Leviticus 18:17-20

17You must not have sexual relations with both a woman and her daughter. You are not to marry her son’s daughter or her daughter’s daughter and have sexual relations with her. They are close relatives; it is depraved.

18You must not take your wife’s sister as a rival wife and have sexual relations with her while your wife is still alive.

19You must not approach a woman to have sexual relations with her during her menstrual period.

20You must not lie carnally with your neighbor’s wife and thus defile yourself with her.
