Every word of Scripture is important and we must live by every word that proceeds out of the mouth of God (Matt. 4:4). Cities and the countryside are both important and they need each other. Both can be good or bad places to live. Judah's land was divided into counties (mishpacha). Judah failed to drive the Philistines out of their coastal cities and the Jebusites out of Jerusalem. This was a failure of faith and action. We must not give Satan a foothold but drive the enemy out of our lives completely.
