Zephaniah 2:1-2

Zephaniah called the shameless people of Judah to gather together, evidently in a nationwide public assembly, to repent (cf. Zephaniah 1:6; Joel 2:12-14). They needed to do so before the Lord’s decree to punish them took effect and His burning anger overtook them. Nineveh had repented at the preaching of Jonah, and the Lord relented from judging it. Perhaps He would do the same if the Judeans repented. That day was coming as swiftly as chaff blows before the wind, so they needed to act immediately.
