Genesis 36:7-9

New Catholic Bible

⁷ Their possessions, in fact, were too extensive for them to live together, and the land in which they were living could not sustain the grazing of all their animals. ⁸ Esau thus dwelt in the mountains of Seir. Now Esau is Edom.

⁹ These are the descendants of Esau, the father of the Edomites, in the mountains of Seir.
