The aftermath of the battle leaves Jerusalem stripped of its wealth and dignity. Following a decisive victory, the king of Israel plunders the city, claiming vast spoils before making his way back to Samaria. This loot includes the sacred treasures kept within the Temple, the accumulated wealth of the royal palace, and human captives taken as prizes of war.
Among the captives are individuals held specifically as human collateral. The primary approach among commentators is that these prisoners are the sons of local ministers and high-ranking dignitaries. They were originally kept in the royal palace as hostages to guarantee that their powerful fathers would not rebel against the crown. Alternatively, some suggest [ביאור שטיינזלץ] that these hostages are actually from foreign nations or smaller neighboring tribes, previously held captive in the Judean king's court before being taken by the invading army.
The invading king's return to Samaria marks the end of this devastating event, but the historical aftermath reveals a striking irony [רלב״ג, רד״ק]. The king of Israel had displayed immense pride, boasting to the king of Judah about his impending defeat. Yet, despite his overwhelming triumph in this campaign, the king of Israel dies shortly after these events. In a surprising turn of fate, the defeated king of Judah goes on to live for another fifteen years following his conqueror's death, even though the exact year the war itself took place remains unknown.
