Genesis 36:1-8

Now these are the records of the descendants of Esau, (that is, Edom). Esau took his [three] wives from the daughters of Canaan: Adah the daughter of Elon the Hittite, and Oholibamah the daughter of Anah, the son of Zibeon the Hivite, and Basemath, Ishmael’s daughter, sister of Nebaioth. Adah bore Eliphaz to Esau, and Basemath bore Reuel, and Oholibamah bore Jeush, Jalam, and Korah. These are the sons of Esau born to him in Canaan. Now Esau took his wives and his sons and his daughters and all the members of his household, and his livestock and all his cattle and all his possessions which he had acquired in the land of Canaan, and he went to a land away from his brother Jacob. For their [great flocks and herds and] possessions made it impossible for them to live together [in the same region]; the land in which they lived temporarily could not support them because of their livestock. So Esau lived in the hill country of Seir; Esau is Edom.
