What does Deuteronomy 1:5 mean?

It is eleven days’ journey from Horeb by the way of Mount Seir to Kadesh Barnea.

In the fortieth year, in the eleventh month, on the first day of the month, Moses spoke to the children of Israel, according to all that Yahweh had given him in commandment to them;

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

“Yahweh our God spoke to us in Horeb, saying, ‘You have lived long enough at this mountain.

Turn, and take your journey, and go to the hill country of the Amorites, and to all the places near there, in the Arabah, in the hill country, in the lowland, in the South, by the seashore, in the land of the Canaanites, and in Lebanon, as far as the great river, the river Euphrates.

Behold, I have set the land before you. Go in and possess the land which Yahweh swore to your fathers, to Abraham, to Isaac, and to Jacob, to give to them and to their offspring after them.’”
