Mount Esau -  Idumea (Isa 34:5 ,6; Ezek 35:15 ). “The field of Edom” (Gen 32:3 ), “the land of Edom” (Gen 36:16 ), was mountainous (Obad 1:8 ,9,19,21). It was called the land, or “the mountain of Seir,” the rough hills on the east side of the Arabah. It extended from the head of the Gulf of Akabah, the Elanitic gulf, to the foot of the Dead Sea (1Kings 9:26), and contained, among other cities, the rock-hewn Sela (q.v.), generally known by the Greek name Petra (2Kings 14:7). It is a wild and rugged region, traversed by fruitful valleys. Its old capital was Bozrah (Isa 63:1 ). The early inhabitants of the land were Horites. They were destroyed by the Edomites (Deut 2:12 ), between whom and the kings of Israel and Judah there was frequent war (2Kings 8:20;2Chr 28:17 ) EBD
