Following are a number of back-translations as well as a sample translation for translators of Isaiah 66:6:

• Kupsabiny: “Listen! There is uproar/noise in the city.
  There is a voice that comes from the house of God.
  That is the voice of God
  and he is punishing his enemies.” (Source: Kupsabiny Back Translation)
• Newari: “Hear the chattering voices that are coming out from the city!
  Hear the sound coming out from the temple!
  This is the voice of the LORD taking
  suitable revenge on his enemies.” (Source: Newari Back Translation)
