“‘You shall not uncover the nakedness of your daughter-in-law. She is your son’s wife. You shall not uncover her nakedness.

“‘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.

“‘You shall not take a wife in addition to her sister, to be a rival, to uncover her nakedness, while her sister is still alive.

“‘You shall not approach a woman to uncover her nakedness, as long as she is impure by her uncleanness.
