Luke 11:15-19

15But some of them said, He casteth out demons through Beelzebub the chief of the demons.1 16And others, tempting him, sought from him a sign from heaven. 17But he, knowing their thoughts, said to them, Every kingdom divided against itself is brought to desolation; and a house divided against a house falleth. 18If Satan also is divided against himself, how shall his kingdom stand? because ye say that I cast out demons through Beelzebub. 19And if I by Beelzebub cast out demons, by whom do your sons cast them out? therefore shall they be your judges.
