Deuteronomy 3:3-16

³ So the Lord our God gave into our hand Og also, the king of Bashan, and all his people; and we smote him until no survivor was left to him. ⁴ And we took all his cities at that time--there was not a city which we did not take from them--sixty cities, the whole region of Argob, the kingdom of Og in Bashan. ⁵ All these were cities fortified with high walls, gates, and bars, besides very many unwalled villages. ⁶ And we utterly destroyed them, as we did to Sihon the king of Heshbon, destroying every city, men, women, and children. ⁷ But all the cattle and the spoil of the cities we took as our booty. ⁸ So we took the land at that time out of the hand of the two kings of the Amorites who were beyond the Jordan, from the valley of the Arnon to Mount Hermon ⁹ (the Sido'nians call Hermon Si'rion, while the Amorites call it Senir), ¹⁰ all the cities of the tableland and all Gilead and all Bashan, as far as Sal'ecah and Ed're-i, cities of the kingdom of Og in Bashan. ¹¹ (For only Og the king of Bashan was left of the remnant of the Reph'aim; behold, his bedstead was a bedstead of iron; is it not in Rabbah of the Ammonites? Nine cubits was its length, and four cubits its breadth, according to the common cubit.)

Reuben, Gad, and Half of Manasseh Settle East of the Jordan

¹² "When we took possession of this land at that time, I gave to the Reubenites and the Gadites the territory beginning at Aro'er, which is on the edge of the valley of the Arnon, and half the hill country of Gilead with its cities; ¹³ the rest of Gilead, and all Bashan, the kingdom of Og, that is, all the region of Argob, I gave to the half-tribe of Manas'seh. (The whole of that Bashan is called the land of Reph'aim. ¹⁴ Ja'ir the Manas'site took all the region of Argob, that is, Bashan, as far as the border of the Gesh'urites and the Ma-ac'athites, and called the villages after his own name, Hav'voth-ja'ir, as it is to this day.) ¹⁵ To Machir I gave Gilead, ¹⁶ and to the Reubenites and the Gadites I gave the territory from Gilead as far as the valley of the Arnon, with the middle of the valley as a boundary, as far over as the river Jabbok, the boundary of the Ammonites;
