Deuteronomy 2:8-9

8So we passed by our relatives, the descendants of Esau, who lived in Seir. We turned off the road that goes through the plains to Elath and Ezion Geber and took the road that goes through the desert of Moab.

9The Lord said to me, “Don’t bother the people of Moab or start a war with them. I’m not giving you any of Ar as your property. I have given it to the descendants of Lot.”
