Passage
Gather yourselves together, yea, gather together, O nation that hath no shame;
Gather yourselves together, yea, gather together, O nation that hath no shame;
Zephaniah 2:1 Gather yourselves together, yea, gather together, O nation that hath no shame;
Zephaniah 2:2 before the decree bring forth, [before] the day pass as the chaff, before the fierce anger of Jehovah come upon you, before the day of Jehovah`s anger come upon you.
Zephaniah 2:3 Seek ye Jehovah, all ye meek of the earth, that have kept his ordinances; seek righteousness, seek meekness: it may be ye will be hid in the day of Jehovah`s anger.
The verse centers on "gather", "yourselves", "together", "nation", "hath", and "shame". It is saying that the verse draws attention to "gather" and "yourselves", so its meaning should be read from those terms before moving to application.
The next verse adds "before the decree bring forth before the...", so "gather" and "yourselves" should be read forward into that movement. In Zephaniah context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "gather" and "yourselves" with trust shaped by these words, not by a vague optimism outside the passage.
