Genealogies typically trace family records strictly through male descendants. However, the lineage of Jesse breaks from this pattern by including his daughters, Zeruiah and Abigail, alongside his sons. The historical account then specifically names Zeruiah's three sons, Abishai, Joab, and Asahel.
Commentators agree that these women and their children are included in the family record specifically to honor David. Zeruiah's sons grew up to become central heroes, brave men, and powerful military officers recognized from the historical accounts of Samuel. Because they were David's nephews, they closely aligned themselves with him and played a crucial role in supporting his leadership.
Furthermore, identifying these famous warriors by their mother's name serves a deliberate purpose. Tracing the men through Zeruiah directly links them to David's distinguished family line, further emphasizing his honor and the strength of his family ties.
