Future historical and economic shifts will completely transform the global balance of power. The wealth of the world will flow directly to Israel, bringing with it a profound spiritual awakening. The vivid imagery of nursing from foreign nations and their kings is universally understood as a metaphor. It paints a picture of absorbing the goodness, abundance, and resources of the world [רש״י, רד״ק, מצודת ציון].
There are different perspectives on exactly how this wealth will be transferred. One approach suggests that it will arrive in the form of gifts, treasures, and spoils that foreign leaders and nations will bring either willingly or as the result of a victory [שד״ל, ביאור שטיינזלץ]. Another perspective views this flow of wealth as a fixed financial tax. Since kings act as central hubs collecting the riches of their lands, Israel drawing this wealth from them functions like a tax. This dynamic points to a position of superiority and control rather than standard trade relations [אבן עזרא, מלבי״ם].
On a deeper spiritual level, absorbing the spoils of the nations represents a victory in the heavenly court. During the exile, the sins of Israel were often the result of foreign influence. Therefore, God transfers the guilt of these wrongdoings to the spiritual representatives of the nations. Taking the wealth of foreign kings is actually a symbol of the merit and salvation gained when the responsibility for past sins is placed back upon those who caused them [אהבת יהונתן].
The ultimate purpose of this immense abundance and global upheaval is deep spiritual clarity. When these events unfold, Israel will immediately recognize that they are not mere historical coincidences, but the direct actions of God [מצודת דוד]. God's divine providence in this process operates through two distinct channels. His role in saving represents the general repair of the entire world, while His role in redeeming points to a private, unique redemption specifically intended for Israel [מלבי״ם]. All of this flows from a profound divine strength, highlighting God's absolute rule and authority over His people [מצודת ציון, ביאור שטיינזלץ].
