Leviticus 21:10-14

10“The priest who is anointed with oil and wears the chief priest’s clothes is chief over his brothers. He must never mourn by leaving his hair uncombed or by tearing his clothes.

11He must never go near any dead bodies or become unclean, even for his father or mother.

12He must not leave the holy tent of his God. If he does, he will be dishonoring it, because he is dedicated with the anointing oil of his God. I am the Lord.

13“The anointed priest must marry a virgin.

14He must never marry a widow, a divorced woman, a woman who has lost her virginity, or a prostitute. He may only marry a virgin from his own people.
