Ecclesiastes is a work of wisdom reflection voiced mainly by Qoheleth, “the Teacher” or “Assembler,” and framed by a narrator who introduces and evaluates his sayings. Qoheleth is presented as a son of David and king in Jerusalem, a literary voice that evokes Solomon; Jewish and Christian tradition identified him with Solomon, while most modern scholars date the book much later, often to the Persian or Hellenistic period. Through autobiography, observation, proverbs, and poetry, Qoheleth tests work, pleasure, wealth, wisdom, justice, and mortality “under the sun.” His recurring word hebel—literally vapor—can suggest brevity, futility, or enigma. The book counsels grateful enjoyment of God's gifts while denying human control over outcomes. Canonically, it checks easy confidence in wisdom and lets Scripture confront life's limits, ending with the narrator's call to fear God and keep God's commandments.
The Preacher states his thesis — all is vanity — surveys the endless cycles of nature and history that return to their starting point, and conducts a royal experiment in wisdom, pleasure, and achievement. Each avenue is investigated and each is found to be *hebel*: vapor, mist, breath.
The Preacher's famous poem of seasons establishes that time is in God's hands, not human ones. He observes the problem of labor without legacy, the value and limit of companionship, and the dangers of vows made in worship. Throughout, the tension between the futility of grasping and the goodness of receiving shapes the argument.
The Preacher confronts the hardest cases: wealth that cannot be enjoyed, the long life that ends badly, wisdom that cannot guarantee outcomes, and the one fate that comes for all. Yet threaded through every observation is the recurring call to receive the present gift — eat your bread with joy, for God has already approved what you do.
The Preacher's closing movement: practical wisdom amid uncertainty, the call to act despite not knowing outcomes, an allegory of human aging and the fading of life's powers, and the frame narrator's epilogue — the conclusion of the matter: fear God and keep his commandments.
