He built the Upper Gate of the house of the LORD, and he carried out considerable work on the wall of Ophel.

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.
