[ A-2,Noun,G3428, moichalis ]
"an adulteress," is used
(a) in the natural sense, 2 Peter 2:14; Romans 7:3;
(b) in the spiritual sense, James 4:4; here the RV rightly omits the word "adulterers." It was added by a copyist. As in Israel the breach of their relationship with God through their idolatry, was described as "adultery" or "harlotry" (e.g., Ezekiel 16:15 ff.; Ezekiel 23:43), so believers who cultivate friendship with the world, thus breaking their spiritual union with Christ, are spiritual "adulteresses," having been spiritually united to Him as wife to husband, Romans 7:4. It is used adjectivally to describe the Jewish people in transferring their affections from God, Matthew 12:39; Matthew 16:4; Mark 8:38. In 2 Peter 2:14, the lit. translation is "full of an adulteress" (RV, marg.).
