A brief family record traces the lineage and descendants of King Saul. This genealogy acts as a vital bridge to the story of David's reign. Because the broader historical account focuses primarily on the kings of Judah, detailing Saul's family line sets the stage for the account of his and his sons' deaths. Moving past their downfall, the narrative then follows the survivors of Saul's family, highlighting how God blessed the remaining lineage with many children [רלב״ג, ביאור שטיינזלץ].
Among the listed sons of Saul is Eshbaal. In other historical records, specifically in the book of Samuel, he is referred to as Ishvi, and more commonly as Ish-bosheth, the son who ruled over Israel following Saul's death [מצודת דוד]. The variation in his name reflects a shift in language and perception. Originally, the word "baal" simply meant a master or lord. Over time, however, the name was altered to "bosheth," meaning shame, serving as a derogatory label [רש״י].
