Leviticus 20:17-21

Revised Standard Version

¹⁷ “If a man takes his sister, a daughter of his father or a daughter of his mother, and sees her nakedness, and she sees his nakedness, it is a shameful thing, and they shall be cut off in the sight of the children of their people; he has uncovered his sister’s nakedness, he shall bear his iniquity. 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. ²¹ If a man takes his brother’s wife, it is impurity; he has uncovered his brother’s nakedness, they shall be childless.
