Beis Shammai say: We may pick up bones and husks from the table. But Beis Hillel say: One must pick up the entire table board and shake it. We may remove from the table [even] crumbs less than the size of an olive, as well as the pods of chickpeas and the pods of lentils, because they are animal fodder. A sponge, if it has a leather handle, we may wipe with it; if not, we may not wipe with it. The Sages, however, say: In either case, it may be moved about on the Sabbath, and it is not susceptible to tumah-contamination.
