Following are a number of back-translations as well as a sample translation for translators of Isaiah 66:4:

• Kupsabiny: “So, I shall punish those people,
  I shall send a disaster to crush (them),
  because no one responds when I am calling,
  (they) refuse to listen to me when I speak to (them)
  They have done bad things in my eyes
  and accept/love things that do not make me happy.’” (Source: Kupsabiny Back Translation)
• Newari: “So I will deal with them harshly,
  I will bring matters to them that will instill a sense of fear.
  For when I called, no one answered.
  When I called, no one was concerned.
  What was not good in my eyes, exactly that they did.
  And what was not pleasing to me, exactly that they did."” (Source: Newari Back Translation)
• Hiligaynon: “Aside from those, I will-send them punishment which will- really -make- them -terrify. For when I called, they did- not -answer; when I spoke, they did- not -listen. They did wickedness before me, and whatever I am not pleased-with is-what they do.’” (Source: Hiligaynon Back Translation)
• English: “When I called out to you,
  you did not answer.
  When I spoke, you did not pay attention.
  You did many things that I say are evil;
  you chose to do things that I did not like.
  So now I will punish you by causing you to experience the things that you are very afraid of.’” (Source: Translation for Translators)
