'Plateau' in the Bible

From Aroer on the rim of the Arnon Valley, along with the city in the middle of the valley, all the Medeba plateau as far as Dibon,

this as their territory:From Aroer on the rim of the Arnon Valley, along with the city in the middle of the valley, to the whole plateau as far as Medeba,

with Heshbon and all its cities on the plateau—Dibon, Bamoth-baal, Beth-baal-meon,

all the cities of the plateau, and all the kingdom of Sihon king of the Amorites, who reigned in Heshbon. Moses had killed him and the chiefs of Midian—Evi, Rekem, Zur, Hur, and Reba—the princes of Sihon who lived in the land.

Across the Jordan east of Jericho, they selected Bezer on the wilderness plateau from Reuben’s tribe, Ramoth in Gilead from Gad’s tribe, and Golan in Bashan from Manasseh’s tribe.
