The Bible
Leviticus 21
The priests are to be holy—The high priest is not to marry a widow, a divorced person, or a harlot—Descendants of Aaron with physical blemishes may not offer the bread of God upon the altar.
4But he shall not defile himself, being a chief man among his people, to profane himself.
11Neither shall he go in to any dead body, nor defile himself for his father, or for his mother;
13And he shall take a wife in her virginity.
15Neither shall he profane his seed among his people: for I the Lord do sanctify him.
16¶ And the Lord spake unto Moses, saying,
19Or a man that is brokenfooted, or brokenhanded,
22He shall eat the bread of his God, both of the most holy, and of the holy.
24And Moses told it unto Aaron, and to his sons, and unto all the children of Israel.
