2 Chronicles 32:2-4

2 When Hezekiah observed that Sennacherib had come and that he turned to war against Jerusalem,

3 he consulted with his officials and military men to stop up the waters of the springs that were outside the city, and they helped in this.

4 So, many people assembled and worked to stop up all the springs and the stream flowing through the area. They reasoned, “Why should the king of Assyria come and find a great amount of water?”
