Deuteronomy 3:12-13

LEB(i) 12 And so we took possession of this land at that time, from Aroer, which is on the edge of the wadi* of Arnon, and also half of the hill country of Gilead and its towns I gave to the Reubenites* and to the Gadites.* 13 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.
