Luke 11:10
If Jesus casts out demons by Beelzebul, by whom do the Pharisees' own exorcists cast them out? The rhetorical question turns the accusation on the accusers: their own tradition of exorcism, which they consider legitimate, would be equally implicated by the Beelzebul charge. But if Jesus casts out demons by the finger of God, then the kingdom of God has come upon you — the exorcisms are not evidence against Jesus but evidence of the kingdom's arrival.
