2 Chronicles 32:5 MSG

[5] Hezekiah also went to work repairing every part of the city wall that was damaged, built defensive towers on it, built another wall of defense further out, and reinforced the defensive rampart (the Millo) of the old City of David. He also built up a large store of armaments—spears and shields. He then appointed military officers to be responsible for the people and got them all together at the public square in front of the city gate.
