Leviticus 21:10-15 - Rules For The High Priest

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. ¹¹ He must not go near any dead bodies or become unclean, even for his father or mother. ¹² He 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 Jehovah.

¹³ The anointed priest should marry a virgin. ¹⁴ He must not 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. ¹⁵ He must not dishonor his children among his people because I, Jehovah, set him apart as holy.
