Leviticus 18:17-20

18:17 You must not have sexual intercourse with both a woman and her daughter; you must not take as wife either her son’s daughter or her daughter’s daughter to have intercourse with them. They are closely related to her – it is lewdness. 18:18 You must not take a woman in marriage and then marry her sister as a rival wife while she is still alive, to have sexual intercourse with her.

18:19 “‘You must not approach a woman in her menstrual impurity to have sexual intercourse with her. 18:20 You must not have sexual intercourse with the wife of your fellow citizen to become unclean with her.
