ירמיהו, פרק ל״ג, פסוק ז׳

The promise of redemption centers on a complete national restoration, focusing both on bringing a scattered people back from exile and rebuilding them to their original standing. The end of captivity involves physically returning the exiles to their homeland [מצודת דוד, מצודת ציון, מלבי״ם]. This gathering will encompass the entire nation, specifically including the return of the exiled Ten Tribes [ביאור שטיינזלץ].

Beyond the physical return to the land, the people are promised that they will be rebuilt. Commentators understand this concept of building on two complementary levels. On a fundamental level, being built up represents a return to an abundance of goodness and success, restoring the prosperity the nation experienced in the past [מצודת דוד]. On a practical and national level, it involves actual construction. This means the physical reestablishment of the kingdom, the city of Jerusalem, and the Temple [מלבי״ם].
