Deuteronomy 2:4-5

2:4 Instruct these people as follows: ‘You are about to cross the border of your relatives the descendants of Esau, who inhabit Seir. They will be afraid of you, so watch yourselves carefully. 2:5 Do not be hostile toward them, because I am not giving you any of their land, not even a footprint, for I have given Mount Seir as an inheritance for Esau.
