Following are a number of back-translations as well as a sample translation for translators of Isaiah 47:5:

• Kupsabiny: “God is saying,
  ‘You are sitting in a dark place and going to darkness,
  oh, city of the Chaldeans.
  You shall no longer be called
  a king/ruler of countries.” (Source: Kupsabiny Back Translation)
• Newari: “O Babylon, capital of the great land of Babylonia,
  You sit in silence! Go into a dark place!
  From now on you will not be called
  the female ruler of the Kingdoms. ” (Source: Newari Back Translation)
• Hiligaynon: “The LORD still said, ‘[You (sing.)] Babilonia, sit peacefully in the dark place. You (sing.) will- no longer -be-called queen of the kingdoms.” (Source: Hiligaynon Back Translation)
