Deuteronomy 2:2-7

And the LORD spoke to me, saying, ‘You have circled this mountain long enough; turn northward, and command the people, saying, “You are passing through the territory of your brothers the sons of Esau (the Edomites), who live in Seir; and they will be afraid of you. So be very careful; do not provoke them, for I will not give you any of their land, not even as little as a footstep, because I have given Mount Seir to Esau as a possession. You shall buy food from them with money so that you may [have something to] eat, and you shall also buy water from them with money so that you may [have something to] drink. For the LORD your God has blessed you in all that you have done; He has known about your wanderings through this great wilderness. These forty years the LORD your God has been with you; you have lacked nothing.” ’
