Leviticus 18:19
18. Neither shalt thou take a wife to her sister, to vex her, to uncover her nakedness, beside the other in her life time.19. Also thou shalt not approach unto a woman to uncover her nakedness, as long as she is put apart for her uncleanness.20. Moreover thou shalt not lie carnally with thy neighbour's wife, to defile thyself with her.
