Deuteronomy 2:2-6

2“And the Lord spoke to me, saying:

3‘You have skirted this mountain long enough; turn northward.

4And command the people, saying, “You are about to pass through the territory of your brethren, the descendants of Esau, who live in Seir; and they will be afraid of you. Therefore watch yourselves carefully.

5Do not meddle with them, for I will not give you any of their land, no, not so much as one footstep, because I have given Mount Seir to Esau as a possession.

6You shall buy food from them with money, that you may eat; and you shall also buy water from them with money, that you may drink.
