Zephaniah has this chant of thanksgiving. The daughters of Zion were to sing out loud. The daughters of Jerusalem were to rejoice and exult with their whole hearts. Yahweh had taken away his judgments against them, since he had forgiven them. On top of that, Yahweh had turned away all their enemies. Yahweh was now the new king of Israel in their midst. Thus, they had no reason to fear any disasters anymore.
Yahweh, via Jeremiah, wants everyone to sing out loud and be glad for Jacob. They should shout out with joy as they proclaim and praise Yahweh. The people should ask Yahweh to save the remnant of its people. Yahweh was going to return all his people from the lands of the north, as well as from all over the earth, wherever they were. This would include the blind and the lame, women with children and those expecting. Everyone would come together in a great gathering of people as they returned home.
