What does Isaiah 22:10 mean?
Jerusalem had begun their preparations against an outside siege. This meant securing and distributing the weapons from their armory (Isaiah 22:8). Water had been redirected from springs outside the walls into the city to keep the enemy from depriving them of essential drinking water (Isaiah 22:9).Also, breaches in the walls were identified and patched with building material from houses that were torn down. It's possible these houses were removed from between the inner and outer walls of the city. This removal of the houses could have had two purposes. First, for the safety of the citizens, and secondly to flood that space as an extra obstacle to the enemy.
