Following are a number of back-translations as well as a sample translation for translators of Ecclesiastes 8:1:

• Kupsabiny: “How is a wise person? Who knows how things are? Wisdom makes a person smile and opens his worried face.” (Source: Kupsabiny Back Translation)
• Newari: “Who else is like the wise man?
  Who knows the meaning of these things?
  Wisdom causes a man’s face to smile,
  and even changes [his] angry face.” (Source: Newari Back Translation)
• Hiligaynon: “No one can-be-like a wise/knowledgeable man, who knows how-to-explain things. The wisdom/knowledge of man brightens his face, and takes-away his frowning.” (Source: Hiligaynon Back Translation)
• English: “I will tell you about those who are truly wise
  with the result that they can explain why everything happens.
  Being wise enables people to be happy
  and enables them to smile.” (Source: Translation for Translators)
