Leviticus 20:17-21 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 shameful thing; and they shall be cut off in the sight of the children of their people: he hath uncovered his sister's nakedness; he shall bear his iniquity.
