Luke 11:18-20

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.
