ישעיהו, פרק ס׳, פסוק כ״א

In the end of days, the people of Israel will experience an absolute purification, securing their eternal connection to the Land of Israel. This transformation is compared to the growth of a magnificent tree, planted and directly tended by God. A profound question arises regarding how an entire nation can achieve such a flawless spiritual state. The primary approach among commentators is that this will result from a harsh refining process through the suffering of exile and the struggles preceding the Messianic era. During this time, the wicked will fade away, leaving behind a remnant that is entirely holy and pure [מצודת דוד, רד״ק, צאינה וראינה]. Offering a different perspective, others explain this transformation through the concept of reincarnation. In this view, human souls are planted in the world time after time until they are fully corrected and perfected, ultimately resulting in a generation where every individual is righteous [צוארי שלל].

As a direct result of this righteousness, the nation is promised an eternal inheritance. First and foremost, this carries profound geographical and historical weight: the people will possess the Land of Israel permanently, never to face exile again [מצודת דוד, רד״ק, ביאור שטיינזלץ, מלבי״ם]. Beyond the national level, this promise extends to the personal and family life of the people. No individual will pass away without children, ensuring that their family line is never cut off from their ancestral property, and they will multiply and thrive [שד״ל].

The growth and development of the nation are vividly compared to a small, tender branch sprouting from a root [מצודת ציון, אבן עזרא, ביאור שטיינזלץ]. Though the nation may currently appear weak and fragile like a new shoot, it is a direct planting by God. He will nurture it until it stands as a large, powerful, and independent tree [מלבי״ם, ביאור שטיינזלץ]. This stands in sharp contrast to their history. In the past, the nation was compared to a foreign vine that yielded ruined fruit, but in the future, their actions will prove they are an authentic planting of God [רד״ק]. The divine pride they inspire is closely tied to the image of spreading branches, promising that this once-tender shoot will eventually expand and flourish [מלבי״ם].

Ultimately, the people will be recognized as the work of God's own hands, a status that expresses deep divine joy. God will take pride in the nation [רש״י, מצודת דוד], much like an artisan who rejoices when His creation is finally flawless and complete [אבן עזרא]. This supreme standing will elevate the people to extraordinary spiritual heights. As the masterpiece of God's hands, they will radiate a brilliant spiritual light, echoing the pure illumination of the very first human before the first sin [אהבת יהונתן].
