Genesis 36:6-8

6And Esau took his wives, and his sons, and his daughters, and all the persons of his house, and his cattle, and all his beasts, and all his substance, which he had got in the land of Canaan; and went into the country from the face of his brother Jacob.1

7For their riches were more than that they might dwell together; and the land wherein they were strangers could not bear them because of their cattle.

8Thus dwelt Esau in mount Seir: Esau is Edom.
