9 “‘As for the nakedness of your sister, the daughter of your father or the daughter of your mother, whether born in the same household or born outside it, you must not lay bare their nakedness.+

17 “‘And where a man takes his sister, the daughter of his father or the daughter of his mother, and he does see her nakedness, and she herself sees his nakedness, it is shame.+ So they must be cut off before the eyes of the sons of their people. It is the nakedness of his sister that he has laid bare. He should answer for his error.
