Leviticus 22:4-5

New International Version

⁴ “‘If a descendant of Aaron has a defiling skin disease^[a] or a bodily discharge,^(A) he may not eat the sacred offerings until he is cleansed. He will also be unclean if he touches something defiled by a corpse^(B) or by anyone who has an emission of semen, ⁵ or if he touches any crawling thing^(C) that makes him unclean, or any person^(D) who makes him unclean, whatever the uncleanness may be.
