'Cast Out Demons' in the Bible

If Satan also is divided against himself, how shall his kingdom stand? because ye 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 to them, Go ye and tell that fox, Behold, I cast out demons, and I do cures to-day and to-morrow, and the third day I shall be perfected.
