Following are a number of back-translations as well as a sample translation for translators of Isaiah 65:25:

• Kupsabiny: “Jackals/wild dogs and lambs shall graze in one place,
  a lion shall eat grass like the cow
  and the snakes shall eat dust.
  Nothing shall wound or destroy anything
  on my mountain of Zion that is holy.
  I am God who has spoken.’” (Source: Kupsabiny Back Translation)
• Newari: “The wolf and the little lamb will eat, being together in one place,
  and as for the lion, it will eat straw like an ox.
  But as for the snake’s food, it will be dust.
  In all my holy mountain they will neither do harm nor destruction.
  The LORD has spoken."” (Source: Newari Back Translation)
• Hiligaynon: “The fierce wolves will-eat together with the sheep. The lions will-graze straw like the cows. And the snakes will- no-longer -bite. No one will-harm or destroy my holy mountain. I, the LORD, (am) the-(one) saying this.’” (Source: Hiligaynon Back Translation)
