Leviticus 20:18-20

New Century Version

¹⁸ “‘If a man has sexual relations with a woman during her monthly period, both the woman and the man must be cut off from their people. They sinned because they showed the source of her blood.

¹⁹ “‘Do not have sexual relations with your mother’s sister or your father’s sister, because that would shame a close relative. Both of you are guilty of this sin.

²⁰ “‘If a man has sexual relations with his uncle’s wife, he has shamed his uncle. That man and his uncle’s wife will die without children; they are guilty of sin.
