Following are a number of back-translations as well as a sample translation for translators of Isaiah 45:8:

• Kupsabiny: “Let righteousness pour down from heaven
  and let the land receive that righteousness.
  Salvation and victory shall grow.
  I am God who has done it.’” (Source: Kupsabiny Back Translation)
• Newari: “O heavens above, let my righteousness rain down.
  Let clouds shower it down.
  Let the earth be open, and let salvation and righteousness prosper.
  I, the LORD, have created this."” (Source: Newari Back Translation)
• Hiligaynon: “I will-give victory with righteousness, like the giving of the heavens or the dark-cloud of rain. The people in the world will-accept/receive it. Salvation and victory with righteousness will-spread-out like a plant that grows. I, the LORD, will-do this.” (Source: Hiligaynon Back Translation)
