Ecclesiastes is a book of the Hebrew Bible and the Christian Old Testament, traditionally attributed to King Solomon but likely written by an unknown author named "Kohelet" or "Qoheleth," meaning "Teacher" or "Preacher." It is part of the Wisdom literature and presents a reflective, often skeptical exploration of the meaning of life, human toil, the limitations of wisdom, and the inevitability of death. The book repeatedly uses phrases like "Vanity of vanities" and "there is nothing new under the sun" to express life's apparent futility. Despite its skeptical tone, it concludes by emphasizing the importance of fearing God and keeping His commandments as life's true purpose. The work is structured as a narrative journey of wisdom and reflection, imparting that while human efforts and knowledge are limited, joy in simple gifts and reverence for God are essential.
