Leviticus 18:16KJV

14Thou shalt not uncover the nakedness of thy father's brother, thou shalt not approach to his wife: she thine aunt.

15Thou shalt not uncover the nakedness of thy daughter in law: she thy son's wife; thou shalt not uncover her nakedness.

16Thou shalt not uncover the nakedness of thy brother's wife: it thy brother's nakedness.

17Thou shalt not uncover the nakedness of a woman and her daughter, neither shalt thou take her son's daughter, or her daughter's daughter, to uncover her nakedness; they her near kinswomen: it wickedness.

18Neither shalt thou take a wife to her sister, to vex , to uncover her nakedness, beside the other in her life .
