Deuteronomy 2:4-8

and command the people, saying, “You are going to pass through the territory of your brothers the sons of Esau, who live in Seir; and they will be afraid of you. So be very careful;

do not provoke them, for I will not give you any of their land, not even as much as a footprint, because I have given Mount Seir to Esau as a possession.

You are to buy food from them with money so that you may eat, and you shall also purchase water from them with money so that you may drink.

For the Lord your God has blessed you in all that you have done; He has known your wandering through this great wilderness. These forty years the Lord your God has been with you; you have not lacked anything.” ’

“So we passed beyond our brothers the sons of Esau, who live in Seir, away from the Arabah road, away from Elath and Ezion-geber. And we turned and passed through by the way of the wilderness of Moab.
