Sceva

Sceva - an implement, a Jew, chief of the priests at Ephesus (Acts 19:13-16); i.e., the head of one of the twenty-four courses of the house of Levi. He had seven sons, who "took upon them to call over them which had evil spirits the name of the Lord Jesus," in imitation of Paul. They tried their method of exorcism on a fierce demoniac, and failed. His answer to them was to this effect (19:15): "The Jesus whom you invoke is One whose authority I acknowledge; and the Paul whom you name I recognize to be a servant or messenger of God; but what sort of men are ye who have been empowered to act as you do by neither?" (Lindsay on the Acts of the Apostles.)
