4:8 A man who is all alone with no companion,
he has no children nor siblings;
yet there is no end to all his toil,
and he is never satisfied with riches.
He laments, “For whom am I toiling and depriving myself of pleasure?”
This also is futile and a burdensome task!
9:12 Surely, no one knows his appointed time!
Like fish that are caught in a deadly net, and like birds that are caught in a snare –
just like them, all people are ensnared at an unfortunate time that falls upon them suddenly.
12:5 and they are afraid of heights and the dangers in the street;
the almond blossoms grow white,
and the grasshopper drags itself along,
and the caper berry shrivels up –
because man goes to his eternal home,
and the mourners go about in the streets –
