Genesis 36:7-9

Young's Literal Translation

⁷ for their substance was more abundant than to dwell together, and the land of their sojournings was not able to bear them because of their cattle;

⁸ and Esau dwelleth in mount Seir: Esau is Edom.

⁹ And these [are] births of Esau, father of Edom, in mount Seir.
