Leviticus 21:21-23

American Standard Version

²¹ no man of the seed of Aaron the priest, that hath a blemish, shall come nigh to offer the offerings of Jehovah made by fire: he hath a blemish; he shall not come nigh to offer the bread of his God. ²² He shall eat the bread of his God, both of the most holy, and of the holy: ²³ only he shall not go in unto the veil, nor come nigh unto the altar, because he hath a blemish; that he profane not my sanctuaries: for I am Jehovah who sanctifieth them.
