Leviticus 21:10–12

“The priest who is chief among his brothers, on whose head the anointing oil is poured and who has been consecrated to wear the garments, shall not let the hair of his head hang loose nor tear his clothes. He shall not go in to any dead bodies nor make himself unclean, even for his father or for his mother. He shall not go out of the sanctuary, lest he profane the sanctuary of his God, for the consecration of the anointing oil of his God is on him: I am the Lord.

“ ‘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. He must not enter a place where there is a dead body. He must not make himself unclean, even for his father or mother, nor leave the sanctuary of his God or desecrate it, because he has been dedicated by the anointing oil of his God. I am the Lord.

“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. He must not go near any dead person or make himself unclean even for his father or mother. He 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.

“The high priest has the highest rank of all the priests. The anointing oil has been poured on his head, and he has been ordained to wear the priestly garments. He must never leave his hair uncombed or tear his clothing. He must not defile himself by going near a dead body. He may not make himself ceremonially unclean even for his father or mother. He must not defile the sanctuary of his God by leaving it to attend to a dead person, for he has been made holy by the anointing oil of his God. I am the Lord.

“ ‘As for the priest who is higher than his brothers, on whose head the oil of anointment is poured and he was ordained to wear the garments, he shall not dishevel his head, and he shall not tear his garments. And he shall not go near any dead person, nor shall he make himself unclean for his father or for his mother. And he shall not go out from the sanctuary, and he shall not profane his God’s sanctuary, because the dedication of his God’s oil of anointment is on him; I am Yahweh.

And he that is the high priest among his brethren, upon whose head the anointing oil was poured, and that is consecrated to put on the garments, shall not uncover his head, nor rend his clothes; Neither shall he go in to any dead body, nor defile himself for his father, or for his mother; Neither shall he go out of the sanctuary, nor profane the sanctuary of his God; for the crown of the anointing oil of his God is upon him: I am the Lord.
