Following are a number of back-translations as well as a sample translation for translators of Ecclesiastes 7:16:

  or even to be very wise.
  Why would you deceive yourself?” (Source: Kupsabiny Back Translation)
• Newari: “Since it is like that, don’t be too righteous,
  and don’t be too wise either.
  Why destroy yourself?” (Source: Newari Back Translation)
• Hiligaynon: “[You (sing.)] do not be-overly good or wise/smart. If you (sing.) do that, you (sing.) are just destroying yourself.” (Source: Hiligaynon Back Translation)

  and do not think that you are very wise,
  because if you think those things, you will destroy yourself.” (Source: Translation for Translators)
