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. ¹⁸ And you shall not take^[c] a woman as a rival to her sister, uncovering her nakedness while her sister is still alive.
