Leviticus 22:3-5

New Catholic Bible

³ “Say to them: Any of your descendants who approaches these holy things that the children of Israel have consecrated to the Lord while he is unclean, that person will be cut off from my presence. I am the Lord.

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,
