Ophel

He built the upper gate of the LORD’s house, and on the wall of Ophel he built much.

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.

(Now the Nethinim lived in Ophel, to the place over against the water gate toward the east, and the tower that stands out.)

After him the Tekoites repaired another portion, over against the great tower that stands out, and to the wall of Ophel.

But the Nethinim lived in Ophel: and Ziha and Gishpa were over the Nethinim.
