ישעיהו, פרק ס״ג, פסוק ד׳

God's decision to act swiftly and no longer delay His anger against the nations is driven by the arrival of a dual moment: the time to punish the enemies and the time to save Israel [מלבי״ם]. The primary approach among commentators is that this retribution is the culmination of a long-term plan. The thought of this reckoning was kept hidden in God's heart for a long time, waiting for the precise moment to be brought into reality.

This judgment does not happen in isolation. It is deeply intertwined with a pre-decreed era of salvation for the people of Israel. The time of redemption is exactly when the day of vengeance takes effect [רד״ק, ביאור שטיינזלץ]. The use of a year to describe this salvation is highly intentional. It points directly to the concept of the Jubilee, a time traditionally defined by freedom and the release of captives, marking a period of divine favor [שד״ל]. Ultimately, those who are saved are the ones who love God. Speaking directly, God testifies that these individuals are intimately His own redeemed people [אבן עזרא].
