Ecclesiastes 4:5

3 But better than both is he who has not yet existed, who has not seen the evil that is done under the sun.

4 I saw that all labor and success spring from a man’s envy of his neighbor. This too is futile and a pursuit of the wind.

The fool folds his hands and consumes his own flesh.

6 Better one handful with tranquility than two handfuls with toil and pursuit of the wind.

7 Again, I saw futility under the sun.

Do read the surrounding verses too, because the context often says more than a single verse.
