Leviticus 21:13 KJV

11Neither shall he go in to any dead body, nor defile himself for his father, or for his mother;

12Neither shall he go out of the sanctuary, nor profane the sanctuary of his God; for the crown of the anointing oil of his God is upon him: I am the LORD.

13And he shall take a wife in her virginity.

14A widow, or a divorced woman, or profane, or an harlot, these shall he not take: but he shall take a virgin of his own people to wife.

15Neither shall he profane his seed among his people: for I the LORD do sanctify him.
