Leviticus 20
17 Ref `And a man who taketh his sister, a daughter of his father or daughter of his mother, and he hath seen her nakedness, and she seeth his nakedness: it is a shame; and they have been cut off before the eyes of the sons of their people; the nakedness of his sister he hath uncovered; his iniquity he beareth.
18 Ref `And a man who lieth with a sick woman, and hath uncovered her nakedness, her fountain he hath made bare, and she hath uncovered the fountain of her blood, -- even both of them have been cut off from the midst of their people.
19 Ref `And the nakedness of thy mother's sister, and of thy father's sister, thou dost not uncover; because his relation he hath made bare; their iniquity they bear.
20 Ref `And a man who lieth with his aunt, the nakedness of his uncle he hath uncovered; their sin they bear; childless they die.
21 Ref `And a man who taketh his brother's wife -- it `is' impurity; the nakedness of his brother he hath uncovered; childless they are.
