and Basemath, the daughter of Ishmael and sister of Nebaioth. 2
References for Genesis 36:3
Adah bore Eliphaz; Basemath bore Reuel;
and Oholibamah bore Jeush, Jalam, and Korah. All these sons were born to Esau in the land of Canaan.
Then Esau took his wives, his sons, his daughters, and all the people of his house, along with all his livestock and all the possessions he had gotten in the land of Canaan, and went away from his brother Jacob to another land.
He left because the land where he and Jacob were living was not able to support them; they had too much livestock and could no longer stay together.
So Esau lived in the hill country of Edom.
These are the descendants of Esau, the ancestor of the Edomites.
Esau's wife Adah bore him one son, Eliphaz, and Eliphaz had five sons: Teman, Omar, Zepho, Gatam, and Kenaz. And by another wife, Timna, he had one more son, Amalek. Esau's wife Basemath bore him one son, Reuel, and Reuel had four sons: Nahath, Zerah, Shammah, and Mizzah.
Esau's wife Oholibamah, the daughter of Anah son of Zibeon, bore him three sons: Jeush, Jalam, and Korah.
