The New John Gill Exposition of the Entire BibleLuke 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;
all one as to say, that Satan is divided against himself, which is
not reasonable to suppose; (See Gill on 12:26) and
(See Gill on 3:26).
