Deuteronomy 3:8

4 At that time we captured all sixty of his cities. There was not a single city we failed to take—the entire region of Argob, the kingdom of Og in Bashan.

5 All these cities were fortified with high walls and gates and bars, and there were many more unwalled villages.

6 We devoted them to destruction, as we had done to Sihon king of Heshbon, utterly destroying the men, women, and children of every city.

7 But all the livestock and plunder of the cities we carried off for ourselves.

8 At that time we took from the two kings of the Amorites the land across the Jordan, from the Arnon Valley as far as Mount Hermon—

9 which the Sidonians call Sirion but the Amorites call Senir—

10 all the cities of the plateau, all of Gilead, and all of Bashan as far as the cities of Salecah and Edrei in the kingdom of Og.

11 (For only Og king of Bashan had remained of the remnant of the Rephaim. His bed of iron, nine cubits long and four cubits wide, is still in Rabbah of the Ammonites.)

12 So at that time we took possession of this land. To the Reubenites and Gadites I gave the land beyond Aroer along the Arnon Valley, and half the hill country of Gilead, along with its cities.
