which commandment is adultery
Thou shalt not commit adultery, one of the Ten Commandments, is found at Exodus 20:14 of the Tanakh and Old Testament. What constitutes adultery is not defined in this passage of the Bible, and has been the subject of debate within Judaism and Christianity. Some Jewish sources (Chizkuni, Ibn Ezra) say that this commandment prohibits all sexually deviant acts, not only adultery.
