Genesis 36:1-3

This is the account of the descendants of Esau (also known as Edom). Esau married two young women from Canaan: Adah, the daughter of Elon the Hittite; and Oholibamah, the daughter of Anah and granddaughter of Zibeon the Hivite. He also married his cousin Basemath, who was the daughter of Ishmael and the sister of Nebaioth.
