'Cast Out Demons' in the Bible

If Satan also be divided against himself, how shall his kingdom stand? because you say that I cast out demons through Beelzebub.

And if I by Beelzebub cast out demons, by whom do your sons cast them out? therefore shall they be your judges.

But if I with the finger of God cast out demons, no doubt the kingdom of God is come upon you.

And he said unto them, Go, and tell that fox, Behold, I cast out demons, and I perform cures today and tomorrow, and the third day I shall be finished.
