Leviticus 22:4-6

New Catholic Bible

⁴ “Any descendant who is a leper or who has a discharge shall not eat of the holy things until he is clean. Whoever touches anything made unclean by contact with a dead person or who has had an emission of semen ⁵ or whoever touches any creeping thing that can make him unclean, or touches a man whose uncleanness he acquires, whatever the source of uncleanness, ⁶ if someone touches one such a person, then he shall be unclean until the evening, and he shall not eat of the holy things unless he bathes himself with water.
