Horeb
    desert or mountain of the dried-up ground, a general name for
    the whole mountain range of which Sinai was one of the summits
    (Ex. 3:1; 17:6; 33:6; Ps. 106:19, etc.). The modern name of the
    whole range is Jebel Musa. It is a huge mountain block, about 2
    miles long by about 1 in breadth, with a very spacious plain at
    its north-east end, called the Er Rahah, in which the Israelites
    encamped for nearly a whole year. (See SINAI.)
