Following are a number of back-translations as well as a sample translation for translators of Isaiah 41:22:

• Kupsabiny: “Let the idols come
  and let them, too, predict what is going to happen.
  Let them just say what shows/explains what has passed
  so it can be known what caused it to happen like that.
  Let them show what will happen.” (Source: Kupsabiny Back Translation)
• Newari: “O idols, tell us what will happen,
  tell us about your former prophecies
  So that we may think them
  and know how they were fulfilled if or not.
  Or what is about to happen — tell us that information.” (Source: Newari Back Translation)
• Hiligaynon: “You (plur.) come-near and tell us (excl.) what will-happen in the future. Tell us (excl.) what have- you (plur.) -spoken before that will-happen so-that we (excl.) can-think if this was-fulfilled. Tell us (excl.) what will-happen in the future so-that we (excl.) will-know that you (plur.) are gods. You (plur.) do good-(thing) or bad-(thing) so-that we (excl.) will-be-amazed and terrified of you (plur.).” (Source: Hiligaynon Back Translation)
