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
(Exodus 3:1; 17:6; 33:6; Psalms 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.
