De 9:1-25. MOSES DISSUADES THEM FROM THE OPINION OF THEIR OWN RIGHTEOUSNESS.

      1. this day--means this time. The Israelites had reached the confines of the promised land, but were obliged, to their great mortification, to return. But now they certainly were to enter it. No obstacle could prevent their possession; neither the fortified defenses of the towns, nor the resistance of the gigantic inhabitants of whom they had received from the spies so formidable a description.
      cities great and fenced up to heaven--Oriental cities generally cover a much greater space than those in Europe; for the houses often stand apart with gardens and fields intervening. They are almost all surrounded with walls built of burnt or sun-dried bricks, about forty feet in height. All classes in the East, but especially the nomad tribes, in their ignorance of engineering and artillery, would have abandoned in despair the idea of an assault on a walled town, which to-day would be demolished in a few hours.
