Deuteronomy 2:12; Deuteronomy 2:22

12 The Horites also lived in Seir formerly, but the people of Esau dispossessed them and destroyed them from before them and settled in their place, as Israel did to the land of their possession, which the LORD gave to them.)

22 as he did for the people of Esau, who live in Seir, when he destroyed the Horites before them and they dispossessed them and settled in their place even to this day.
