Acts 19:13-17

19:13 But some itinerant Jewish exorcists tried to invoke the name of the Lord Jesus over those who were possessed by evil spirits, saying, “I sternly warn you by Jesus whom Paul preaches.” 19:14 (Now seven sons of a man named Sceva, a Jewish high priest, were doing this.) 19:15 But the evil spirit replied to them, “I know about Jesus and I am acquainted with Paul, but who are you?” 19:16 Then the man who was possessed by the evil spirit jumped on them and beat them all into submission. He prevailed against them so that they fled from that house naked and wounded. 19:17 This became known to all who lived in Ephesus, both Jews and Greeks; fear came over them all, and the name of the Lord Jesus was praised.
