Deuteronomy 2:3

Then we turned, and took our journey into the wilderness by the way to the Red Sea, as the LORD spoke to me; and we encircled Mount Seir many days.

The LORD spoke to me, saying,

Command the people, saying, ‘You are to pass through the border of your brothers, the children of Esau, who dwell in Seir; and they will be afraid of you. Therefore be careful.

Don’t 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 for a possession.

You shall purchase food from them for money, that you may eat. You shall also buy water from them for money, that you may drink.’”
