The verse centers on "gather", "sorrow", "solemn", "assembly", "thee", "burden", "upon", and "reproach". It is saying that the verse draws attention to "gather" and "sorrow", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 17's "Jehovah thy God is in the midst..." into verse 19's "Behold at that time I will deal...", so "gather" and "sorrow" belong inside that flow. 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 "sorrow" with trust shaped by these words, not by a vague optimism outside the passage.
