The demons are subject to getting ejected in Luke11:14-23

And He was in the process of ejecting a demon, and it was one that rendered the one demonized unable to speak. And it came to pass that the demon having been ejected, the one who could not speak broke his silence and uttered words. And the crowds marvelled. But certain ones from among them said, By means of Beezeboul, the ruler of the demons, he is ejecting the demons. And others putting Him to the test kept on demanding an attesting miracle out of heaven from Him. But He himself, knowing their thoughts and the intents and purposes back of them, said to them, Every kingdom having been divided against itself in opposing factions is reduced to a state of ruin, and a home divided against itself in opposing factions, falls. Moreover, assuming also that Satan was divided against himself, how is it possible that his kingdom shall be made to stand, because you are saying that by means of Beezeboul I am ejecting the demons? But, as for myself, assuming for the moment that by means of Beezeboul I am ejecting the demons, your sons, by whom are they ejecting them? Upon this basis they themselves shall be your critics. But since by means of the finger of God, I, in contradistinction to them, am actually ejecting the demons, accordingly the kingdom of God came upon you sooner than you expected. When the strong man, having fully armed himself from head to foot, is guarding his own homestead, his possessions are safe. But when a stronger man than he having come upon him, overcomes him, he takes away his complete armor [shield, sword, lance, helmet, greaves, and breastplate] upon which he had fully placed his confidence, and distributes among others his booty. He who is not with me is against me. And he who is not gathering with me, is scattering.
