Leviticus 21:7-9

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.
