Peah can be given from the beginning of the field or from its middle. R' Shimon says: Provided that he gives at the end [according to] the measure. R' Yehudah says: If he left over a single [un- harvested] stalk, he can attach to it [other produce] as peah; but if not, he can give only as hefker.

One may not [leave] for peah less than [one out of] sixty, even though they said: Peah has no measure. It is all according to the largeness of the field, and according to the abundance of poor people, and according to the abundance of generosity.
