Deuteronomy 1:2

There are eleven days' journey - The Israelites were eleven days in going from Horeb to Kadesh-barnea, where they were near the verge of the promised land; after which they were thirty-eight years wandering up and down in the vicinity of this place, not being permitted, because of their rebellions, to enter into the promised rest, though they were the whole of that time within a few miles of the land of Canaan!
