2 Chronicles 32:3-5

New Catholic Bible

³ he suggested to his officers and warriors that they block up the springs of water that were outside the city, and they supported his plan. ⁴ Then a large number of people were summoned to block up all the springs, as well as the stream that flowed through that land, saying: “Why should the kings of Assyria come here and find an abundance of water?”

⁵ Hezekiah next concentrated on strengthening his defenses. He repaired every breach in the city wall that was broken down and raised towers upon it. Then he built another wall outside that first wall. He also strengthened the Millo of the City of David and gathered large numbers of weapons and shields.
