Leviticus 21:6-8

New Revised Standard Version, Anglicised Catholic Edition

⁶ They shall be holy to their God, and not profane the name of their God; for they offer the Lord’s offerings by fire, the food of their God; therefore they shall be holy. 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.
