Then Jehoram passed over with his captains, and all his chariots with him: and he rose up by night, and smote the Edomites that compassed him about, and the captains of the chariots.

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 compassed Ophel about with it , and raised it up to a very great height: and he put valiant captains in all the fortified cities of Judah.
