What does Jeremiah 33:11 mean?

the sound of joy and laughter will return—the voices of brides and grooms, and people bringing thank offerings to my house, saying, 'Give thanks to the Lord of hosts, for he is good; his love lasts forever.' I'll bring back the people from captivity and restore the land as it was before, says the Lord. Jeremiah 33:11 - Modern Text Bible

(God promises that happiness, celebration, and worship will return to Jerusalem, reversing the current sorrow.)
