Deuteronomy 1:2-4

2 (It takes eleven days to go from Horeb to Kadesh Barnea by the Mount Seir road.)

3 In the fortieth year, on the first day of the eleventh month, Moses proclaimed to the Israelites all that the LORD had commanded him concerning them.

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