ישעיהו, פרק כ״ח, פסוק ט״ז

Against a backdrop of false alliances, deceit, and reliance on foreign aid, God promises to establish a secure and enduring center of truth. Directed at cynics and doubters, this message announces the rebuilding of Jerusalem's spiritual fortress and leadership, completely independent of human power. God declares the placement of a firm foundation stone in Zion. Some commentators note that this action is framed as an event that has already occurred, indicating that the divine decree is final and the groundwork for this new kingdom is already in place [רש״י, מלבי״ם, מצודת דוד]. The primary approach among commentators is that this stone serves as a metaphor for a righteous and powerful leader who will deliver the people and inspire them to repent. While many identify this leader specifically as King Hezekiah [רד״ק, מלבי״ם, מצודות], others suggest it refers to the future Messiah [רש״י].

This leader is defined by three distinct qualities that highlight his strength and character. First, he acts as a massive, protective presence. Most commentators understand this as a symbol of a fortress, offering shelter and defense for Zion against any enemy [רש״י, רד״ק, אבן עזרא, שד״ל, מצודות]. Alternatively, it represents a testing stone used to evaluate precious metals, symbolizing a leader who has been tested and proven to be purely righteous and free from corrupt desires, establishing a true standard of justice [מלבי״ם, ביאור שטיינזלץ]. Second, he is likened to a precious cornerstone. Just as a cornerstone is placed at the angle of a building to provide vital stability and is visible from all directions [רד״ק, מצודות, שד״ל], this leader represents the noble and honored lineage of the House of David [מלבי״ם]. Finally, the foundation is described as absolutely unshakeable. The emphasis here is on a profoundly rooted base that supports the entire structure of the nation and can never be undermined [רש״י, רד״ק, מלבי״ם, מצודות, שד״ל].

The promise concludes by addressing the attitude of the faithful. Because many people doubted the prophetic message, it is made clear that a true believer will not act with impatience. Such a person will not try to force the outcome or demand immediate proof, understanding that the process of salvation takes time and will be preceded by periods of hardship [רש״י, רד״ק, אבן עזרא, מלבי״ם, מצודות]. Another perspective suggests that the believer's response is one of calm confidence. A person who truly relies on God's promise will not experience fear or panic, and will never feel the need to flee from an enemy [שד״ל, ביאור שטיינזלץ]. Furthermore, the ultimate salvation will be so extraordinary that anyone hearing about it might initially hesitate to believe it simply out of sheer amazement [שד״ל].
