Leviticus 20:18-20

New Revised Standard Version, Anglicised

¹⁸ If a man lies with a woman having her sickness and uncovers her nakedness, he has laid bare her flow and she has laid bare her flow of blood; both of them shall be cut off from their people. ¹⁹ You shall not uncover the nakedness of your mother’s sister or of your father’s sister, for that is to lay bare one’s own flesh; they shall be subject to punishment. ²⁰ If a man lies with his uncle’s wife, he has uncovered his uncle’s nakedness; they shall be subject to punishment; they shall die childless.
