Deuteronomy 4:43-49

43 Bezer in the wilderness on the tableland belonging to the Reubenites, Ramoth in Gilead belonging to the Gadites, and Golan in Bashan belonging to the Manassites.
44 This is the law that Moses set before the Israelites.
45 These are the decrees and the statutes and ordinances that Moses spoke to the Israelites when they had come out of Egypt,
46 beyond the Jordan in the valley opposite Beth-peor, in the land of King Sihon of the Amorites, who reigned at Heshbon, whom Moses and the Israelites defeated when they came out of Egypt.
47 They occupied his land and the land of King Og of Bashan, the two kings of the Amorites on the eastern side of the Jordan:
48 from Aroer, which is on the edge of the Wadi Arnon, as far as Mount Sirion (that is, Hermon),
49 together with all the Arabah on the east side of the Jordan as far as the Sea of the Arabah, under the slopes of Pisgah.
