Poor Herod. The mighty king believes he controls life and death. Yet he is manipulated into murdering John the Baptist by two scheming women. Then his guilty conscience makes him think that Jesus is a resurrected John the Baptist, empowered by God to do great miracles.
Herod, you murderous, self-deceived old fox: keep your eye on this Jesus of Nazareth. If you're worried about a wrongfully-executed Jewish prophet coming back from the dead and doing such great wonders that your authority is threatened, YOU AIN'T SEEN NUTHIN' YET!
