Ecclesiastes
Ecclesiastes is one of the Ketuvim ('Writings') of the Hebrew Bible. An unnamed author introduces "The words of Kohelet, son of David, king in Jerusalem" (1:1) and does not use his own voice again until the final verses (12:9–14).
Kohelet proclaims (1:2) "Vanity of vanities! All is futile!" This verse presents the basic existential question with which the rest of the book is concerned. In light of this perceived meaninglessness, he suggests that human beings should enjoy the simple pleasures of daily life, such as eating, drinking, and taking enjoyment in one's work, which are gifts from the hand of God. The book concludes with the injunction to "Fear God and keep his commandments, for that is the duty of all of mankind. Since every deed will God bring to judgment, for every hidden act, whether good or evil.
