Leviticus 21:7-9

New Revised Standard Version Catholic Edition

⁷ They shall not marry a prostitute or a woman who has been defiled; neither shall they marry a woman divorced from her husband. For they are holy to their God, ⁸ and you shall treat them as holy, since they offer the food of your God; they shall be holy to you, for I the Lord, I who sanctify you, am holy. ⁹ When the daughter of a priest profanes herself through prostitution, she profanes her father; she shall be burned to death.
