This same Hezekiah also stopped the upper spring of the waters of Gihon, and brought them straight down on the west side of the city of David. Hezekiah prospered in all his works.

Now after this he built an outer wall to the city of David, on the west side of Gihon, in the valley, even to the entrance at the fish gate; and he encircled Ophel [with it], and raised it up to a very great height: and he put valiant captains in all the fortified cities of Judah.
