בראשית, פרק ל״ו, פסוק י״ג

The historical record continues to map out the expanding generations, focusing on the descendants of Reuel. His four sons are identified as Nahath, Zerah, Shammah, and Mizzah.

This specific branch of the family tree is carefully traced back to their grandmother, Basemath, one of Esau's wives. By linking these four men directly to her, the account establishes her distinct legacy and foundational place within the broader family lineage.
