Leviticus 20:10-11

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

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