4 Again, I saw that for all toil and every skillful work a man is envied by his neighbor. This also is vanity and grasping for the wind.
5 The fool folds his hands and consumes his own flesh.
6 Better a handful with quietness than both hands full, together with toil and grasping for the wind.
7 Then I returned, and I saw vanity under the sun:
8 There is one alone, without companion: He has neither son nor brother. Yet there is no end to all his labors, nor is his eye satisfied with riches. But he never asks, “For whom do I toil and deprive myself of good?” This also is vanity and a grave misfortune.
[Verse 4] can be taken to mean either that doing excellent work makes others jealous, or that the worker just wants to do well because he is envious of what others have. — Grace, page 1172
