Leviticus 21:13-17

He shall take a wife in her virginity.

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

so that he will not profane his children among his people; for I am the Lord who sanctifies him.’ ”

Then the Lord spoke to Moses, saying,

“Speak to Aaron, saying, ‘None of your descendants throughout their generations who has an impairment shall approach to offer the food of his God.
