" [^11]
In the context of kashrut, this raises a profound conceptual question: is social association an independent cause of impurity, or is it merely an indicator of preexisting anatomical impurity?
If it is an independent cause, then a starling is rendered non-kosher because it behaves like a crow. If it is merely an indicator, the starling’s association with the crow simply reveals its inner biological reality.
The Gemara’s resolution—that the starling is actually kosher because it does not resemble the crow morphologically—proves that anatomical reality always overrides behavioral association. Association creates a chazakah (presumption), but physical evidence (simanim) dissolves it.
Psak/Practice
How does the intricate taxonomic and hermeneutical analysis of Chullin 65a manifest in practical, contemporary halacha?
1. Avian Kashrut: The Loss of Simanim
While the Torah and the Gemara outline clear physical signs (simanim) to identify kosher birds (extra digit, crop, peelable gizzard, and not being a predator), contemporary halacha has fundamentally shifted away from empirical observation to historical tradition (masoret).
The Shulchan Aruch codifies this transition:
אין לאכול שום עוף אלא במסורת שקבלו בו שהוא טהור.
"One may not eat any bird unless there is an established tradition (masoret) that it is kosher." [^12]
The Shach (Siftei Kohen) explains that we are no longer expert in the precise definition of dores (predatory clawing). Because a bird might appear to possess the three kosher physical signs but actually be a predator in private, we cannot rely on our own empirical observations. The theoretical taxonomy of Chullin 65a remains highly active in study, but practical kashrut relies exclusively on a living chain of transmission.
2. Grasshopper Kashrut: The Yemenite Exception
The Mishna and Gemara outline the four physical signs of a kosher grasshopper: four legs, four wings, jumping legs (karayim), and wings covering most of the body.
The Shulchan Aruch rules:
חגבים הטהורים, יש בהם ארבעה סימנים... ובכולן צריך שיהיה שמו חגב.
"Kosher grasshoppers possess four signs... and in all of them, the insect must be known by the name chagav." [^13]
The Rama (Rabbi Moses Isserles) adds a critical limiting clause:
ואנו אין אנו בקיאים בהם, ואין לאכלם אלא במסורת.
"And we are not experts in them; therefore, one should not eat them unless there is an established tradition." [^14]
Because Ashkenazic and most Sephardic communities lost the linguistic and biological tradition identifying which specific species are called chagav, they banned the consumption of all locusts and grasshoppers.
However, the Jews of Yemen maintained an unbroken, highly precise oral tradition (masoret) identifying the desert locust (Schistocerca gregaria) as the biblical arbeh (known in Arabic as al-jarad).
When Yemenite Jews immigrated to Israel, halachic authorities (such as Rabbi Yosef Qafih and Rabbi Ovadia Yosef) debated whether their localized masoret could obligate or permit consumption for non-Yemenite Jews.
The consensus of contemporary posekim is that while Ashkenazim should continue to abstain due to their own lack of tradition, the Yemenite masoret is historically and biologically authentic, satisfying all the rigorous hermeneutical criteria established by the school of Rabbi Yishmael on Chullin 65a.

Halachic taxonomy is never merely empirical; it is a linguistic matrix where physical reality is validated only when it is bound to a biblical name and mapped through the rigorous pathways of midrashic hermeneutics.
