Luke 11:18 YLT

¹⁶  and others, tempting, a sign out of heaven from him were asking.

¹⁷  And he, knowing their thoughts, said to them, 'Every kingdom having been divided against itself is desolated; and house against house doth fall;

¹⁸  and if also the Adversary against himself was divided, how shall his kingdom be made to stand? for ye say, by Beelzeboul is my casting forth the demons.

¹⁹  'But if I by Beelzeboul cast forth the demons -- your sons, by whom do they cast forth? because of this your judges they shall be;

²⁰  but if by the finger of God I cast forth the demons, then come unawares upon you did the reign of God.
