1The LORD said to Moses: "Speak to Aaron's sons, the priests, and tell them: A priest is not to make himself ceremonially unclean for a dead person among his relatives,
6They are to be holy to their God and not profane the name of their God. For they present the fire offerings to the LORD, the food of their God, and they must be holy.
10"The priest who is highest among his brothers, who has had the anointing oil poured on his head and has been ordained to wear the clothes, must not dishevel his hair or tear his clothes.
12He must not leave the sanctuary or he will desecrate the sanctuary of his God, for the consecration of the anointing oil of his God is on him; I am the LORD.
21No descendant of the priest Aaron who has a defect is to come near to present the fire offerings to the LORD. He has a defect and is not to come near to present the food of his God.
23But because he has a defect, he must not go near the curtain or approach the altar. He is not to desecrate my holy places, for I am the LORD who sets them apart."
