Leviticus 22:4-7

⁴None of the descendants of Aaron who has an infectious skin disease, or an infection flowing from his body, may eat any of the sacrifices made to Yahweh until he is clean. Whoever touches anything unclean through contact with the dead, or by contact with a man who has a flow of semen,

⁵or whoever touches any creeping animal that makes him unclean, or any person who makes him unclean, whatever kind of uncleanness it may be—

⁶then the priest who touches anything unclean will be unclean until evening. He must not eat any of the holy things, unless he has bathed his body in water.

⁷When the sun has set, he will then be clean. After sunset he may eat from the holy things, because they are his food.
