Leviticus 18:19

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, beside the other in her life time.

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

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

21And thou shalt not let any of thy seed pass through the fire to Molech, neither shalt thou profane the name of thy God: I am the LORD.
