Deuteronomy 4:44-49
44Now this is the law which Moses set before the sons of Israel; 45these are the testimonies and the statutes and the judgments which Moses spoke to the sons of Israel when they came out from Egypt, 46across the Jordan, in the valley aopposite Beth-peor, in the land of bSihon king of the Amorites who lived at Heshbon, whom Moses and the sons of Israel struck down when they came out from Egypt. 47And they took possession of his land and the land of aOg king of Bashan, the two kings of the Amorites, who were across the Jordan to the east toward the sunrise, 48from aAroer, which is on the edge of the 1valley of Arnon, even as far as bMount Sion (that is, Hermon), 49with all the Arabah across the Jordan to the east, even as far as the sea of the Arabah, 1at the foot of the slopes of Pisgah.
