Menachot 23

Sugya Map

• Issue: The parameters of nullification (bittul) in mixtures of min b'mino v'davar acher (same substance with a different substance) and the concept of chiburei oleh (contiguity to items ascending the altar) in determining shiurim.
• Nafka Mina(s):
  1. Validity of a kometz (handful) of a mincha offering when mixed with oil.
  2. Liability for chatzi shiur (less than an olive-bulk) when a bone completes the measure of meat offered b'chutz (outside the Temple courtyard).
• Primary Sources: Menachot 23a; Vayikra 5:11 ("לא יתן עליה שמן ולא יתן עליה לבונה").

Text Snapshot

• Rava's principle on Rabbi Yehuda: "קסבר רבי יהודה: כל שהוא מין במינו ודבר אחר, סלק את מינו כמי שאינו, ודבר אחר רבה עליו ומבטלו." (Menachot 23a)
  • Nuance: Rava posits Rabbi Yehuda's view that in a mixture of "species with its species and something else," one "removes" the same species as if it's not there, and the "something else" (the different species) then nullifies the first. This is a unique bittul mechanism.
• Rava's Dilemma on Chiburei Oleh: "קומץ שמיצה שמנו על גבי עצים מאי? מי אמרינן חבורי עולין כעולין דמו או לא?" (Menachot 23a)
  • Nuance: Rava questions if oil squeezed onto the wood before the kometz is burned is considered part of the kometz due to contiguity to the altar-bound items. This explores how physical connection impacts halachic identity for shiurim.

Readings

• Rashi (Menachot 23a s.v. מין במינו): Clarifies Rava's initial statement: min b'mino refers to oil mixed with oil (from another offering), and davar acher is the solet (flour). This bittul means the solet of the kometz nullifies the other oil, increasing the kometz's oil.
• Tosafot (Menachot 23a s.v. אמר רבא קסבר רבי יהודה כו'): Highlights that this sugya is the ikar (main source) for Rava's statement about Rabbi Yehuda's bittul principle, connecting it to a parallel discussion in Chullin 108a.

Friction

• Kushya: Ravina challenges Rava's chiburei oleh dilemma by equating it to the R' Yochanan/Reish Lakish dispute (Menachot 23a) regarding one who offers a limb of less than a k'zayis of meat, but the bone completes it to a k'zayis.
• Terutz: Rav Ashi distinguishes (Menachot 23a) based on two factors:
  1. Minut: A bone is min basar (same species as meat), whereas oil is not min kometz (same species as the handful of flour). Thus, chibbur might apply differently.
  2. Bar Mefarash: A bone can be separated from the meat ("דבר מפרש הוא") and is not mitzva to return it. Oil, however, is not separable from the kometz ("דלאו בר מפרש הוא") and is integral to its form.

Intertext

The dispute between R' Yochanan and Reish Lakish regarding bone/meat (Menachot 23a) serves as a potent internal intertext. It directly addresses the concept of whether non-consumable parts or adjuncts can complete a shiur, foreshadowing later discussions on shiur k'zayis for various mitzvos and issurim.

Psak/Practice

The sugya underscores the rigorous halachic distinction between a substance's inherent minut (species/type) and its chibbur (connection) to an oleh (altar-bound item). This impacts shiurim for korbanos and potentially for issurei hana'ah (prohibitions of benefit) or shiurei mitzvah (Torah-mandated measures) where tza'ar ba'alei chayim is not a factor. The principle that chibbur might depend on minut or separability is a meta-psak heuristic for defining a shiur.

Takeaway

The Gemara meticulously analyzes the nature of a substance – its type (min) and its physical connection (chibbur) – to determine its halachic identity and contribution to a shiur, particularly in sacred contexts.
