Hill; mound, the long, narrow, rounded promontory on the southern slope of the temple hill, between the Tyropoeon and the Kedron valley (2 Chr. 27:3; 33:14; Neh. 3:26, 27). It was surrounded by a separate wall, and was occupied by the Nethinim after the Captivity. This wall has been discovered by the engineers of the Palestine Exploration Fund at the south-eastern angle of the temple area. It is 4 feet below the present surface. In 2 Kings 5:24 this word is translated “tower” (R.V., “hill”), denoting probably some eminence near Elisha’s house.
Ophel
Ophel was a part of Jerusalem, and the Bible mostly mentions it when walls were being built. Of Jotham it says, “on the wall of Ophel he built much” (2 Chronicles 27:3). Later Manasseh “compassed about Ophel, and raised it up a very great height” (33:14). In Nehemiah 3, after the exile, the Nethinims dwell in Ophel and the Tekoites repair a piece of wall “unto the wall of Ophel.” Nehemiah 3 reads like a roll call of the people rebuilding their city.
