Deuteronomy 2:4-9

and command the people, “You are about to pass through the territory of your brothers, the people of Esau, who live in Seir; and they will be afraid of you. So be very careful. Do not contend with them, for I will not give you any of their land, no, not so much as for the sole of the foot to tread on, because I have given Mount Seir to Esau as a possession. You shall purchase food from them with money, that you may eat, and you shall also buy water from them with money, that you may drink. For the LORD your God has blessed you in all the work of your hands. He knows your going through this great wilderness. These forty years the LORD your God has been with you. You have lacked nothing.”’ So we went on, away from our brothers, the people of Esau, who live in Seir, away from the Arabah road from Elath and Ezion-geber. “And we turned and went in the direction of the wilderness of Moab. And the LORD said to me, ‘Do not harass Moab or contend with them in battle, for I will not give you any of their land for a possession, because I have given Ar to the people of Lot for a possession.’
