Following are a number of back-translations as well as a sample translation for translators of Isaiah 13:22:

• Kupsabiny: “Hyenas shall be howling where their houses are
  and jackals shall be seen in the beautiful houses.
  There is a day when Babylon is destroyed,
  and no days will be added for them to repent.’” (Source: Kupsabiny Back Translation)
• Newari: “There in the fortress and the palace
  the sound of little jackals and foxes howling [lit.: crying out] will be heard resounding.
  Babylon’s time has come near,
  now it has no more time.” (Source: Newari Back Translation)
• Hiligaynon: “The animals who are like dogs will-howl in the watch-towers and palaces of Babilonia. The end of Babilonia is now soon, it will- no-longer -take-long.” (Source: Hiligaynon Back Translation)
• English: “Hyenas will howl in the ruined towers,
  and jackals/wolves will make their dens in the ruins of the palaces that were previously very beautiful.
  The time when Babylon will be destroyed is very near;
  Babylon will not exist much longer.” (Source: Translation for Translators)
