Luke 11:21 (KJV)

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.

But when a stronger than he shall come upon him, and overcome him, he taketh from him all his armour wherein he trusted, and divideth his spoils.

He that is not with me is against me: and he that gathereth not with me scattereth.

When the unclean spirit is gone out of a man, he walketh through dry places, seeking rest; and finding none, he saith, I will return unto my house whence I came out.

And when he cometh, he findeth it swept and garnished.

Then goeth he, and taketh to him seven other spirits more wicked than himself; and they enter in, and dwell there: and the last state of that man is worse than the first.
