Ecclesiastes 4:8

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!

Ecclesiastes 9:12

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.

Ecclesiastes 12:5

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 –
