Luke 11:14-20

And he was casting out a devil, and it was dumb. And it came to pass, when the devil was gone out, the dumb spake; and the people wondered. But some of them said, He casteth out devils through Beelzebub the chief of the devils. 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 an 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.
