Ecclesiastes 2:10

2:10 I did not restrain myself from getting whatever I wanted;

I did not deny myself anything that would bring me pleasure.

So all my accomplishments gave me joy;

this was my reward for all my effort.

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.
