You shall not uncover the nakedness of your sister, the daughter of your father or the daughter of your mother, born at home or born away. Their nakedness you shall not uncover.
And a man has done abomination with his neighbor's wife; and a man has defiled his daughter-in-law in unchaste acts; and a man has humbled within you his sister, his father's daughter.
And if a man shall take his sister, his father's daughter, or his mother's daughter, and see her nakedness, and she see his nakedness, it is a wicked thing. And they shall be cut off in the sight of their people. He has uncovered his sister's nakedness; he shall bear his iniquity.
