The rise and fall of empires might appear to be driven by military might, political strategy, or simple chance, but history is entirely guided by divine providence. God alone orchestrates geopolitical events to bring about the redemption of His people. The success of a conquering leader and the collapse of a mighty empire are never the result of historical necessity, nature, or luck; rather, they are the direct outcome of God's specific decree [מלבי״ם].
By firmly stressing His own involvement, God emphasizes His solitary role in shaping these events, making it clear that He alone decreed what would happen [רד״ק, מצודת דוד]. This strong declaration also reflects His eternal nature, confirming that He always was and always will be [רד״ק], and that His essence never changes [אבן עזרא]. Beyond His eternal nature, this emphasis connects different eras of salvation, reminding the people that the very same God who saved the Israelites from Egypt will ultimately save them from their final exile, gathering them from the four corners of the earth [רש״י].
Every major shift in power is decided by God well in advance [מלבי״ם]. When a specific leader emerges to change the course of history, it is because God has personally summoned him. The primary approach among commentators is that this summons refers to a specific redeemer [ביאור שטיינזלץ], namely King Cyrus. God called him by name [רד״ק], stirred his heart to take action [מצודת דוד], and directed him to go to war [מלבי״ם]. However, another perspective suggests that this divine calling actually refers to Abraham. In this view, God raised Abraham up and exalted him, choosing him to be one of His greatest and most devoted followers [רש״י].
Focusing on the military campaign of Cyrus, God's guidance is practical and absolute. He is the one who actively brought the foreign king to the city of Babylon [מצודת דוד, רד״ק, מלבי״ם]. God's promise of success ensures that the conqueror will achieve a total victory and successfully destroy the empire [מלבי״ם].
