One who pronounces a vow [prohibiting] his wife to have marital relations, Beis Shammai say: Two weeks, but Beis Hillel say: One week. [If] she miscarries during the night beginning the eighty-first [day], Beis Shammai exempt [her] from [additional] offer-ings, but Beis Hillel obligate [her to bring additional offerings]. [Regarding] tzitzis in a linen night-cloak, Beis Shammai exempt it, but Beis Hillel obligate [it]. A basket of fruit for the Sabbath, Beis Shammai exempt it, but Beis Hillel rule [that it becomes] subject [to the tithing ob-ligation].
