[If] he found cut [figs] on the road, he may not cut [?] them and walk [and eat] them, because most people are suspected on such matters. [If] he had a stack of onion or dried figs or of carobs on top of his roof, he may sort them and eat, [or] sort them and leave them on the table, [or] sort them and throw them down before his livestock. Rabbi Shimon ben Elazar says, livestock may not eat casually in a courtyard and everyone that brings them from the field into town may not feed them casually, because at the end of it he cannot return the leftover portion (see Maasr. 3:4)
