Leviticus 18:16-18

Revised Standard Version Catholic Edition

¹⁶ You shall not uncover the nakedness of your brother’s wife; she is your brother’s nakedness. ¹⁷ You shall not uncover the nakedness of a woman and of her daughter, and you shall not take her son’s daughter or her daughter’s daughter to uncover her nakedness; they are your^[a] near kinswomen; it is wickedness. ¹⁸ And you shall not take a woman as a rival wife to her sister, uncovering her nakedness while her sister is yet alive.
