Following are a number of back-translations as well as a sample translation for translators of Jeremiah 33:11:

• Kupsabiny: “people shouting with joy and happiness and others shall ululate in joy at weddings. You (plur.) shall hear people singing/dancing when they bring things to sacrifice giving thanks saying,
  ‘Give (plur.) thanks to God of power
  because he is good
  and he loves people for years and years.’
  I shall bring back blessing to this land as it was before.” (Source: Kupsabiny Back Translation)
• Hiligaynon: “the rejoicing and marrying. (It)-will-be-heard the rejoicing of newlywed(s), and the people who bring offerings of thanksgiving to the temple of the LORD. They will-say, ‘Give-thanks to the LORD Almighty, for he (is) very good. His love is without end.’ Yes, the people will-rejoice for I will-restore the good situation of this land just like before. I, the LORD, (am) the-(one) saying this.’” (Source: Hiligaynon Back Translation)
• English: “some day people will again be happy and laugh. Brides and bridegrooms will again sing joyfully. And many other people will also sing joyfully as they bring their offerings to me to thank me for what I have done for them. They will sing this song:
  ‘We thank you, the Commander of the armies of angels,
  because you are good to us.
  You faithfully love us forever.’
  They will sing that because I will cause the people of this land to be as prosperous as they were before.’” (Source: Translation for Translators)
