Leviticus 21:12-14 New American Standard Bible (NASB)

12. nor shall he go out of the sanctuary nor profane the sanctuary of his God, for the consecration of the anointing oil of his God is on him; I am the Lord.

13. He shall take a wife in her virginity.

14. A widow, or a divorced woman, or one who is profaned by harlotry, these he may not take; but rather he is to marry a virgin of his own people,
