Deuteronomy 2:6

3 Ye have compassed this mountain long enough: turn you northward.

4 And command thou the people, saying, Ye are to pass through the coast of your brethren the children of Esau, which dwell in Seir; and they shall be afraid of you: take ye good heed unto yourselves therefore:

5 Meddle 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 unto Esau for a possession.

6 Ye shall buy meat of them for money, that ye may eat; and ye shall also buy water of them for money, that ye may drink.

7 For 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.

8 And when we passed by from our brethren the children of Esau, which 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.

9 And the LORD said unto 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 unto the children of Lot for a possession.
