1Then the LORD said to Moses, “Speak to Aaron’s sons, the priests, and tell them that a priest is not to defile himself for a dead person among his people,
6They must be holy to their God and not profane the name of their God. Because they present to the LORD the offerings made by fire, the food of their God, they must be holy.
10The priest who is highest among his brothers, who has had the anointing oil poured on his head and has been ordained to wear the priestly garments, must not let his hair hang loose or tear his garments.
21No descendant of Aaron the priest who has a defect shall approach to present the offerings made by fire to the LORD. Since he has a defect, he is not to come near to offer the food of his God.
23but because he has a defect, he must not go near the veil or approach the altar, so as not to desecrate My sanctuaries. For I am the LORD who sanctifies them.’ ”
