Luke 11:14-20

And he was casting out a demon that was dumb. And it came to pass, when the demon was gone out, the dumb man spake; and the multitudes marvelled. But some of them said, By Beelzebub the prince of the demons casteth he out demons. And others, trying 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. And if Satan also is divided against himself, how shall his kingdom stand? because ye say that I cast out demons by 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 by the finger of God cast out demons, then is the kingdom of God come upon you.
