Leviticus 21:7-9

7A priest must not marry a woman who has left her husband. He must not marry a woman if men have paid her to have sex with her. He must not marry a woman whose husband has sent her away. A priest must be holy.

8A priest is holy because he sacrifices the people's offerings to God. A priest is holy because I, the Lord, am holy.

9A priest's daughter must not have sex with men who pay her. That would make her unclean. She would take away her father's honour. If she does not obey, you must burn her in a fire.
