But let us consider the case of those whom the Lord so binds, going back to the words before the passage quoted, that we may understand it more clearly: The Jews were saying: “This man doth not cast out devils, but by Beelzebub, prince of the devils.” Jesus replied: “Every kingdom divided against itself shall be destroyed, and every city or house divided against itself shall not stand; for if Satan casteth out Satan, he is divided against himself, how then shall his kingdom stand? But if I cast out devils by Beelzebub, by whom do your sons cast them out?”
