Leviticus 22:4-6

New Revised Standard Version Catholic Edition

⁴ No one of Aaron’s offspring who has a leprous^[a] 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, ⁵ and whoever touches any swarming thing by which he may be made unclean or any human being by whom he may be made unclean—whatever his uncleanness may be— ⁶ the person who touches any such shall be unclean until evening and shall not eat of the sacred donations unless he has washed his body in water.
