8:17 then I discerned all that God has done:
No one really comprehends what happens on earth.
Despite all human efforts to discover it, no one can ever grasp it.
Even if a wise person claimed that he understood,
he would not really comprehend it.
9:3 This is the unfortunate fact about everything that happens on earth:
the same fate awaits everyone.
In addition to this, the hearts of all people are full of evil,
and there is folly in their hearts during their lives – then they die.
