Deuteronomy 1:2; Deuteronomy 1:19

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

19 Then, as the LORD our God commanded us, we set out from Horeb and went toward the hill country of the Amorites through all that vast and dreadful wilderness that you have seen, and so we reached Kadesh Barnea.
