Luke 11:17-19

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.
