Leviticus 20:10-12

¹⁰And the man that committeth adultery with another man's wife, even he that committeth adultery with his neighbor's wife, the adulterer and the adulteress shall surely be put to death.

¹¹And the man that lieth with his father's wife hath uncovered his father's nakedness; both of them shall surely be put to death: their blood shall be upon them.

¹²And if a man shall lie with his daughter-in-law, both of them shall surely be put to death: they have wrought confusion; their blood shall be upon them.
