Deuteronomy 2:31-3:14
And the Lord said to me: See, I begin by placing Sihon and his land at your disposal. Begin the occupation; take possession of his land.
Sihon with all his men took the field against us at Jahaz, and the Lord our God delivered him to us and we defeated him and his sons and all his men. At that time we captured all his towns, and we doomed every town--men, women, and children--leaving no survivor. We retained as booty only the cattle and the spoil of the cities that we captured. From Aroer on the edge of the Arnon valley, including the town in the valley itself, to Gilead, not a city was too mighty for us; the Lord our God delivered everything to us. But you did not encroach upon the land of the Ammonites, all along the wadi Jabbok and the towns of the hill country, just as the Lord our God had commanded.
We made our way up the road toward Bashan, and King Og of Bashan with all his men took the field against us at Edrei. But the Lord said to me: Do not fear him, for I am delivering him and all his men and his country into your power, and you will do to him as you did to Sihon king of the Amorites, who lived in Heshbon.
So the Lord our God also delivered into our power King Og of Bashan, with all his men, and we dealt them such a blow that no survivor was left. 4 At that time we captured all his towns; there was not a town that we did not take from them: sixty towns, the whole district of Argob, the kingdom of Og in Bashan all those towns were fortified with high walls, gates, and bars--apart from a great number of unwalled towns. We doomed them as we had done in the case of King Sihon of Heshbon; we doomed every town--men, women, and children--and retained as booty all the cattle and the spoil of the towns.
Thus we seized, at that time, from the two Amorite kings, the country beyond the Jordan, from the wadi Arnon to Mount Hermon--Sidonians called Hermon Sirion, and the Amorites call it Senir--all the towns of the Tableland and the whole of Gilead and Bashan as far as Salcah and Edrei, the towns of Og's kingdom in Bashan. Only King Og of Bashan was left of the remaining Rephaim. His bedstead, an iron bedstead, is now in Rabbah of the Ammonites; it is nine cubits long and four cubits wide, by the standard cubit!
And this is the land which we apportioned at that time: The part from Aroer along the wadi Arnon, with part of the hill country of Gilead and its towns, I assigned to the Reubenites and the Gadites. The rest of Gilead, and all of Bashan under Og's rule--the whole Argob district, all that part of Bashan which is called Rephaim country--I assigned to the half-tribe of Manasseh. Jair son of Manasseh received the whole Argob district (that is, Bashan) as far as the boundary of the Geshurites and the Maacathites, and named it after himself. Havvoth-jair--as is still the case.
