Leviticus 22:2–7

²“Direct Aaron and his sons to deal carefully with the sacred donations of the Israelites, which they dedicate to me, so that they may not profane my holy name: I am the Lord.^{* 3}Say to them, ‘If anyone among all your offspring throughout your generations comes near the sacred donations, which the Israelites dedicate to the Lord, while he is in a state of uncleanness, that person shall be cut off from my presence: I am the Lord.’^{* 4}No one of Aaron’s offspring who has a defiling skin disease or suffers a discharge may eat of the sacred donations until he is clean. Whoever touches anything made unclean by a corpse or a man who has had an emission of semen,^{* 5}and whoever touches any swarming thing by which he may be made unclean or any human being by whom he may be made unclean—whatever his uncleanness may be^*—⁶the person who touches any such shall be unclean until evening and shall not eat of the sacred donations unless he has washed his body in water. ⁷When the sun sets he shall be clean, and afterward he may eat of the sacred donations, for they are his food.
