III. =Natural Features.= Edom is emphatically a land of mountains. On the west, along the side of the Arabah, is a line of low limestone hills. Back of these rise higher, igneous rocks, surmounted by variegated sandstone, of peculiar color, 2,000 feet high. The eastern side of the mountains slopes gently away into the Arabian desert. But, though rough, the land is rich, and the terraced hill-sides have in all ages been bright with vegetation, and its people have been prosperous. So the blessing of Esau (Gen. 27:39, 40) has been fulfilled in a land of "the fatness of the earth, and of the dew of heaven." Its capital during the Old Testament period was Bozrah (now _Busireh_), near its northern border. Afterward, Sela, the _Petra_ of remarkable rock-hewn buildings, arose to prominence. Ezion-geber, at the head of the Gulf of Akaba, was its seaport. IV. =History.= Mount Seir was first settled by the Horites, or Horim, like the inhabitants of Palestine a people of unknown origin. During the later patriarchal age it was conquered and possessed by Esau, the brother of Jacob, and ever after occupied by his descendants, the Edomites. The refusal of this people to allow the Israelites to journey through their territory compelled them to make a long detour around Edom on the south and east, and enter Palestine by the land of the Moabites. During the period of the Judges the Edomites are not mentioned; but they were beaten by Saul, and thoroughly conquered by David, after a severe struggle. At the division of the kingdom, B.C. 935, Edom was held by Judah. Its people rebelled in the time of Jehoram, the son of Jehoshaphat, and, although defeated by Judah, were able to maintain their independence. They joined the Chaldeans under Nebuchadnezzar in the destruction of Jerusalem, for which the later prophecies and psalms gave them bitter denunciations. About the time of the captivity, B.C. 587-536, the Edomites gained possession of most of the country south of Judah, extending even to the confines of Egypt. But they lost their own land, Mount Seir, which became the possession of the Nabatheans. These were a race, perhaps allied to the Arabians, who laid aside their nomad habits, and founded a kingdom, whose people grew rich by the caravan trade. The Edomites, or Idumeans, south of Palestine, were conquered by the Maccabean princes and incorporated with the Jews, B.C. 130, and the Nabathean kingdom was annexed to the Roman empire, A.D. 105.
