Luke 11:14-18

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 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.
