2 Chronicles 32:1-4

After Hezekiah’s faithful deeds, King Sennacherib of Assyria came and entered Judah. He laid siege to the fortified cities and intended  to break into them.  Hezekiah saw that Sennacherib had come and that he planned  war on Jerusalem, so he consulted with his officials and his warriors about stopping up the water of the springs that were outside the city, and they helped him. Many people gathered and stopped up all the springs  and the stream that flowed through the land;  they said, “Why should the kings of Assyria come and find abundant water? ”
