Acts 19:11-20

And God wrought special miracles by the hands of Paul: insomuch that unto the sick were carried away from his body handkerchiefs or aprons, and the diseases departed from them, and the evil spirits went out. But certain also of the strolling Jews, exorcists, took upon them to name over them that had the evil spirits the name of the Lord Jesus, saying, I adjure you by Jesus whom Paul preacheth. And there were seven sons of one Sceva, a Jew, a chief priest, who did this. And the evil spirit answered and said unto them, Jesus I know, and Paul I know; but who are ye? And the man in whom the evil spirit was leaped on them, and mastered both of them, and prevailed against them, so that they fled out of that house naked and wounded. And this became known to all, both Jews and Greeks, that dwelt at Ephesus; and fear fell upon them all, and the name of the Lord Jesus was magnified. Many also of them that had believed came, confessing, and declaring their deeds. And not a few of them that practised magical arts brought their books together and burned them in the sight of all; and they counted the price of them, and found it fifty thousand pieces of silver. So mightily grew the word of the Lord and prevailed.
