Leviticus 18:15-20

¹⁶Thou shalt not uncover the nakedness of thy brother's wife: it is 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; for they are her near kinswomen: it is wickedness.

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

¹⁹Also thou shalt not approach to a woman to uncover her nakedness, as long as she is put apart for her uncleanness.

²⁰Moreover, thou shalt not lie carnally with thy neighbor's wife, to defile thyself with her.
