Genesis 36:5-8

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

6Esau took his wives, his sons, his daughters, all the people in his household, his livestock, his animals, and all his possessions which he had acquired in the land of Canaan and went to a land some distance away from Jacob his brother

7because they had too many possessions to be able to stay together and the land where they had settled was not able to support them because of their livestock.

8So Esau (also known as Edom) lived in the hill country of Seir.
