Following are a number of back-translations as well as a sample translation for translators of Isaiah 57:16:

• Kupsabiny: “I will not continue to scold my people
  and I will not continue to be angry all days,
  because it could make these people whom I created and gave life
  faint/become very weak.” (Source: Kupsabiny Back Translation)
• Newari: “I will not be making accusations forever,
  I will not be angry forever,
  so that the hearts of people I have created
  do not become discouraged because of me.” (Source: Newari Back Translation)
• Hiligaynon: “The truth is, I will- not -oppose or will-get-angry forever/[lit. until whenever], for if I will-do this, the people whom I have-created will-die.” (Source: Hiligaynon Back Translation)
