Following are a number of back-translations as well as a sample translation for translators of Isaiah 64:7:

• Kupsabiny: “No one cries to you to come to aid (them)
  and no one is searching for you to aid (them).
  You hid yourself from us
  and allowed our sins to kill us.” (Source: Kupsabiny Back Translation)
• Newari: “There is not even one person who takes your name,
  no one tries to take you,
  for you have hidden your face from us,
  and you left us in the power of our sins.” (Source: Newari Back Translation)
• Hiligaynon: “No one among us (excl.) who really takes refuge in you (sing.) and tries to hold you (sing.). For you (sing.) turned-your-back from us (excl.), and you (sing.) let- us (excl.) -die because of our (excl.) sins.” (Source: Hiligaynon Back Translation)
