Leviticus 21:12-24

12 He shall not go outside the sanctuary and thus profane the sanctuary of his God; for the consecration of the anointing oil of his God is upon him: I am the Lord.
13 He shall marry only a woman who is a virgin.
14 A widow, or a divorced woman, or a woman who has been defiled, a prostitute, these he shall not marry. He shall marry a virgin of his own kin,
15 that he may not profane his offspring among his kin; for I am the Lord; I sanctify him.
16 The Lord spoke to Moses, saying:
17 Speak to Aaron and say: No one of your offspring throughout their generations who has a blemish may approach to offer the food of his God.
18 For no one who has a blemish shall draw near, one who is blind or lame, or one who has a mutilated face or a limb too long,
19 or one who has a broken foot or a broken hand,
20 or a hunchback, or a dwarf, or a man with a blemish in his eyes or an itching disease or scabs or crushed testicles.
21 No descendant of Aaron the priest who has a blemish shall come near to offer the Lord's offerings by fire; since he has a blemish, he shall not come near to offer the food of his God.
22 He may eat the food of his God, of the most holy as well as of the holy.
23 But he shall not come near the curtain or approach the altar, because he has a blemish, that he may not profane my sanctuaries; for I am the Lord; I sanctify them.
24 Thus Moses spoke to Aaron and to his sons and to all the people of Israel.
