Following are a number of back-translations as well as a sample translation for translators of Isaiah 64:5:

• Kupsabiny: “You help those who rejoice in doing truth/justice
  and those who think of/remember you and follow your words.
  You were angry with us because we disobeyed,
  and we continued in sin.” (Source: Kupsabiny Back Translation)
• Newari: “Those who find joy in doing what is right, who remember your ways,
  you come to help them.
  But You were angry because we continued to sin against him
  How will it ever be possible for us to be saved?” (Source: Newari Back Translation)
• Hiligaynon: “You (sing.) accept the one-who-is-glad to do right and follows your (sing.) ways. But you (sing.) are angry with us (excl.) for we (excl.) continue to disobey your (sing.) ways. Therefore how can- we (excl.) -be-saved?” (Source: Hiligaynon Back Translation)
