Deuteronomy 2:3

Then we turned, and took our journey into the wilderness by the way of the Red sea, as the LORD spake unto me: and we compassed mount Seir many days.

And the LORD spake unto me, saying,

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:

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.
