Leviticus 18:15-17

New Revised Standard Version, Anglicised Catholic Edition

¹⁵ You shall not uncover the nakedness of your daughter-in-law: she is your son’s wife; you shall not uncover her nakedness. ¹⁶ You shall not uncover the nakedness of your brother’s wife; it is your brother’s nakedness. ¹⁷ You shall not uncover the nakedness of a woman and her daughter, and you shall not take^[a] her son’s daughter or her daughter’s daughter to uncover her nakedness; they are your^[b] flesh; it is depravity.
