Leviticus 20:10-12

¹⁰'And a man who committeth adultery with a man's wife — who committeth adultery with the wife of his neighbour — the adulterer and the adulteress are surely put to death.

¹¹'And a man who lieth with his father's wife — the nakedness of his father he hath uncovered — both of them are certainly put to death; their blood is on them.

¹²'And a man who lieth with his daughter-in-law — both of them are certainly put to death; confusion they have made; their blood is on them.
