Leviticus 22:3-7 ▼

3 Say 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.

4 No man of Aaron’s descendants who has a skin disease 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,

5 or whoever touches any swarming creature that makes him unclean or any person who makes him unclean—whatever his uncleanness—

6 the man who touches any of these will remain unclean until evening and is not to eat from the holy offerings unless he has bathed his body with water.

7 When the sun has set, he will become clean, and then he may eat from the holy offerings, for that is his food.
