Genesis 36:5-9

5And Aholibamah bore Jeush, Jaalam, and Korah. These were the sons of Esau who were born to him in the land of Canaan.

6Then Esau took his wives, his sons, his daughters, and all the persons of his household, his cattle and all his animals, and all his goods which he had gained in the land of Canaan, and went to a country away from the presence of his brother Jacob.

7For their possessions were too great for them to dwell together, and the land where they were strangers could not support them because of their livestock.

8So Esau dwelt in Mount Seir. Esau is Edom.

9And this is the genealogy of Esau the father of the Edomites in Mount Seir.
