During a time of severe historical crisis, an urgent call goes out for unity and a return to God. Fast-moving messengers travel across the land, equipped with written letters [מצודת ציון], carrying a message of warning and hope to mend the broken ties between the divided kingdoms. These letters are primarily directed at the Israelites living outside the borders of Judah [ביאור שטיינזלץ]. However, their mission is not limited to delivering written documents; they are commanded to speak the message aloud, ensuring the king's appeal is heard directly by the people [מלבי״ם].
The core of this royal appeal rests on a clear cause and effect. The king urges the people to repent and turn back to God, promising that if they do, God will return to them, show mercy, and come to their defense [מצודת דוד, ביאור שטיינזלץ]. This spiritual shift is presented as an absolute necessity to prevent God from bringing further punishment and destruction upon those who remain [מלבי״ם].
This appeal is specifically aimed at the survivors of the Kingdom of Israel, a fractured group that managed to find rescue and escape the crushing grip of the Assyrian empire [מצודת ציון, ביאור שטיינזלץ]. The tragic reality of these survivors is understood through a few complementary historical events. A significant portion of the nation, particularly those living across the Jordan River, had already been forced into exile by Assyria, leaving only a fragile remnant behind [מצודת דוד]. Furthermore, even those who remained in their homes lived under the heavy shadow of captivity. Dating back to the days of King Ahaz, the Assyrians had asserted dominance, forcing the Israelites into subjugation. For six years, the people paid heavy tribute and lived under absolute control, knowing that the slightest rebellion would result in immediate exile. Therefore, the surviving remnant consists of those who endured this intense pressure and managed to avoid total domination by the Assyrian forces [רש״י].
