Leviticus 21:6-8

New Century Version

⁶ They must be holy to their God and show respect for God’s name, because they present the offerings made by fire to the Lord, which is the food of their God. So they must be holy.

⁷ “‘A priest must not marry an unclean prostitute or a divorced woman, because he is holy to his God. ⁸ Treat him as holy, because he offers up the food of your God. Think of him as holy; I am the Lord who makes you holy, and I am holy.
