Following are a number of back-translations as well as a sample translation for translators of Deuteronomy 32:6:

• Kupsabiny: “Oh you stupid people,
  don’t you know to obey God?
  Is he not your father who created you?
  Is he not the one who takes care of you?” (Source: Kupsabiny Back Translation)
• Newari: “O you people who are fools and have no common sense,
  What! Is this the way
  that you repay the LORD?
  Is He not the one who created you,
  and the one who caused you to come into existence, your father,
  creator of your universe?” (Source: Newari Back Translation)
• Hiligaynon: “Is this what you (plur.) are going to repay the LORD?
  You are very foolish and lack of understanding.
  Is he not your (plur.) Father who created you (plur.)?” (Source: Hiligaynon Back Translation)
• English: “You foolish and senseless people,
  is this the way that you should repay Yahweh for all that he has done for you?/this is certainly not the way that you should repay Yahweh for all that he has done for you.
  He is your father; he created you ;
  he caused you to become a nation.” (Source: Translation for Translators)
