Leviticus 18:16-20

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

You shall not uncover the nakedness of a woman and of her daughter, nor shall you take her son’s daughter or her daughter’s daughter, to uncover her nakedness; they are blood relatives. It is an outrageous sin.

And you shall not marry a woman in addition to her sister as a second wife while she is alive, to uncover her nakedness.

‘Also you shall not approach a woman to uncover her nakedness during her menstrual impurity.

And you shall not have sexual intercourse with your neighbor’s wife, to be defiled with her.
