Deuteronomy 3:8-12

8At 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— 9which the Sidonians call Sirion but the Amorites call Senir— 10all 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,1 is still in Rabbah of the Ammonites.)

12So 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.
