Luke 11:17–20

17 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. 18 If Satan also be divided against himself, how shall his kingdom stand? because ye say that I cast out devils through Beelzebub. 19 And if I by Beelzebub cast out devils, by whom do your sons cast them out? therefore shall they be your judges. 20 But if I with the finger of God cast out devils, no doubt the kingdom of God is come upon you.
