Origins and family
The Genesis narrative identifies Rebecca as the daughter of Bethuel the Aramean and the sister of Laban, and a granddaughter of Nahor, the brother of Abraham. Her home was in Paddan-Aram (Aram-Naharaim), the region of Haran in Mesopotamia. The in-repo record gives her region of origin as Mesopotamia, consistent with the scriptural account.
Through her marriage to Isaac she became part of the patriarchal household of Abraham, and her twin sons Esau and Jacob continued the line; Jacob, later named Israel, became the patriarch from whom the tribes of Israel descend.
