Leviticus 21:21-23

New Revised Standard Version, Anglicised

²¹ No descendant of Aaron the priest who has a blemish shall come near to offer the Lord’s offerings by fire; since he has a blemish, he shall not come near to offer the food of his God. ²² He may eat the food of his God, of the most holy as well as of the holy. ²³ But he shall not come near the curtain or approach the altar, because he has a blemish, that he may not profane my sanctuaries; for I am the Lord; I sanctify them.
