Jeremiah 25:30
Therefore prophesy thou against them all these words, and say unto them, The LORD shall roar from on high, and utter his voice from his holy habitation; he shall mightily roar upon his habitation; he shall give a shout, as they that tread the grapes, against all the inhabitants of the earth.
The Lord roaring from on high and uttering His voice from His holy habitation is His speaking with mighty, overwhelming power from heaven in judgment against all the inhabitants of the earth. When He speaks, His voice brings a shaking of the heavens and the earth, and the earth shakes at His speaking. In swift-coming judgment for hardened disobedience, His shout of wrath is drunk as a cup of the wine of divine wrath, first by Jerusalem and the cities of Judah and the kings thereof, then by Pharaoh king of Egypt with his servants and princes and all his people and many other nations of earth until God's purpose is fulfilled. The roar means a complete breaking of the people and the city, like a potter's earthen bottle dashed to pieces in the valley of the son of Hinnom that cannot be made whole again, bringing upon the city and all her towns all the evil pronounced against it because they hardened their necks.
The Lord rises in power to judge the nations after all people have chosen sides for Christ and His commandments or for apostasy. He has a controversy with the nations and gives the wicked to the sword in decisive judgment. In that judgment every opposing power will be punished, and its power and opposition will finally be ended. The judgment silences those who blaspheme God and avenges the injury done to His faithful servants for the truth's sake, reaching those who persecute them.
The verse applies to the great day of Christ's coming, when the divine power once manifested at Sinai will be shown on a still greater scale. The voice uttered from Jerusalem is the same as the great voice out of the temple of heaven from the throne at the pouring out of the seventh vial, which causes a great earthquake that shakes down the cities of the nations and removes islands and mountains. That voice of God from Jerusalem is distinct from the voice of the Son of God that calls forth the sleeping saints, and it is heard before Jesus descends to awake and gather the elect, because Jesus first leaves the heavenly sanctuary and descends from heaven with His holy angels before His voice and trumpet gather the elect to meet Him in the air. The voice of God heard during the time of trouble, rolling through the earth like thunder, fulfills this picture of the Lord speaking with a mighty voice from heaven. His voice marks the time when the righteous are delivered from those who seek to destroy them: the wicked are terrified, and the saints rejoice because they recognize the voice as God's.
