If a man marries his sister, whether she is the daughter of his father or the daughter of his mother, and they see each other's nakedness, it is a disgrace. They shall be cut off in the sight of their people; he has uncovered his sister's nakedness and shall bear his iniquity.
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 hath uncovered his sister's nakedness; he shall bear his iniquity.
