Mishneh Torah, Gifts to the Poor 2-4

Sugya Map

• The Issue: Defining the parameters of Pe'ah (corner of the field) as a mandatory, proactive agricultural divestment.
• Nafka Mina: Does Pe'ah constitute a property transfer in rem (attached to the produce) or in personam (an obligation on the owner)?
• Primary Sources: Leviticus 19:9, Mishneh Torah, Gifts to the Poor 2:1, Pe'ah 2:8.

Text Snapshot

Rambam Gifts to the Poor 2:1 defines the threshold for Pe'ah: "Any food that grows from the earth, is guarded, is harvested at the same time, and is placed in storage is required that pe'ah be separated from it." The nuance here is the definition of a crop. Rambam’s five criteria serve as a litmus test for "harvestable" status.

Readings

• Radbaz (Ad loc): Argues that the owner’s intent to store the produce is the pivot point. If produce is not for storage, it lacks the "harvest" definition of Leviticus 19:9.
• Tzafnat Pa'neach (Rogatchover Gaon): Suggests that the obligation is not merely on the act of harvesting, but on the existence of the crop as a singular, unified economic unit. When the owner harvests "bit by bit" (as in 2:7), he effectively bypasses the legal definition of "harvest," rendering Pe'ah moot.

Friction

Kushya: If the owner is commanded to leave Pe'ah at the end of the field for the poor, why does the Torah not specify a quantity? Terutz: Rambam identifies the mechanism as hefker (renunciation). The owner doesn't "give" a specific percentage; he renders a portion of his standing field ownerless. The "quantity" is defined by the social necessity of the poor to know where to gather, preventing the owner from hiding the Pe'ah in inaccessible locations.

Intertext

The principle that the obligation rests on the standing grain (2:4) mirrors the logic in Chullin 138a, where the Sages prioritize the status of the field at the moment of harvest. This prevents the owner from "pre-empting" the poor by harvesting the corners secretly.

Psak/Practice

Pe'ah is not merely charity; it is a structural limitation on private ownership. In modern agricultural meta-halacha, this implies that any "storage-ready" harvest requires a baseline divestment. Even in the absence of the Temple, the principle of Pe'ah serves as a heuristic for ethical business: one does not fully exploit the "corners" of their profit margin, leaving "gleanings" for those outside the immediate economic loop.

Takeaway

Pe'ah is defined by the nature of the crop (storability) and the method of harvest (totality). If you don't harvest as a unified event, you aren't legally harvesting—and the obligation to the poor remains unfulfilled.
