Following are a number of back-translations as well as a sample translation for translators of Ecclesiastes 2:21:

• Kupsabiny: “How can a person pour all his knowledge or all his wisdom into doing something, and then he leaves it to a person who has not fought for that thing! This is also empty and not good.” (Source: Kupsabiny Back Translation)
• Newari: “For someone, having worked hard with wisdom, insight, and skill must still leave all he has achieved to someone who has not worked hard for these things. This matter is also meaningless. And for him this is certainly a great misfortune.” (Source: Newari Back Translation)
• Hiligaynon: “For even you (sing.) will-toil/work-hard with all your (sing.) wisdom and ability, you (sing.) will- only -leave all what you (sing.) had-labored/toiled-for to the man who had- not labored/toiled-for it. This too has no value, and very bad.” (Source: Hiligaynon Back Translation)
• English: “Some people work wisely and skillfully, using the things that they have learned. But when they die, they leave everything, and someone who has not worked hard acquires those things. And that also seemed to be senseless and caused me to be discouraged.” (Source: Translation for Translators)
