"And the heart of Pharaoh was reversed" (Exodus 14:5). The Mekhilta reads this reversal not as a change of mind about letting Israel go, but as the collapse of an empire.
When Israel left Egypt, the kingdom of Pharaoh effectively came to an end. The reversal of his heart was the reversal of his power. Everything that had made Egypt great — its labor force, its wealth, its military dominance — walked out the door with the Hebrew slaves.
The Mekhilta supports this reading with a devastating verse from the prophet Ezekiel: "Whom have you surpassed in beauty? Descend and be laid to rest with the uncircumcised!" (Ezekiel 32:19). This prophecy against Egypt describes a once-glorious nation being told to take its place among the dead. The splendor is over. The beauty has faded. Egypt must descend into the grave alongside the nations it once looked down upon.
The Mekhilta connects this prophetic funeral dirge directly to the moment of the Exodus. The reversal of Pharaoh's heart was not merely psychological. It was historical. The instant Israel crossed the border, Egypt began its long decline from the greatest civilization on earth to a nation laid low among the uncircumcised dead. The Exodus did not just free Israel. It broke Egypt.
