Rekem is an ancient name for Petra and appears in Dead Sea scrolls such as 4Q462 associated with Mount Seir. Additionally, Eusebius and Jerome (Onom. sacr. 286, 71. 145, 9; 228, 55. 287, 94) assert that Rekem was the native name of Petra, supposedly on the authority of Josephus (Antiquities iv. 7, 1~ 4, 7), Pliny the Elder and other writers identify Petra as the capital of the Nabataeans, Aramaic-speaking Semites, and the centre of their caravan trade. Enclosed by towering rocks and watered by a perennial stream, Petra not only possessed the advantages of a fortress but controlled the main commercial routes which passed through it to Gaza in the west, to Bosra and Damascus in the north, to Aqaba and Leuce Come on the Red Sea, and across the desert to the Persian Gulf.
