Deuteronomy 1:2-3, 8

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

See, I have given you this land. Go in and take possession of the land the LORD swore he would give to your fathers—to Abraham, Isaac and Jacob—and to their descendants after them.”
