Ecclesiastes 2:19

2:19 Who knows if he will be a wise man or a fool?

Yet he will be master over all the fruit of my labor

for which I worked so wisely on earth!

This also is futile!

Ecclesiastes 5:2

5:2 Do not be rash with your mouth or hasty in your heart to bring up a matter before God,

for God is in heaven and you are on earth!

Therefore, let your words be few.
