2 Chronicles 32:2-4

2Now when Hezekiah saw that Sennacherib had come and that 1he intended to wage war against Jerusalem,

3he decided with his officers and his warriors to cut off the supply of water from the springs which were outside the city, and they helped him.

4So many people assembled 2and stopped up all the springs and 3the stream which flowed 4through the region, saying, “Why should the kings of Assyria come and find abundant water?”
