Imagine what it must have been like to see the armies of Babylon gathering outside the walls of Jerusalem? God had warned and warned, yet to no avail. The Babylonians were hardcore soldiers. They not only knew how to fight, defeat and slaughter their opponents, but they knew how to build siege ramps that allowed them to climb over any way. So even though Jerusalem was surrounded by a huge wall, Nebuchadnezzar's armies would gain access over it. So imagine how that felt to the people inside Jerusalem. Daily they heard the noise and saw the effort put in by Babylon's soldiers to build the ramp that would allow them to gain access to Jerusalem. Imagine the terror the people of Jerusalem felt.
