Leviticus 20:10-12

¹⁰‘If there is a man who commits adultery with another man’s wife, one who commits adultery with his friend’s wife, the adulterer and the adulteress shall surely be put to death. ¹¹If there is a man who lies with his father’s wife, he has uncovered his father’s nakedness; both of them shall surely be put to death, their bloodguiltiness is upon them. ¹²If there is a man who lies with his daughter-in-law, both of them shall surely be put to death; they have committed incest, their bloodguiltiness is upon them.
