Following are a number of back-translations as well as a sample translation for translators of Ecclesiastes 10:14:

• Kupsabiny: “A fool talks too much. A person does not know what is coming in the future and there is no person who can tell us what is going to happen later.” (Source: Kupsabiny Back Translation)
• Newari: “A foolish man just talks and talks.
  No one knows what will happen,
  So no one can tell someone else what will happen later.” (Source: Newari Back Translation)
• Hiligaynon: “And he does- not -stop talking.
  No one ever knows the future, and no one can-tell us (incl.) what will-happen after we died.” (Source: Hiligaynon Back Translation)
• English: “They talk too much/without ceasing.
  None of us knows what will happen in the future,
  or what will happen after we die.” (Source: Translation for Translators)
