8:9 While applying my mind to everything that happens in this world, I have seen all this:
Sometimes one person dominates other people to their harm.
8:16 When I tried to gain wisdom
and to observe the activity on earth –
even though it prevents anyone from sleeping day or night –
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.
