Leviticus 20:9, 11, 12

“ ‘Anyone who curses their father or mother is to be put to death. Because they have cursed their father or mother, their blood will be on their own head.

“ ‘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.

“ ‘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.
