Faced with a national crisis, the leaders of the people—the king and the prophet—unite in prayer. The historical account here does not provide the full text of their plea, choosing instead to capture the core essence of the event. The complete exchange between the two leaders, along with the exact words of the king's prayer, are already recorded at length in the earlier books of Kings and Isaiah [רש״י, ביאור שטיינזלץ].
While those earlier records focus primarily on the king's personal prayer, this narrative introduces a specific new detail. It emphasizes that the prophet Isaiah actively participated alongside the king [מלבי״ם]. Standing together in response to the unfolding events, both leaders directed their shared, urgent cry upward to the heavens [ביאור שטיינזלץ].
