Leviticus 20:11-13

11“ ‘If a man has sexual relations with his father’s wife, he has dishonored his father. Both the man and the woman are to be put to death; their blood will be on their own heads. 12“ ‘If a man has sexual relations with his daughter-in-law, both of them are to be put to death. What they have done is a perversion; their blood will be on their own heads. 13“ ‘If a man has sexual relations with a man as one does with a woman, both of them have done what is detestable. They are to be put to death; their blood will be on their own heads.
