Leviticus 21:6-8

New Catholic Bible

⁶ They shall be holy to their God, and they are not to profane the name of their God, for they present offerings made by fire to the Lord, the food of their God. Therefore, they will be holy. ⁷ They are not to marry a prostitute or a woman who has been defiled, nor are they to marry a woman who has been divorced by her husband, for he is holy to his God.^{[a] 8} You shall therefore consecrate him, for he offers the bread of your God. He will be holy to you, for I, the Lord, who sanctify you, am holy.
