Deuteronomy 2:8-9

8So we went on past our relatives the descendants of Esau, who live in Seir. We turned from the Arabah road, which comes up from Elath and Ezion Geber, and traveled along the desert road of Moab.

9Then the LORD said to me, “Do not harass the Moabites or provoke them to war, for I will not give you any part of their land. I have given Ar to the descendants of Lot as a possession.”
