Acts 19:13-20

Then some of the traveling Jewish exorcists also attempted to call the name of the Lord Jesus over those who had evil spirits, saying, “I implore you and solemnly command you by the Jesus whom Paul preaches!” Seven sons of one [named] Sceva, a Jewish chief priest, were doing this. But the evil spirit retorted, “I know and recognize and acknowledge Jesus, and I know about Paul, but as for you, who are you?” Then the man, in whom was the evil spirit, leaped on them and subdued all of them and overpowered them, so that they ran out of that house [in terror, stripped] naked and wounded. This became known to all who lived in Ephesus, both Jews and Greeks. And fear fell upon them all, and the name of the Lord Jesus was magnified and exalted. Many of those who had become believers were coming, confessing and disclosing their [former sinful] practices. And many of those who had practiced magical arts collected their books and [throwing book after book on the pile] began burning them in front of everyone. They calculated their value and found it to be 50,000 pieces of silver. So the word of the Lord [concerning eternal salvation through faith in Christ] was growing greatly and prevailing.
