Whether studied in anticipation of Yom Kippur or used as a guide for personal and professional life, the insights revealed here will be invaluable to all entrepreneurs, creditors, debtors, employers, employees, producers, and consumers. The viduy, or confessional, is the central prayer on Yom Kippur, the Day of Atonement. Recited both silently and by the cantor, the viduy is a confession of sins committed both individually and as a community. Each line of the prayer begins with al chet shechatanu, “for the sin which we have committed.” A major theme of the viduy is social immorality and unethical behavior. In Al Chet: Sins in the Marketplace, Meir Tamari, a renowned authority in the field of Jewish business ethics, explores the viduy specifically as it relates to the business world.
