Leviticus 21:9-19

9 When the daughter of a priest profanes herself through prostitution, she profanes her father; she shall be burned to death.
10 The priest who is exalted above his fellows, on whose head the anointing oil has been poured and who has been consecrated to wear the vestments, shall not dishevel his hair, nor tear his vestments.
11 He shall not go where there is a dead body; he shall not defile himself even for his father or mother.
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,
