Peah 6:1-2

Peah 6:1

Beis Shammai say that if one declares his property ownerless exclusively for the needy, this is an effective declaration. Beis Hillel say that one cannot declare something selectively ownerless; if he wants to declare it ownerless for the needy, it must also be ownerless for the wealthy, just as we do when it comes to shemittah (when whoever wants produce can come and take it). If all the sheaves in a field are one kav each but there’s one jumbo sheaf that’s four times the size and the jumbo sheaf was left behind, Beis Shammai say it is not shich’cha (because it’s not a sheaf, it’s four sheaves), while Beis Hillel say it is shich’cha (because it’s one sheaf, albeit a very large one).

Peah 6:2

If a sheaf was left next to a stone wall, a pile of sheaves, some work animals or some farm implements, Beis Shammai say that it is not shich’cha (because the owner will invariably remember that it is there), while Beis Hillel say that it is shich’cha (because forgotten is forgotten).
