Sela
     =Se'lah, rock, the capital of Edom, situated in the great valley
     extending from the Dead Sea to the Red Sea (2 Kings 14:7). It
     was near Mount Hor, close by the desert of Zin. It is called
     "the rock" (Judg. 1:36). When Amaziah took it he called it
     Joktheel (q.v.) It is mentioned by the prophets (Isa. 16:1;
     Obad. 1:3) as doomed to destruction.
       It appears in later history and in the Vulgate Version under
     the name of Petra. "The caravans from all ages, from the
     interior of Arabia and from the Gulf of Persia, from Hadramaut
     on the ocean, and even from Sabea or Yemen, appear to have
     pointed to Petra as a common centre; and from Petra the tide
     seems again to have branched out in every direction, to Egypt,
     Palestine, and Syria, through Arsinoe, Gaza, Tyre, Jerusalem,
     and Damascus, and by other routes, terminating at the
     Mediterranean." (See EDOM [2].)
