No one of Aaron's offspring who has a leprous disease or suffers a discharge may eat of the sacred donations until he is clean. Whoever touches anything made unclean by a corpse or a man who has had an emission of semen,
everything that can withstand fire, shall be passed through fire, and it shall be clean. Nevertheless it shall also be purified with the water for purification; and whatever cannot withstand fire, shall be passed through the water.
