Jesus knew their thoughts and said to them, “Any kingdom divided against itself will be ruined, and a house divided against itself will fall. If Satan is divided against himself, how can his kingdom stand? I say this because you claim that I drive out demons by Beelzebul. Now if I drive out demons by Beelzebul, by whom do your followers drive them out? So then, they will be your judges. But if I drive out demons by the finger of God, then the kingdom of God has come upon you.

When a strong man, fully armed, guards his own house, his possessions are safe. But when someone stronger attacks and overpowers him, he takes away the armour in which the man trusted and divides up the spoils. Whoever is not with me is against me, and whoever does not gather with me scatters.” - Luke 11: 17-23
