Following are a number of back-translations as well as a sample translation for translators of Jeremiah 51:41:

• Kupsabiny: “(People) boasted greatly of Babylon all the time!
  But it is surely a surprise when it will be captured!
  Yes, it will be so terrible
  in the eyes of other nations!” (Source: Kupsabiny Back Translation)
• Hiligaynon: “How Babilonia was fallen, the nation being-praised by the whole world! What had-happened to her was-terrifying to look at!” (Source: Hiligaynon Back Translation)
• English: “People all over the earth now honor/praise Babylon;
  they say that it is a great city.
  But I will cause it to become a place about which people of all nations are horrified.” (Source: Translation for Translators)
