Leviticus 21:7-8

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.

Leviticus 21:23

21:23 but he must not go into the veil-canopy or step forward to the altar because he has a physical flaw. Thus he must not profane my holy places, for I am the Lord who sanctifies them.’”
