Genesis 36:6-8

And Esau took his wives, and his sons, and his daughters, and all the souls of his house, and his cattle, and all his beasts, and all his possessions, which he had gathered in the land of Canaan; and went into a land away from his brother Jacob. For their substance was too great for them to dwell together; and the land of their sojournings could not bear them because of their cattle. And Esau dwelt in mount Seir: Esau is Edom.
