שמואל ב, פרק ב׳, פסוק י״ג

Two rival military forces find themselves face to face in a moment of tense quiet, waiting to see how their sudden encounter will unfold. Joab son of Zeruiah, the commander of David's army, had led his men out to scout and patrol the land [אברבנאל]. As they moved through the territory, they stumbled into a completely random meeting with Abner's camp [מלבי״ם]. Commentators agree that this was a sudden, unexpected crossing of paths between the two groups.

The armies met near the pool of Gibeon, a structure built of stone and plaster designed to collect and store water [מצודת ציון]. Following their surprise encounter, the camps decided to settle down on opposite sides of the pool. This physical arrangement reflects a highly complex atmosphere. In one sense, they sat near each other in relative peace, sharing a mood of brotherly calm [מלבי״ם]. At the same time, this divided seating arrangement was driven by calculated caution. By keeping the water between them, the two armies maintained a safe distance to avoid any immediate physical contact or direct conflict [ביאור שטיינזלץ].
