Acts 19:10-20

10 And this happened for two years so that all those dwelling in Asia did hear the word of the Lord Jesus, both Jews and Greeks,
11 mighty works also -- not common -- was God working through the hands of Paul,
12 so that even unto the ailing were brought from his body handkerchiefs or aprons, and the sicknesses departed from them; the evil spirits also went forth from them.
13 And certain of the wandering exorcist Jews, took upon [them] to name over those having the evil spirits the name of the Lord Jesus, saying, `We adjure you by Jesus, whom Paul doth preach;'
14 and there were certain -- seven sons of Sceva, a Jew, a chief priest -- who are doing this thing;
15 and the evil spirit, answering, said, `Jesus I know, and Paul I am acquainted with; and ye -- who are ye?'
16 And the man, in whom was the evil spirit, leaping upon them, and having overcome them, prevailed against them, so that naked and wounded they did flee out of that house,
17 and this became known to all, both Jews and Greeks, who are dwelling at Ephesus, and fear fell upon them all, and the name of the Lord Jesus was being magnified,
18 many also of those who did believe were coming, confessing and declaring their acts,
19 and many of those who had practised the curious arts, having brought the books together, were burning [them] before all; and they reckoned together the prices of them, and found [it] five myriads of silverlings;
20 so powerfully was the word of God increasing and prevailing.
