Genesis 36:6

Esau took his wives and all his substance, &c. Although he had begun to settle among his wives' relations in Seir, before Jacob came from Padan-aram, Genesis 32:3; yet, it is probable, that during the life of Isaac, he had still some effects remaining in Canaan; but after his death, he wholly withdrew to mount Seir, took with him what came to his share of his father's personal estate, and left Canaan to Jacob, not only because Jacob had the promise of it, but because he saw, if they should both continue to thrive, as they had begun, there would not be room for both.
