Acts 19:13-19

13Now there were some itinerant Jewish exorcists who tried to invoke the name of the Lord Jesus over those with evil spirits. They would say, “I command you by Jesus, whom Paul proclaims.” 14Seven sons of Sceva, a Jewish chief priest, were doing this.

15But one day the evil spirit responded, “Jesus I know, and I know about Paul, but who are you?” 16Then the man with the evil spirit jumped on them and overpowered them all. The attack was so violent that they ran out of the house naked and wounded.

17This became known to all the Jews and Greeks living in Ephesus, and fear came over all of them. So the name of the Lord Jesus was held in high honor. 18Many who had believed now came forward, confessing and disclosing their deeds. 19And a number of those who had practiced magic arts brought their books and burned them in front of everyone. When the value of the books was calculated, the total came to fifty thousand drachmas.1
