we journeyed back into the wilderness, in the direction of the Red Sea, as the Lord had told me and skirted Mount Seir for many days.
References for Deuteronomy 2:1
Then the Lord said to me:
"You have been skirting this hill country long enough. Head north,
and charge the people as follows: You are about to pass through the territory of your kindred, the descendants of Esau, who live in Seir. They will be afraid of you, so, be very careful
not to engage in battle with them, for I will not give you even so much as a foot's length of their land, since I have given Mount Seir to Esau as a possession.
You shall purchase food from them for money, so that you may eat; and you shall also buy water from them for money, so that you may drink.
