2 Kings 20:20

20:20 The rest of the events of Hezekiah’s reign and all his accomplishments, including how he built a pool and conduit to bring water into the city, are recorded in the scroll called the Annals of the Kings of Judah.

Isaiah 22:8-11

22:8 They removed the defenses of Judah.

At that time you looked

for the weapons in the House of the Forest.

22:9 You saw the many breaks

in the walls of the city of David;

you stored up water in the lower pool.

22:10 You counted the houses in Jerusalem,

and demolished houses so you could have material to reinforce the wall.

22:11 You made a reservoir between the two walls

for the water of the old pool –

but you did not trust in the one who made it;

you did not depend on the one who formed it long ago!
