Genesis 36:6-8

Esau took his wives, his sons, his daughters, and his entire household, and the cattle, livestock, and possessions he had acquired in the land of Canaan, and migrated to the land of Seir some distance from his brother Jacob. Since the land where Jacob was living could not support their combined possessions and livestock, Esau (also known as Edom), settled in the hill country of Seir.
