Leviticus 22:9

5 or whoever touches a crawling creature or a person that makes him unclean, whatever the uncleanness may be—

6 the man who touches any of these will remain unclean until evening. He must not eat from the sacred offerings unless he has bathed himself with water.

7 When the sun has set, he will become clean, and then he may eat from the sacred offerings, for they are his food.

8 He must not eat anything found dead or torn by wild animals, which would make him unclean. I am the LORD.

9 The priests must keep My charge, lest they bear the guilt and die because they profane it. I am the LORD who sanctifies them.

10 No one outside a priest’s family may eat the sacred offering, nor may the guest of a priest or his hired hand eat it.

11 But if a priest buys a slave with his own money, or if a slave is born in his household, that slave may eat his food.

12 If the priest’s daughter is married to a man other than a priest, she is not to eat of the sacred contributions.

13 But if a priest’s daughter with no children becomes widowed or divorced and returns to her father’s house, she may share her father’s food as in her youth. But no outsider may share it.
