Leviticus 21:7-9

7They are not to marry women who are defiled as prostitutes, or profane. Neither shall they marry women divorced from their husbands, for a kohen is holy to his God.

8Therefore you are to sanctify him, because he offers the bread of your God. He should be holy to you, for I, Adonai, who sanctifies you, am holy.

9“The daughter of any kohen, if she profanes herself by playing the prostitute, profanes her father. She is to be burned with fire.
