Acts 19:13-17

13 Some itinerant Jewish exorcists who happened to be in town at the time tried their hand at what they assumed to be Paul's "game." They pronounced the name of the Master Jesus over victims of evil spirits, saying, "I command you by the Jesus preached by Paul!"

14 The seven sons of a certain Sceva, a Jewish high priest, were trying to do this on a man

15 when the evil spirit talked back: "I know Jesus and I've heard of Paul, but who are you?"

16 Then the possessed man went berserk - jumped the exorcists, beat them up, and tore off their clothes. Naked and bloody, they got away as best they could.

17 It was soon news all over Ephesus among both Jews and Greeks. The realization spread that God was in and behind this. Curiosity about Paul developed into reverence for the Master Jesus.
