Genesis 36:5-8

5Oholibamah gave birth to sons named Jeush, Jalam, and Korah. All these sons were born to Esau in the land of Canaan.

6Esau took his wives, his children, and his entire household, along with his livestock and cattle—all the wealth he had acquired in the land of Canaan—and moved away from his brother, Jacob.

7There was not enough land to support them both because of all the livestock and possessions they had acquired.

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