Leviticus Chapter 18 World English Bible
You shall not do as they do in the land of Egypt, where you lived: and you shall not do as they do in the land of Canaan, where I am bringing you; neither shall you walk in their statutes.
"'You shall not uncover the nakedness of a woman and her daughter. You shall not take her son's daughter, or her daughter's daughter, to uncover her nakedness; they are near kinswomen: it is wickedness.
Therefore you shall keep my charge, that you do not practice any of these abominable customs, which were practiced before you, and that you do not defile yourselves with them: I am Yahweh your God.'"
