2 Chronicles 32:4, 30, 32

So there was gathered much people together, who stopped all the fountains, and the brook that ran through the midst of the land, saying, Why should the kings of Assyria come, and find much water?

This same Hezekiah also stopped the upper watercourse of Gihon, and brought it straight 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 goodness, behold, they are written in the vision of Isaiah the prophet, the son of Amoz, and in the book of the kings of Judah and Israel.
