And if Satan cast out Satan,.... That is, if Satan, the same with Beelzebub, casts out the rest of the Satans, or other devils, of which he is the prince and head,he is divided against himself; he acts contrary to his own interest, which is to keep possession of the bodies and souls of men; and consequently it must, in course, be subversive of his power and dominion:how shall then his kingdom stand?
he will never be able to maintain his authority, and keep up the show of a government, as he does: for these words suggest, that there is a form of government among the devils, who are united in one body, under one head; and whose unity and concord are their greatest strength, as in all other governments.
