Leviticus 21:7-15

21:7 They must not take a wife defiled by prostitution, nor are they to take a wife divorced from her husband, for the priest is holy to his God. 21:8 You must sanctify him because he presents the food of your God. He must be holy to you because I, the Lord who sanctifies you all, am holy. 21:9 If a daughter of a priest profanes herself by engaging in prostitution, she is profaning her father. She must be burned to death.

Rules for the High Priest

21:10 “‘The high priest – who is greater than his brothers, on whose head the anointing oil is poured, who has been ordained to wear the priestly garments – must neither dishevel the hair of his head nor tear his garments. 21:11 He must not go where there is any dead person; he must not defile himself even for his father and his mother. 21:12 He must not go out from the sanctuary and must not profane the sanctuary of his God, because the dedication of the anointing oil of his God is on him. I am the Lord. 21:13 He must take a wife who is a virgin. 21:14 He must not marry a widow, a divorced woman, or one profaned by prostitution; he may only take a virgin from his people as a wife. 21:15 He must not profane his children among his people, for I am the Lord who sanctifies him.’”
