Leviticus 20:10

10. And 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.

10. Vir qui adulterium commiserit cum uxore alterius, qui adulterium commiserit cum uxore proximi sui moriendo morientur adulter et adultera.
