Deuteronomy 4:44-48

Now this is the Law which Moses set before the sons of Israel;

these are the testimonies and the statutes, and the ordinances which Moses spoke to the sons of Israel, when they came out of Egypt,

across the Jordan, in the valley opposite Beth-peor, in the land of Sihon king of the Amorites who lived in Heshbon, whom Moses and the sons of Israel defeated when they came out of Egypt.

And they took possession of his land and the land of Og king of Bashan, the two kings of the Amorites, who were across the Jordan to the east,

from Aroer, which is on the edge of the Valley of Arnon, even as far as Mount Sion (that is, Hermon),
