Acts 19:13-20

13And certain of the Jewish exorcists also, who went about, took in hand to call upon those who had wicked spirits the name of the Lord Jesus, saying, I adjure you by Jesus, whom Paul preaches.

14And there were certain [men], seven sons of Sceva, Jewish high priest, who were doing this.

15But the wicked spirit answering said to them, Jesus I know, and Paul I am acquainted with; but ye, who are ye?

16And the man in whom the wicked spirit was leaped upon them, and having mastered both, prevailed against them, so that they fled out of that house naked and wounded.

17And this became known to all, both Jews and Greeks, who inhabited Ephesus, and fear fell upon all of them, and the name of the Lord Jesus was magnified.

18And many of those that believed came confessing and declaring their deeds.

19And many of those that practised curious arts brought their books [of charms] and burnt them before all. And they reckoned up the prices of them, and found it fifty thousand pieces of silver.

20Thus with might the word of the Lord increased and prevailed.
