Acts 19:11-20 - Would-Be Exorcists
11 And God wrought by the hands of Paul extraordinary miracles; 12 so that even from his skin there were brought handkerchiefs and aprons unto the diseased, and their disorders were chased from them, and the evil spirits came out of them.
13 Then certain of the Jews, who went about as exorcists, attempted to make mention of the name of the Lord Jesus over those who had evil spirits, saying, We adjure you by Jesus whom Paul preacheth. 14 And they were seven sons of Sceva a Jew, a chief priest, who did this. 15 Then the evil spirit replied, Jesus I know, and Paul I know; but who are ye? 16 And the man sprang upon them, in whom was the evil spirit, and getting the mastery over them, prevailed against them, so that they fled out of that house naked and wounded. 17 And this was known to all, both Jews and Greeks, who dwelt at Ephesus: and fear fell on them all, and they magnified the name of the Lord. 18 And many of those who believed came, confessing and declaring their practices. 19 And many of those who practised magical arts brought the books, and burned them before all men; and they calculated the prices of them, and found them worth fifty thousand pieces of silver. 20 So mightily did the word of God increase and prevail.
