Envy and jealousy are the private parts of the human soul. Perhaps the comparison can be extended.

The desire to create continually is vulgar and betrays jealousy, envy, ambition. If one is something one really does not need to make anything - and one nonetheless does very much. There exists above the productive man a yet higher species.

Wherever good fortune enters, envy lays siege to the place and attacks it; and when it departs, sorrow and repentance remain behind.

The flower which is single need not envy the thorns that are numerous.

Envy wounds with false accusations, that is with detraction, a thing which scares virtue.

The higher you ascend, the smaller you appear to the eye of envy. But most of all they hate those who fly.
