I have examined all this by wisdom; I said, “I am determined ¹  to comprehend this” ²  – but it was beyond my grasp. ³ 

For a man may do his work with wisdom, knowledge, and skill; however, he must hand over ¹  the fruit of his labor ²  as an inheritance ³  to someone else who did not work for it. This also is futile, and an awful injustice! ⁴ 

I decided ¹  to carefully ²  and thoroughly examine ³  all that has been accomplished on earth. ⁴  I concluded: ⁵  God has given people ⁶  a burdensome task ⁷  that keeps them ⁸  occupied. ⁹ 

I thought deeply ¹  about the effects of ²  indulging ³  myself ⁴  with wine (all the while ⁵  my mind was guiding me ⁶  with wisdom) ⁷  and the effects of ⁸  behaving foolishly, ⁹  so that I might discover what is profitable for people to do on earth during the few days of their lives.
