Acts 19:11-20 - Would-Be Exorcists
11 And God performed unusual miracles by the hands of Paul, 12 so that napkins and aprons were brought from him to the sick, and their diseases left them, and the evil spirits went out of them.
13 And some of the travelling Jewish exorcists undertook to call over those that had evil spirits the name of the Lord Jesus, saying, I adjure you by the Jesus whom Paul preaches. 14 And there were some seven sons of Sceva, a Jew, a chief priest, who did this. 15 But the evil spirit answered and said, Jesus I know, and Paul I know, but who are you? 16 And the man in whom the evil spirit was leaped upon them, and overcome them, and prevailed against them, so that they escaped from his house, naked and wounded. 17 And this was known both to all the Jews and Greeks who lived at Ephesus, and fear fell on them all, and the name of the Lord Jesus was magnified; 18 and many of those who believed came and confessed, and showed their practices. 19 And many of those who practised secret arts brought their books, and burnt them before all; and they computed the price of them, and found it to be fifty thousand [didrachmas] of silver [$8,333]. 20 So the word of the Lord increased powerfully and prevailed.
