Ecclesiastes 2:21

For he sees that even wise men die; The fool and the senseless alike perish And leave their wealth to others.

I have seen that every labor and every success of the work is the result of jealousy between a man and his neighbor. This too is vanity and striving after wind.

There was a certain man without a second man, having neither a son nor a brother, yet there was no end to all his labor. Indeed, his eyes were not satisfied with riches—“And for whom am I laboring and depriving myself of good?” This too is vanity, and it is a grievous endeavor.
