Luke identifies Sceva as a Jewish high priest whose seven sons practiced exorcism in Ephesus (Acts 19:14). Their attempt to invoke Jesus's name over a demon-possessed man backfires spectacularly when the spirit responds, 'Jesus I know, and Paul I know, but who are you?' The demon-possessed man overpowers all seven, leaving them wounded and naked. The incident demonstrates that using Jesus's name like a magical formula, without genuine faith, is both powerless and dangerous. Sceva's designation as 'chief priest' is puzzling—perhaps a local synagogue leader or self-styled religious authority rather than Jerusalem's high priest.
