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.)
