Deuteronomy 3:8-12

“So at that time we took the land from the hand of the two kings of the Amorites who were beyond the Jordan, from the Valley of Arnon to Mount Hermon

(Sidonians call Hermon Sirion, and the Amorites call it Senir):

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

(For only Og king of Bashan was left of the remnant of the Rephaim. Behold, his bed was a bed of iron; it is in Rabbah of the sons of Ammon. Its length was nine cubits, and its width four cubits by the usual cubit.)

“So we took possession of this land at that time. From Aroer, which is by the Valley of Arnon, and half the hill country of Gilead and its cities I gave to the Reubenites and to the Gadites.
