Following are a number of back-translations as well as a sample translation for translators of Jeremiah 50:39:

• Kupsabiny: “So animals like jackals, hyenas shall live (there),
  and birds like owls
  so that people shall never again live in that land
  from generation to generation.” (Source: Kupsabiny Back Translation)
• Hiligaynon: “‘Babilonia will- just -be-inhabited by wild animals, fierce/cruel and wild dogs, and owls. People will- never -live there again until forever.” (Source: Hiligaynon Back Translation)
• English: “Soon only hyenas and other wild creatures will live there;
  and it will be a place where owls live.
  People will never live there again;
  it will be uninhabited forever.” (Source: Translation for Translators)
