Leviticus 21
21 Ref no man of the seed of Aaron the priest, who has a blemish, shall come near to offer the offerings of Yahweh made by fire. Since has a blemish, he shall not come near to offer the bread of his God.
22 Ref He shall eat the bread of his God, both of the most holy, and of the holy.
23 Ref He shall not come near to the veil, nor come near to the altar, because he has a blemish; that he may not profane my sanctuaries, for I am Yahweh who sanctifies them.'"
