A divine promise of dramatic change and global upheaval creates a sharp contrast between a modest present reality and a grand future. God announces a massive historical intervention that will soon impact all of creation. When addressing the nature of this upcoming event, commentators explore several different paths regarding its scope and timing. One approach focuses on time, suggesting that the event will happen shortly or last only a brief period [ביאור שטיינזלץ]. This might mean the Second Temple itself will stand for a relatively short time [מצודת דוד], or it could hint at the Greek empire, which will rise after the fall of Persia and rule over Israel briefly [רש״י].
A second perspective shifts the focus from time to effort. Bringing about such a massive wonder is a small and easy task for God, especially if the people repent and return to Him [אבן עזרא, רד״ק, מלבי״ם]. Others view this description physically, noting that the Second Temple will be smaller and of lesser value than the First Temple built by Solomon [אברבנאל]. Finally, a spiritual interpretation suggests that the spirit of prophecy currently resting on the people is minimal. They require an additional infusion of wisdom and fear of God to bring about the ultimate redemption [מלבי״ם].
God then promises to shake the heavens, the earth, the sea, and the dry land [מצודת ציון, ביאור שטיינזלץ]. The exact nature and timing of this great shaking is a matter of significant discussion. The primary approach among commentators is that this shaking is a metaphor for the immense honor and miracles Israel will experience during the Second Temple era, particularly the miracles of the Hasmoneans [רש״י, רד״ק, חומת אנך]. In the wake of these events, the nations of the world will recognize the Divine presence and bring offerings of silver and gold to the Temple. This shaking may also refer to the physical splendor of the Temple during the days of Herod. While an actual earthquake did occur during that time, the description of shaking the heavens is understood as a poetic exaggeration [רד״ק].
In stark contrast, some interpret the shaking as a grim warning of the Second Temple's ultimate destruction. According to this view, God will orchestrate a global shockwave where massive armies gather from the ends of the earth, traveling by sea and dry land. They will wage war against Israel until the Temple is destroyed, much like the siege of the Roman legions [מצודת דוד, אברבנאל].
A completely different school of thought rejects the connection to the Second Temple entirely. Looking at historical realities, these commentators argue that the promise will only be fulfilled during the future redemption. In this context, the shaking represents global revolutions [ביאור שטיינזלץ] and an all-out war against the nations during the ingathering of the exiles. This will culminate in the building of a third and final Temple, a place of true peace and honor [אברבנאל]. Similarly, this future shaking will manifest as a literal alteration of the laws of nature, featuring visible signs and wonders in both the heavens and the earth [מלבי״ם].
