Deuteronomy 3:8-12

8“So we took the land of the two Amorite kings east of the Jordan River—all the way from the Arnon Gorge to Mount Hermon.

9(Mount Hermon is called Sirion by the Sidonians, and the Amorites call it Senir.)

10We had now conquered all the cities on the plateau and all Gilead and Bashan, as far as the towns of Salecah and Edrei, which were part of Og’s kingdom in Bashan.

11(King Og of Bashan was the last survivor of the giant Rephaites. His bed was made of iron and was more than thirteen feet long and six feet wide. It can still be seen in the Ammonite city of Rabbah.)

12“When we took possession of this land, I gave to the tribes of Reuben and Gad the territory beyond Aroer along the Arnon Gorge, plus half of the hill country of Gilead with its towns.
