Leviticus
Chapters 21:21-24
New International Version Anglicized
21No descendant of Aaron the priest who has any defect is to come near to present the food offerings to the Lord. He has a defect; he must not come near to offer the food of his God.
22He may eat the most holy food of his God, as well as the holy food;
23yet because of his defect, he must not go near the curtain or approach the altar, and so desecrate my sanctuary. I am the Lord, who makes them holy.” ’
24So Moses told this to Aaron and his sons and to all the Israelites.
