Leviticus 22:2–7

²“Tell Aaron and his sons to deal respectfully with the holy offerings of the Israelites that they have consecrated to me, so they do not profane my holy name;^a I am the Lord. ³Say to them: If any man from any of your descendants throughout your generations is in a state of uncleanness yet approaches the holy offerings that the Israelites consecrate to the Lord, that person will be cut off from my presence; I am the Lord. ⁴No man of Aaron’s descendants who has a skin disease^F or a discharge is to eat from the holy offerings until he is clean. Whoever touches anything made unclean by a dead person or by a man who has an emission of semen, ⁵or whoever touches any swarming creature that makes him unclean or any person who makes him unclean—whatever his uncleanness—⁶the man who touches any of these will remain unclean until evening^b and is not to eat from the holy offerings unless he has bathed his body with water. ⁷When the sun has set, he will become clean, and then he may eat from the holy offerings, for that is his food.^c
