Leviticus 21:1-9

1And the Lord said to Moses, "Speak to the priests, the sons of Aaron, and say to them, No one shall make himself unclean for the dead among his people,

2except for his closest relatives, his mother, his father, his son, his daughter, his brother,

3or his virgin sister (who is near to him because she has had no husband; for her he may make himself unclean).

4He shall not make himself unclean as a husband among his people and so profane himself.

5They shall not make bald patches on their heads, nor shave off the edges of their beards, nor make any cuts on their body.

6They shall be holy to their God and not profane the name of their God. For they offer the Lord's food offerings, the bread of their God; therefore they shall be holy.

7They shall not marry a prostitute or a woman who has been defiled, neither shall they marry a woman divorced from her husband, for the priest is holy to his God.

8You shall sanctify him, for he offers the bread of your God. He shall be holy to you, for I, the Lord, who sanctify you, am holy.

9And the daughter of any priest, if she profanes herself by whoring, profanes her father; she shall be burned with fire.
