Leviticus 21:21-23

²¹No man of the offspring of Aaron the priest who has a defect shall come near to offer the offerings of the LORD made by fire. Since he has a defect, he shall not come near to offer the bread of his God.

²²He shall eat the bread of his God, both of the most holy, and of the holy.

²³He shall not come near to the veil, nor come near to the altar, because he has a defect; that he may not profane my sanctuaries, for I am the LORD who sanctifies them.’”
