Leviticus 21:12-15
12 nor leave the sanctuary of his God or desecrate it, because he has been dedicated by the anointing oil of his God. I am the Lord.
13 “‘The woman he marries must be a virgin.
14 He must not marry a widow, a divorced woman, or a woman defiled by prostitution, but only a virgin from his own people,
15 so he will not defile his offspring among his people. I am the Lord, who makes him holy.’”
