The Lord will gather all things and disperse the wicked, extending His hand over Judah and Jerusalem to punish those who have turned aside from following Him, bringing a day of wrath, tribulation, and anguish. Those who do not seek Him and live justly will be destroyed, and various nations, including Philistia, Moab, and Ammon, will be punished, along with powerful cities like Assyria and Ethiopia. However, a remnant of Israel will remain faithful and be saved, and the Lord will ultimately restore Jerusalem to renown and praise among the nations.
