Peah 5:1-2
Peah 5:1
Let’s say that there’s a pile of produce on top of leket that had not yet been gathered by the needy. Whatever touches the ground belongs to the poor. (This is a penalty imposed on the land owner for covering the leket.) If wind scatters the sheaves, mixing the owner’s produce with the leket, they calculate how much leket there should be and give that to the needy. Rabban Gamliel says they give the needy as much as normally falls.
Peah 5:2
If the top of a stalk reaches the standing grain and that stalk could be reaped with them, it goes to the owner; if not, it goes to the needy. If a leket stalk gets mixed in the pile, the owner takes maaser (tithe) from one stalk and gives that stalk to the needy. Rabbi Eliezer asks how the needy person can trade the leket stalk for this stalk, seeing that the leket stalk has not yet come into his possession. Rather, he says the owner must first transfer the entire pile to the needy person, then take the maaser and give him the stalk. (The difference between the Sages and Rabbi Eliezer hinges on the question of whether the land owner can acquire the leket on behalf of the recipient.)
