Deuteronomy 1:2-4

2It is [only] eleven days’ journey from Horeb (Mount Sinai) by way of Mount Seir to Kadesh-barnea [on Canaan’s border; yet Israel wandered in the wilderness for forty years before crossing the border and entering Canaan, the promised land].

3In the fortieth year, on the first day of the eleventh month, Moses spoke to the children of Israel in accordance with all that the Lord had commanded him to say to them,

4after he had defeated Sihon the king of the Amorites, who lived in Heshbon, and Og the king of Bashan, who lived at Ashtaroth in Edrei.
