Genesis 36:7-9

New Century Version

⁷ Esau and Jacob’s belongings were becoming too many for them to live in the same land. The land where they had lived could not support both of them, because they had too many herds. ⁸ So Esau lived in the mountains of Edom. (Esau is also named Edom.)

⁹ This is the family history of Esau. He is the ancestor of the Edomites, who live in the mountains of Edom.
