Acts 19:13-16

13But certain also of the strolling Jews, exorcists, took upon them to name over them that had the evil spirits the name of the Lord Jesus, saying, I adjure you by Jesus whom Paul preacheth. 14And there were seven sons of one Sceva, a Jew, a chief priest, who did this. 15And the evil spirit answered and said unto them, Jesus I know, and Paul I know; but who are ye? 16And the man in whom the evil spirit was leaped on them, and mastered both of them, and prevailed against them, so that they fled out of that house naked and wounded.
