Part of the flat country stretching from the Dead Sea to Tekoa, a waste table land in front of the valley; where Jahaziel told Jehoshaphat he should encounter Ammon, Moab, etc., pouring round the S. of the Dead Sea into Judah (2Ch 20:16,24); containing "the watchtower" built there for observing from afar such inroads. "The ascent of Ziz," or Hazziz, has probably given its name to the wady el Hasasah.
