Leviticus 21:14-22
English Standard Version
Chapter 21
14A widow, or a divorced woman, or a woman who has been defiled, or a prostitute, these he shall not marry. But he shall take as his wife a virgin of his own people, 15that he may not profane his offspring among his people, for I am the Lord who sanctifies him."
16And the Lord spoke to Moses, saying,
17"Speak to Aaron, saying, None of your offspring throughout their generations who has a blemish may approach to offer the bread of his God.
18For no one who has a blemish shall draw near, a man blind or lame, or one who has a mutilated face or a limb too long,
19or a man who has an injured foot or an injured hand,
20or a hunchback or a dwarf or a man with a defect in his sight or an itching disease or scabs or crushed testicles.
21No man of the offspring of Aaron the priest who has a blemish shall come near to offer the Lord 's food offerings; since he has a blemish, he shall not come near to offer the bread of his God.
22He may eat the bread of his God, both of the most holy and of the holy things,
