Passage
Exult, O daughter of Zion; shout, O Israel; rejoice and be glad with all the heart, O daughter of Jerusalem:
Exult, O daughter of Zion; shout, O Israel; rejoice and be glad with all the heart, O daughter of Jerusalem:
Zephaniah 3:12 And I will leave in the midst of thee an afflicted and poor people, and they shall trust in the name of Jehovah.
Zephaniah 3:13 The remnant of Israel shall not work unrighteousness, nor speak lies; neither shall a deceitful tongue be found in their mouth: but *they* shall feed and lie down, and none shall make them afraid.
Zephaniah 3:14 Exult, O daughter of Zion; shout, O Israel; rejoice and be glad with all the heart, O daughter of Jerusalem:
Zephaniah 3:15 Jehovah hath taken away thy judgments, he hath cast out thine enemy; the King of Israel, Jehovah, is in the midst of thee; thou shalt not see evil any more.
Zephaniah 3:16 In that day it shall be said to Jerusalem, Fear not; Zion, let not thy hands be slack.
The verse centers on "exult", "daughter", "zion", "shout", "israel", "rejoice", "glad", and "heart". It is saying that the verse draws attention to "exult" and "daughter", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 13's "The remnant of Israel shall not work..." into verse 15's "Jehovah hath taken away thy judgments he...", so "exult" and "daughter" 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 "exult" and "daughter" with trust shaped by these words, not by a vague optimism outside the passage.
