מלאכי, פרק ג׳, פסוק ו׳

The eternal nature of God is deeply intertwined with the eternal survival of the Israelites and the ultimate fulfillment of divine justice. The primary approach among commentators focuses on the permanence of God's promise to His people. God declares that He does not age or alter His will, nor does He change the promises He delivered through the prophets, regardless of how much time passes [רד״ק, ביאור שטיינזלץ, צאינה וראינה]. Because He swore to the forefathers of the nation that He would never completely destroy the Israelites, the descendants of Jacob will never be lost. Unlike other nations that fade and disappear from the stage of history without a trace, the Israelites remain under God's direct care. Just as He exists forever, the nation survives forever, continuing from generation to generation [רד״ק, אבן עזרא, נחל שורק].

This eternal promise shapes a unique system of divine providence and punishment. Since God cannot break His word and wipe out the nation entirely, He administers justice by punishing them little by little in this world. This gradual process prevents their sins from accumulating to a point that would require total destruction. While other nations might suffer a single, devastating blow and vanish completely, the Israelites endure various hardships throughout history but never truly disappear [רש״י, מלבי״ם, אברבנאל].

An additional perspective completes this picture by focusing on personal justice. God maintains that His values remain constant; He has always loved good and hated evil. However, people might observe wicked individuals living long, peaceful lives and mistakenly conclude that they have escaped punishment and that justice no longer exists. The reality is that death is not the final end, and a person does not simply vanish from existence. Souls continue to live on. Those who committed evil and left this world without facing consequences during their lifetimes will ultimately face judgment in the afterlife or during the resurrection of the dead, where they will receive their exact and proper return [רש״י, מצודת דוד, אברבנאל].
