Following are a number of back-translations as well as a sample translation for translators of Isaiah 48:16:

• Kupsabiny: “Please come nearer here where I am and hear this word.
  I have spoken words to you from long ago
  and I am not hiding myself.
  I was present when these words started.’
  So, today God and his Spirit has sent me.” (Source: Kupsabiny Back Translation)
• Newari: “Come before me and you listen to this matter!
  From the first time I made this proclamation
  I have not spoken in secret.
  When time comes for something to happen, I am there to make happen.
  Now, the LORD has sent me,
  with his sprit.” (Source: Newari Back Translation)
• Hiligaynon: “You (plur.) come-near to me and listen to this: From the beginning I have- not -spoken in secret, and in the times that what I had-spoken had-happened, I am there.’
  And now the Lord GOD and his Spirit sent me to tell this message:” (Source: Hiligaynon Back Translation)
