Genesis 36:5

Esau took his wives from the daughters of Canaan: Adah the daughter of Elon, the Hittite; and Oholibamah the daughter of Anah, the daughter of Zibeon, the Hivite;

and Basemath, Ishmael’s daughter, sister of Nebaioth.

Adah bore to Esau Eliphaz. Basemath bore Reuel.

Esau took his wives, his sons, his daughters, and all the members of his household, with his livestock, all his animals, and all his possessions, which he had gathered in the land of Canaan, and went into a land away from his brother Jacob.

For their substance was too great for them to dwell together, and the land of their travels couldn’t bear them because of their livestock.

Esau lived in the hill country of Seir. Esau is Edom.
