Luke 11:17

‘But he, knowing their thoughts, said to them, “Every kingship divided against itself is brought to desolation, and a house divided against a house falls (literally ‘house falls on house').” '

But Jesus knew what the majority of them were thinking and pointed out that if what they said was true it would mean that in that evil world which caused such harm there was division within the kingship, and civil war between the factions. They would be destroying each other, house against house. For they were claiming that He had authority over demons and was fighting against them with the connivance of the prince of demons. Such a situation would mean that the combatants could not survive. For division in a kingship always brought desolation, and a divided house always falls.
