Leviticus 21:21-23

Living Bible

²¹ although he is a descendant of Aaron—he is not permitted to offer the fire sacrifices to the Lord because of his physical defect. ²² However, he shall be fed with the food of the priests from the offerings sacrificed to God, both from the holy and most holy offerings. ²³ But he shall not go in behind the veil, nor come near the altar, because of the physical defect; this would defile my sanctuary, for it is Jehovah who sanctifies it.”
