[If] a chaver and an am haaretz inherited their father, an am haaretz, [the chaver] may say to [the am haaretz]: ‘‘You take the wheat that is in such-and-such place, and I the wheat that is in such-and-such place; you the wine that is in such-and-such place, and I the wine that is in such-and-such place.’’ But he may not say to him: ‘‘You take the wheat and I the barley; you take the wet and I will take the dry.’’
