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. You shall not take her son’s daughter, or her daughter’s daughter, to uncover her nakedness. They are near kinswomen. It is wickedness.
