תנ״ך אויף קהלת 4:9

And I turned to cause my heart to despair over all the toil wherein I had toiled under the sun [(so that I would toil no more)].

And I saw all the "toil" [i.e., transgressions] and all the perfection of deed [(motivated not by fear of Heaven, but)] by the envy of one man for another — this, too, is vanity and breaking of spirit.

The fool [(the wicked one)] folds his hands [(in sloth and eats from theft)], and he "eats his flesh" [(on the day of judgment, witnessing the glory of the righteous and his own undoing)].
