Leviticus 22:5-8 New International Version Anglicized (NIVUK)

5. or if he touches any crawling thing that makes him unclean, or any person who makes him unclean, whatever the uncleanness may be.

6. The one who touches any such thing will be unclean till evening. He must not eat any of the sacred offerings unless he has bathed himself with water.

7. When the sun goes down, he will be clean, and after that he may eat the sacred offerings, for they are his food.

8. He must not eat anything found dead or torn by wild animals, and so become unclean through it. I am the Lord.
