Deuteronomy 2:4-7

And command thou the people, saying, Ye are to pass through the border of your brethren the children of Esau, that dwell in Seir; and they will be afraid of you. Take ye good heed unto yourselves therefore; contend not with them; for I will not give you of their land, no, not so much as for the sole of the foot to tread on; because I have given mount Seir unto Esau for a possession. Ye shall purchase food of them for money, that ye may eat; and ye shall also buy water of them for money, that ye may drink. For Jehovah thy God hath blessed thee in all the work of thy hand; he hath known thy walking through this great wilderness: these forty years Jehovah thy God hath been with thee; thou hast lacked nothing.
