Following are a number of back-translations as well as a sample translation for translators of Jeremiah 8:15:

• Kupsabiny: “We had thought that we would find peace,
  but nothing good came.
  We thought that a chance to be healed/saved would arrive
  but we found terror.” (Source: Kupsabiny Back Translation)
• Hiligaynon: “We (incl.) desired for peace, but no peace came. We (incl.) desired for healing/goodness, but terror came.” (Source: Hiligaynon Back Translation)
• English: “We hoped/desired that things would go well for us,
  but things have not gone well.
  We hoped that bad things would not happen to us any more,
  but only things that terrify us are happening to us.” (Source: Translation for Translators)
