'Area' in the Bible
The Lord our God spoke to us at Horeb and said, "You have stayed in the area of this mountain long enough.
Turn [now] and {move on}, and go [into] the hill of the Amorites and to all [of] the neighboring regions in the Jordan {Valley} in the hill country and in the Negev and in the coastal area along the sea, [into] the land of the Canaanites and [into] the Lebanon, as far as the great river Euphrates.
The Amorite inhabitants of that area confronted you and chased you like a swarm of bees, striking you down from Seir as far as Hormah.
This is exactly what he did for the descendants of Esau who lived in Seir when he destroyed the Horites before them so that they could dispossess them and settle in their area to this very day.
“At that time we took possession of this land. I gave to the Reubenites and Gadites the area extending from Aroer by the Arnon Valley, and half the hill country of Gilead along with its cities.
And the remainder of Gilead and all of Bashan, the kingdom of Og, I gave to the half-tribe of Manasseh, the whole region of Argo. All of that [area of] Bashan was called [the] land of the Rephaim.
and I gave to the Reubenites and Gadites the area extending from Gilead to the Arnon Valley (the middle of the valley was the border) and up to the Jabbok River, the border of the Ammonites.
