Acts 19:13-16

13Then some of the itinerant Jewish exorcists undertook to invoke the name of the Lord Jesus over those who had evil spirits, saying, "I adjure you by the Jesus whom Paul proclaims."

14Seven sons of a Jewish high priest named Sceva were doing this.

15But the evil spirit answered them, "Jesus I know, and Paul I recognize, but who are you?"

16And the man in whom was the evil spirit leaped on them, mastered all of them and overpowered them, so that they fled out of that house naked and wounded.
