[If] brothers divided [an inherited field], they give two peahs. [If] they resumed their partnership, they give one peah. [If] two [people] bought a tree, they give one peah. [If] this one bought its northern side and this one [bought] its southern side —- this one gives peah for himself and this one gives peah for himself.  [If] one sells tree sprouts within his field, he gives peah from each one. Said R' Yehudah: When [is this]? When the owner of the field did not leave over; but if the owner of the field left over, he gives peah for all.
