Following are a number of back-translations as well as a sample translation for translators of Isaiah 59:16:

• Kupsabiny: “He saw that no one would rescue people
  and was surprised because no one intervened.
  So, he will use this strength
  to save them getting victory.” (Source: Kupsabiny Back Translation)
• Newari: “The LORD did not see anyone at all who would help the oppressed ones.
  And in seeing that not even a single [person] among [them] would intercede [lit.: make requests], he was amazed.
  After that he saved them with his right arm,
  and he delivered them by his righteousness.” (Source: Newari Back Translation)
• Hiligaynon: “He was surprised of what he saw that there was not even one who helped-out the ones-who-oppressed. Therefore by-means of his power he saved them, and his righteousness has-helped him.” (Source: Hiligaynon Back Translation)
