The presence of God's glory radiating from the Sanctuary creates a powerful impact across the world. As His power becomes visible in Jerusalem, the leaders of the nations are moved to recognize His greatness and respond by bringing tribute and offerings [מצודת ציון, רש״י, מאירי].
The primary approach among commentators is that this global response is directly triggered by the Divine revelation within the city. When foreign kings witness God's glory dwelling in the Sanctuary, they are naturally inspired to present gifts [רש״י, מצודת דוד]. This inspiration is fueled by the visible strength flowing outward from His dwelling place to protect the entire city. It is this exact power that saved Jerusalem from its enemies, standing in sharp contrast to the damage suffered by other nearby cities. Observing that Israel's survival and strength stem entirely from God dwelling among them is what ultimately drives these rulers to bring their offerings to Him [רד״ק, ביאור שטיינזלץ]. Furthermore, these tributes are not merely brought toward the city, but are delivered directly into the Sanctuary itself [מאירי].
While the focus is largely on offerings brought to God, another perspective suggests that the target of these distant tributes is actually King David, as foreign nations bring gifts to honor his earthly leadership [אבן עזרא].
Adding a deeper historical and symbolic layer, the Sanctuary can also represent the righteous individual. Specifically, it points to the patriarch Jacob, whose spiritual presence is permanently etched above the heavenly Jerusalem. Viewed through this lens, the tribute brought by the kings of the world in the future is not a new offering for which they deserve thanks. Instead, it is simply the return of the historical gift that Jacob once gave to Esau [אלשיך].
