Leviticus 18:20

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

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

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.

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