דברי הימים ב, פרק י״ח, פסוק ל׳

The battlefield strategy of the Aramean army shifts dramatically from a standard military conflict to a highly focused assassination mission. The command given to the chariot commanders is absolute and clear: they are to ignore the general chaos of war and hunt down a single man.

The commanders are explicitly instructed not to engage in combat with ordinary soldiers or high-ranking officers. Instead of fighting the enemy army at large, their sole objective is the elimination of Ahab, the King of Israel [ביאור שטיינזלץ].

This intense and singular focus on the Israelite king stems from a gathering that occurred before the battle. The King of Aram had spies present when the prophet Micaiah delivered his grim prediction regarding Ahab's impending downfall before Jehoshaphat at the threshing floor by the gates of Samaria. After these spies relayed the prophecy back to the King of Aram, he formulated his battle plan accordingly, ordering his forces to direct all their combat efforts exclusively toward the King of Israel [חומת אנך].
