Exiled and displaced, the people receive a revelation of God's long-term design for their survival. He assures them that their prolonged stay in Babylon is not a decree of destruction, but rather a carefully designed process meant to lead them toward a safe and prosperous future. This message directly counters the claims of false prophets who promised an immediate return, clarifying God's true intentions [אברבנאל]. The primary approach among commentators is that the seventy-year delay is not a punishment, but a deeply positive and necessary process.
God emphasizes that His plans are intended purely for their well-being. The experience of exile itself is for the nation's benefit, serving to humble their hearts and correct their behavior before they return to their homeland [מצודת דוד]. While human plans for peace can often turn bad due to shifting circumstances, God promises that His Divine plan will remain entirely positive, ultimately resulting in a stable and secure existence in the land [מלבי״ם].
Taking a broader historical view, this promised period of peace indicates that the return to Israel after seventy years was never meant to be the final redemption. Instead, it was an essential preparatory stage. God chose to return the people to the land to provide them with the proper spiritual environment to repent and pray. These spiritual actions were meant to eventually trigger a complete ingathering of the exiles and a total, final redemption [אברבנאל].
The culmination of this Divine promise guarantees that a remnant of the nation will survive to experience ultimate happiness and true purpose [מצודת ציון, ביאור שטיינזלץ]. In contrast to the wicked, whose success is fleeting and who possess no lasting future, the righteous are assured of success at the end of their difficult journey [מלבי״ם]. God has prepared a destiny of growth and prosperity that perfectly matches the people's deepest desires [רד״ק, ביאור שטיינזלץ]. Throughout their long years of waiting in exile, hope will sustain them until they finally reach this awaited destiny [מלבי״ם]. Ultimately, this final goal of a secure future was the complete and universal redemption, a reality that would have fully materialized had the people properly utilized the spiritual opportunity granted to them during the era of the Second Temple [אברבנאל].
