Leviticus 21:7-9

Living Bible

⁷ A priest shall not marry a prostitute, nor a woman of another tribe, and he shall not marry a divorced woman, for he is a holy man of God. ⁸ The priest is set apart to offer the sacrifices of your God; he is holy, for I, the Lord who sanctifies you, am holy. ⁹ The daughter of any priest who becomes a prostitute, thus violating her father’s holiness as well as her own, shall be burned alive.
