2 Chronicles 32:2-4

2 When Hezekiah saw that Sennacherib had come to wage war against Jerusalem,

3 he, his officers, and his military staff made plans to stop the water from flowing out of the springs outside the city. They helped him do it.

4 A large crowd gathered as they stopped all the springs and the brook that flowed through the land. They said, "Why should the kings of Assyria find plenty of water?"
