שמואל ב, פרק ב׳, פסוק י״ב

A tense transition period defines the early days of the divided rule between the emerging kingdoms of David and Ish-bosheth. Although open war has not yet broken out, there is no peace. Both sides are carefully testing boundaries, assessing the situation, and organizing for the inevitable conflict [ביאור שטיינזלץ].

Against this uneasy backdrop, Abner and the men of Ish-bosheth travel from Mahanaim to Gibeon. Their goal is to solidify their power and bring the region of Gibeon under their direct control, as this area geographically belongs to the territory of the tribe of Benjamin [מלבי״ם, רד״ק, ביאור שטיינזלץ]. Ultimately, this strategic advance toward Gibeon serves as the primary spark that ignites the violent clashes between the two rival camps [מלבי״ם].

Opinions differ regarding the exact timing of this military movement. Some suggest that the campaign to Gibeon takes place immediately after Ish-bosheth is crowned in Mahanaim, even before he crosses the Jordan River to return home [רד״ק]. Others argue that this event happens two years into Ish-bosheth's rule, representing a later and entirely separate expedition out of Mahanaim [אברבנאל, מלבי״ם].
