I tried ¹  to understand, examine, and comprehend ²  the role of ³  wisdom in the scheme of things, ⁴  and to understand the stupidity of wickedness ⁵  and the insanity of folly. ⁶ 

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.
