Leviticus 18:7-8; Leviticus 20:11

vYou shall not uncover the nakedness of your father, which is the nakedness of your mother; she is your mother, you shall not uncover her nakedness. wYou shall not uncover the nakedness of your father's wife; it is your father's nakedness.


11 cIf a man lies with his father's wife, he has uncovered his father's nakedness; both of them shall surely be put to death; their blood is upon them.
