Leviticus 21:21-24

²¹No man of the seed of Aaron the priest that hath defect shall come near to present Jehovah's offerings by fire: he hath a defect; he shall not come near to present the bread of his God.

²²The bread of his God, of the most holy and of the holy, shall he eat;

²³only he shall not come in unto the veil, nor shall he draw near unto the altar; for he hath a defect: that he profane not my sanctuaries; for I am Jehovah who do hallow them.

²⁴And Moses told it to Aaron, and to his sons, and to all the children of Israel.
