Following are a number of back-translations as well as a sample translation for translators of Ecclesiastes 6:10:

• Kupsabiny: “Everything that happens, has already been prepared and it is known how a person is and it is known that a weak person cannot oppose/argue with one who has power.” (Source: Kupsabiny Back Translation)
• Newari: “Whatever exists, its name has been determined,
  and who a man is has been understood.
  You will not be able to stand against one who is stronger than you.” (Source: Newari Back Translation)
• Hiligaynon: “God has- already -destined everything in the-past, and he already knew/knows what we (incl.) will-be. So we (incl.) can- not -argue with God about our (incl.) future/fate, for he is more stronger than us (incl.).” (Source: Hiligaynon Back Translation)
• English: “All the things that exist on the earth have been given names.
  And everyone knows what people are like,
  so it is useless to argue with someone (OR, with God)
  who is stronger than we are.” (Source: Translation for Translators)
