Labouring And Gaining Nothing
Solomon observes that “labour is futile,” asking, “What profit hath a man of all his labours under the sun?” He shows that life is an endless cycle—the sun rising and setting, the wind returning to its circuits, the rivers running yet never filling the sea. All things are wearisome; the eye is not satisfied with seeing, nor the ear with hearing. Under the sun, life becomes monotonous, tiring, and without lasting satisfaction.
