Leviticus 20:18-20

Revised Standard Version

¹⁸ If a man lies with a woman having her sickness, and uncovers her nakedness, he has made naked her fountain, and she has uncovered the fountain of her blood; both of them shall be cut off from among their people. ¹⁹ You shall not uncover the nakedness of your mother’s sister or of your father’s sister, for that is to make naked one’s near kin; they shall bear their iniquity. ²⁰ If a man lies with his uncle’s wife, he has uncovered his uncle’s nakedness; they shall bear their sin, they shall die childless.
