Acts 19:13-16

13 Then some of the itinerant Jewish exorcists undertook to pronounce the name of the Lord Jesus over those who had evil spirits, saying, "I adjure you by the Jesus whom Paul preaches."
14 Seven sons of a Jewish high priest named Sceva were doing this.
15 But the evil spirit answered them, "Jesus I know, and Paul I know; but who are you?"
16 And the man in whom the evil spirit was leaped on them, mastered all of them, and overpowered them, so that they fled out of that house naked and wounded.
