Ecclesiastes 2:17

2:17 So I loathed life because what

happens on earth seems awful to me;

for all the benefits of wisdom are futile – like chasing the wind.

Ecclesiastes 8:9

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.

Ecclesiastes 9:5-6

9:5 For the living know that they will die, but the dead do not know anything;

they have no further reward – and even the memory of them disappears.

9:6 What they loved, as well as what they hated and envied, perished long ago,

and they no longer have a part in anything that happens on earth.
