All the cities of the plain,.... There was a plain by Medeba, and Heshbon and her cities were in a plain, with some others given to the tribe of Reuben, Joshua 13:16
and all Gilead; Mount Gilead, and the cities belonging to it, a very fruitful country, half of which fell to the share of the Reubenites, and the rest to the half tribe of Manasseh:
and all Bashan; of which Og was king, called Batanea, a very fertile country, as before observed:
unto Salcah and Edrei, cities of the kingdom of Og in Bashan; which seem to be frontier cities of the latter: see Deuteronomy 1:4. The former, Adrichomius p says, was situated by the city Geshur and Mount Hermon, and was the boundary of the country of Bashan to the north; and according to Benjamin of Tudela q, it was half a day's journey from Gilead: as Edrei seems to be its boundary to the south.
