Leviticus 21:14

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

12 neither 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 Jehovah.

13 And he shall take a wife in her virginity.

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

15 And he shall not profane his seed among his people: for I am Jehovah who sanctifieth him.

16 And Jehovah spake unto Moses, saying,

17 Speak unto Aaron, saying, Whosoever he be of thy seed throughout their generations that hath a blemish, let him not approach to offer the bread of his God.
