Leviticus 21:11-15

¹¹He may not go near any dead body or make himself unclean for his father or his mother;

¹²He may not go out of the holy place or make the holy place of his God common; for the crown of the holy oil of his God is on him: I am the Lord.

¹³And let him take as his wife one who has not had relations with a man.

¹⁴A widow, or one whose husband has put her away, or a common woman of loose behaviour, may not be the wife of a priest; but let him take a virgin from among his people.

¹⁵And he may not make his seed unclean among his people, for I the Lord have made him holy.
