Menachot 71

Sugya Map: The Mechanics of Hatarat HaOmer

• Core Issue: When does the Omer permit the new crop (Chadash)? Specifically, what stage of growth (e.g., hashrashah—taking root) is required for the Omer to act as a legal permit?
• Nafka Mina: Can one reap grain for fodder or necessity before the Omer? At what growth threshold does reaping constitute a violation of Katzir?
• Primary Sources: Lev. 2:14 (grain in the ear), Deut. 16:9 (sickle/standing grain), Ex. 23:16 (sowing), Menachot 71a.

Text Snapshot

• Menachot 71a: "מנין לעומר שמתיר בהשרשה?" (From where is it derived that the Omer permits upon taking root?)
• Nuance: The Gemara struggles to ground hashrashah (taking root) in Scripture. Rashi (ad loc. s.v. shematir) explains: "If it took root before the Omer, the Omer permits it, even if it has not grown at all." The logic is an inverse inference: if the Torah specifies "grain in the ear" for the offering, it implies there is a stage before that (rooting) which the Omer nevertheless validates.

Readings

• Rabbeinu Gershom: Highlights that the verse "grain in the ear" (Aviv) is restrictive for the sacrifice, but the permit is broader. He posits that hashrashah is the baseline for legal existence in the field.
• Rava (via Rav Pappa): Challenges the necessity of hashrashah. The debate highlights a tension between formal growth markers and the legal status of the crop as "field-produce."

Friction

• Kushya: If the Omer permits "upon taking root," why does the Mishna later require a complex analysis of "one-third" growth for fodder? If it is already permitted, why does growth matter?
• Terutz: The growth stages determine if the act of reaping itself counts as an agricultural labor. Hashrashah provides the permit (removal of the prohibition of Chadash), but the halakhot of Katzir (reaping) remain governed by whether the grain has reached a maturity threshold.

Intertext

• Pe'ah 2:1: Parallels the dispute on what defines a "field" for Pe'ah. The Gemara (71b) links Katzir prohibitions to Pe'ah definitions, suggesting that "reaping" is a functional legal term rather than a purely botanical one.

Psak/Practice

The halakha generally follows that while Chadash is forbidden until the Omer passes (or the day ends in Chutz La'aretz), specific agricultural actions (like feeding animals) are permissible under limited conditions—provided the crop hasn't reached the maturity that triggers the formal prohibition of Katzir.

Takeaway

The Omer is not merely a ritual sacrifice; it is a legal filter that validates the status of the entire year's crop. Maturity is the biological reality, but hashrashah is the legal threshold for the crop's entry into the Jewish economy.
