'Region' in the Bible

Only the land of {the Ammonites} you did not approach, [all along] the whole upper region of the Jabbok {River} and the towns of the hill country, [according to all] that Yahweh our God had instructed.

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.

Jair the descendant of Manasseh acquired the whole region of Argob, up to the boundary of the Geshurites and the Maacathites, and he called it, [that is] Bashan, after his [own] name, Havvoth Jair, {as it still is today}.
