Deuteronomy 2:4-9

4And command thou the people, saying, Ye are to pass through the land of your brethren the children of Esau, who dwell in Seir; and they shall be afraid of you: therefore take ye good heed to yourselves: 5Meddle not with them; for I will not give you of their land, no, not so much as a foot breadth; because I have given mount Seir to Esau for a possession.1 6Ye shall buy food of them for money, that ye may eat; and ye shall also buy water of them for money, that ye may drink. 7For the LORD thy God hath blessed thee in all the works of thy hand: he knoweth thy walking through this great wilderness: these forty years the LORD thy God hath been with thee; thou hast lacked nothing.

8And when we passed by from our brethren the children of Esau, who dwelt in Seir, through the way of the plain from Elath, and from Eziongaber, we turned and passed by the way of the wilderness of Moab. 9And the LORD said to me, Distress not the Moabites, neither contend with them in battle: for I will not give thee of their land for a possession; because I have given Ar to the children of Lot for a possession.2
