“‘You must not approach a woman in her menstrual impurity to have sexual intercourse with her.

“‘No man is to approach any close relative to have sexual intercourse with her. I am the Lord.

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.

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.
