Leviticus 18:16-20 English Standard Version (ESV)

16. You shall not uncover the nakedness of your brother’s wife; it is your brother’s nakedness.

17. You shall not uncover the nakedness of a woman and of her daughter, and you shall not take her son’s daughter or her daughter’s daughter to uncover her nakedness; they are relatives; it is depravity.

18. And you shall not take a woman as a rival wife to her sister, uncovering her nakedness while her sister is still alive.

19. “You shall not approach a woman to uncover her nakedness while she is in her menstrual uncleanness.

20. And you shall not lie sexually with your neighbor’s wife and so make yourself unclean with her.
