Leviticus 18:20

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 neighbor's wife, to defile thyself with her.

²¹  And 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.

²²  Thou shalt not lie with mankind, as with womankind: it is abomination.
