Matthew 14:2
And he said to his servants: this is John the Baptist. He has been raised from the dead; that is why miraculous powers are at work in him. Herod's guilty conscience produces the identification of Jesus with the resurrected John the Baptist. The superstitious fear that the man he killed has been raised from the dead communicates the haunting power of an unjust execution: Herod cannot escape the memory of John, and Jesus' fame renews the guilt. The miraculous powers at work in the resurrected John is Herod's explanation for what he cannot otherwise account for.
