A profound prophetic vision looks toward a future where all of humanity will unite to recognize and serve God. Even if the nations of the world do not currently listen, God has issued an absolute decree that His kingdom will eventually be known across the entire earth [שד״ל].
To establish the certainty of this future, God swears by His own great and eternal name [מלבי״ם, אבן עזרא]. The primary approach among commentators is that this oath represents an absolute decree that cannot be canceled under any circumstances. A true and binding law has been spoken by God, and He will never retract it [מצודת דוד, רד״ק]. This decree is rooted in truth and justice [אבן עזרא, ביאור שטיינזלץ], though it is also viewed as an expression of divine kindness and a free gift to humanity [שד״ל]. The emphasis on this kindness reveals a crucial principle about divine decrees: while prophecies of doom can be overturned if people repent, God's promises for good and grace are permanent and unchanging [מלבי״ם]. It also serves as an assurance that God is always ready and willing to accept anyone who chooses to return to Him [רש״י].
The core of this divine promise is that in the End of Days, all nations will completely abandon their idol worship and accept the authority of God's kingdom alone [מצודת דוד, רד״ק]. There will be an absolute and permanent submission to Him, symbolized by a universal kneeling. Following this recognition, every person will take an oath to accept God, pray only to Him, serve Him, and never again mention the names of other gods [רד״ק, מלבי״ם].
On a deeper, more internal level, this vision is connected to the cycle of life and the mystery of reincarnation. Through this lens, the act of kneeling represents the day of a person's death, while the act of swearing refers to the day of birth, a time when the soul is made to swear that it will live a just life. The sequence of death preceding birth alludes to the cycle of souls returning to this world. A person is bound by this oath to pursue righteousness because, even if they appear entirely good to themselves and to the world, they must maintain deep humility. They cannot know what hidden sins they may carry from a previous life that they have returned to correct [חומת אנך].
