Zephaniah 2:1-2

Amplified Bible

2 Gather yourselves together [in repentance], yes, gather [in submission],
O nation without shame,
² 
Before the decree takes effect [and the time for repentance is lost]—
The day passes like the chaff [whirled by the wind]—
Before the burning and fierce anger of the Lord comes upon you,
Before the day of the wrath of the Lord comes upon you.
