Ophel
    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.
