Genesis 36:5-8

5And Oholibamah bore Jeush and Jaalam and Korah. These are the sons of Esau that were born to him in the land of Canaan.

6And 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, that he had acquired in the land of Canaan, and went into a country away from his brother Jacob.

7For their property was too great for them to dwell together, and the land where they were sojourners could not bear them, because of their cattle.

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