Ecclesiastes 1:16–17

16 I said to myself, “See, I have amassed wisdom far beyond all those who were over Jerusalem before me,p and my mind has thoroughly graspedG wisdom and knowledge.” 17 I applied my mind to know wisdom and knowledge,q madness and folly;r I learned that this too is a pursuit of the wind.s
