1The LORD said to Moses, "Speak to the priests, the sons of Aaron, and say to them: 'A priest must not make himself ceremonially unclean for any of his people who die,
6They must be holy to their God and must not profane the name of their God. Because they present the food offerings to the LORD, the food of their God, they are to be holy.
10"'The high priest, the one among his brothers who has had the anointing oil poured on his head and who has been ordained to wear the priestly garments, must not let his hair become unkempt or tear his clothes.
21No descendant of Aaron the priest who has any defect is to come near to present the food offerings to the LORD. He has a defect; he must not come near to offer the food of his God.
23yet because of his defect, he must not go near the curtain or approach the altar, and so desecrate my sanctuary. I am the LORD, who makes them holy.'"
