Luke 11:18

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.

Luke 11:18 Meaning and Commentary

Luke 11:18

And if Satan also be divided against himself, how shall
his kingdom stand?
&c.] This is the accommodation of the above parables, or proverbial sentences; suggesting, that Satan must be against himself, if what the Pharisees said was true; and consequently, his kingdom and government, could not long subsist:

because ye say that I cast out devils through Beelzebub;
which is all one as to say, that Satan is divided against himself, which is not reasonable to suppose; (See Gill on Matthew 12:26) and (See Gill on Mark 3:26).

Luke 11:18 In-Context

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.
