2 Kings 20:20

20 aThe rest of the deeds of Hezekiah and all his might and how he made bthe pool and the conduit cand brought water into the city, are they not written in the Book of the Chronicles of the Kings of Judah?

Isaiah 22:8-11

8He has taken away dthe covering of Judah.
In that day you looked to ethe weapons of the House of the Forest,
9and you saw that fthe breaches of the city of David were many. gYou collected the waters of the lower pool, 10and you counted the houses of Jerusalem, and you broke down the houses to fortify the wall. 11 hYou made a reservoir between ithe two walls for the water of jthe old pool. But kyou did not look to him who did it, or see him who planned it long ago.
