Deuteronomy 2:4–6

4 and command the people, “You are about to pass through the territory of gyour brothers, the people of Esau, hwho live in Seir; and ithey will be afraid of you. So be very careful. 5 Do not 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 hI have given Mount Seir to Esau as a possession. 6 jYou shall purchase food from them with money, that you may eat, and you shall also buy water from them with money, that you may drink.
