New Defender's Study Bible Notes
19:13 exorcists. The city of Ephesus was notorious in the ancient world not only for its idols but also for an abundance of magicians and other occultists. Demon possession was common and, therefore, there were also the practitioners of exorcism. The “wandering Jews,” who professed to be able to invoke the supposedly unpronounceable name of the Lord over those possessed, were among them. The seven sons of Sceva (who professed to be a chief priest), were not Christians, but they saw that Paul had been more effective than other exorcists in casting out demons, and so decided that the name of Jesus was itself strong magic.
