Isaiah 7:3

7:3 So the Lord told Isaiah, “Go out with your son Shear-jashub and meet Ahaz at the end of the conduit of the upper pool which is located on the road to the field where they wash and dry cloth.

Isaiah 22:9-11

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!
