2 Chronicles 32:4, 30, 32

A great many people were gathered, and they stopped all the springs and the brook that flowed through the land, saying, “Why should the kings of Assyria come and find much water?”

This same Hezekiah closed the upper outlet of the waters of Gihon and directed them down to the west side of the city of David. And Hezekiah prospered in all his works.

Now the rest of the acts of Hezekiah and his good deeds, behold, they are written in the vision of Isaiah the prophet, the son of Amoz, in the Book of the Kings of Judah and Israel.
