Genesis 36:7-9

Revised Standard Version

⁷ For their possessions were too great for them to dwell together; the land of their sojournings could not support them because of their cattle. ⁸ So Esau dwelt in the hill country of Se′ir; Esau is Edom.

⁹ These are the descendants of Esau the father of the E′domites in the hill country of Se′ir.
