Luke 11:16-20

And others, tempting him, sought of him a sign from heaven.

But he, knowing their thoughts, said unto them, Every kingdom divided against itself is brought to desolation; and a house divided against a house falleth.

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

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

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