Deuteronomy 2:4-7

and command the people, saying, “You will pass through the territory of your brothers the sons of Esau 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, 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 eat, and you shall also purchase water from them with money so that you may drink. For the LORD your God has blessed you in all that you have done; He has known your wanderings through this great wilderness. These forty years the LORD your God has been with you; you have not lacked a thing.” ’
