Following are a number of back-translations as well as a sample translation for translators of Isaiah 47:8:

• Kupsabiny: “Now listen to this word
  you who liked luxury.
  You sat without longing for anything
  so that you said in your stomach,
  ‘I am the only one, please! No one is like me.
  I shall never be a widow
  and the children shall never die from me.’” (Source: Kupsabiny Back Translation)
• Newari: “So, O, [you] who live, being engrossed in pleasure,
  who live with no concern for your own security,
  who keep on thinking in your heart, I am, ‘there is no one like me.
  I will never become a widow [lit.: like one [whose] husband has died].
  or lose my children — pay attention to the words!’ ” (Source: Newari Back Translation)
• Hiligaynon: “Therefore now listen to this, you (sing.) who are fond of pleasure and thinks that you (sing.) will- not -be-harmed. You (sing.) say to yourselves that you (sing.) are the God, and there is no other. You (sing.) think that you (sing.) will never be a widow or lose any children.” (Source: Hiligaynon Back Translation)
