Leviticus 21:6-8

21:6 “‘They must be holy to their God, and they must not profane the name of their God, because they are the ones who present the Lord’s gifts, the food of their God. Therefore they must be holy. 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.
