Carl Friedrich Keil and Franz Delitzsch Old Testament Commentary

The different portions of the conquered land were the following: המּישׁר, the plain, i.e., the Amoritish table-land, stretching from the Arnon to Heshbon, and in a north-easterly direction nearly as far as Rabbath-Ammon, with the towns of Heshbon, Bezer, Medeba, Jahza, and Dibon (Deu 4:43; Jos 13:9, Jos 13:16-17, Jos 13:21; Jos 20:8; Jer 48:21.), which originally belonged to the Moabites, and is therefore called "the field of Moab" in Num 21:20. "The whole of Gilead," i.e., the mountainous region on the southern and northern sides of the Jabbok, which was divided into two halves by this river. The southern half, which reached to Heshbon, belonged to the kingdom of Sihon (Jos 12:2), and was assigned by Moses to the Reubenites and Gadites (Deu 3:12); whilst the northern half, which is called "the rest of Gilead" in Deu 3:13, the modern Jebel Ajlun, extending as far as the land of Bashan (Hauran and Jaulan), belonged to the kingdom of Og (Jos 12:5), and was assigned to the Manassite family of Machir (Deu 3:15, and Jos 13:31; cf. v. Raumer, Pal. pp. 229, 230). "And all Bashan unto Salcah and Edrei." All Bashan included not only the country of Hauran (the plan and mountain), but unquestionably also the district of Jedur and Jaulan, to the west of the sea of Galilee and the upper Jordan, or the ancient Gaulonitis (Jos. Ant. xviii. 4, 6, etc.), as the kingdom of Og extended to the coasts of Geshuri and Maachathi (see at Deu 3:14). Og had not conquered the whole of the land of Hauran, however, but only the greater part of it. His territory extended eastwards to Salcah, i.e., the present Szalchat or Szarchad, about six hours to the east of Bozrah, south of Jebel Hauran, a town with 800 houses, and a castle upon a basaltic rock, but uninhabited (cf. v. Raumer, Pal. p. 255); and northwards to Edrei, i.e., the northern Edrei (see at Num 21:33), a considerable ruin on the northwest of Bozrah, three or four English miles in extent, in the old buildings of which there are 200 families living at present (Turks, Druses, and Christians). By the Arabian geographers (Abulfeda, Ibn Batuta) it is called Sora, by modern travellers Adra or Edra (v. Richter), or Oezraa (Seetzen), or Ezra (Burckhardt), and Edhra (Robinson, App. 155). Consequently nearly the whole of Jebel Hauran, and the northern portion of the plain, viz., the Leja, were outside the kingdom of Og and the land of Bashan, of which the Israelites took possession, although Burckhardt reckons Ezra as part of the Leja.
