Following are a number of back-translations as well as a sample translation for translators of Isaiah 10:7:

• Kupsabiny: “But the king of Assyria does not know those things,
  he does not know that I am using him.
  He has his own plans
  wanting to destroy many nations.’” (Source: Kupsabiny Back Translation)
• Newari: “But this is not his desire,
  and he does not have thoughts like that in his mind.
  He does have it in mind, however,
  to destroy many nations.” (Source: Newari Back Translation)
• Hiligaynon: “But the king of Asiria will- not -know that he is- only -being-used by the LORD. He thinks that he is- just -destroying the many nations.” (Source: Hiligaynon Back Translation)
