Leviticus 20
16 Ref `And a woman who draweth near unto any beast to lie with it -- thou hast even slain the woman and the beast; they are certainly put to death; their blood `is' on them.
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.
