Following are a number of back-translations as well as a sample translation for translators of Isaiah 8:10:

• Kupsabiny: “You shall all make plans,
  but your actions/words are useless.
  You shall agree in your preparations
  but (they) shall not come to pass,
  because God is with us.” (Source: Kupsabiny Back Translation)
• Newari: “Make plans for yourselves, but they will not succeed.
  Talk as much as you want about them but none of them will succeed,
  for God will be with us.” (Source: Newari Back Translation)
• Hiligaynon: “Whatever you (plur.) are-planning against us (excl.), this will- not -be-successful, because God is with us (excl.).” (Source: Hiligaynon Back Translation)
• English: “You can prepare for what you will do to attack Judah,
  but what you plan to do will not happen!
  You will not succeed,
  because God is with us!” (Source: Translation for Translators)
