Following are a number of back-translations as well as a sample translation for translators of Isaiah 48:11:

• Kupsabiny: “I am doing like that for my own sake,
  I shall save you because of the honor that I have.
  Why should I allow that I am being mocked?
  I do not leave/abandon my greatness for/to another.” (Source: Kupsabiny Back Translation)
• Newari: “What I will do, I will do for my own sake.
  I will not allow my name to be defamed.
  nor will I allow my glory to be shared with other gods.” (Source: Newari Back Translation)
• Hiligaynon: “I will-do this for my honor. I will- not really -allow that I will-be-put-to-shame and the other god will-be-honored.” (Source: Hiligaynon Back Translation)
