“It is a strange fact that we have never known with certainty who produced the book that has played such a central role in our civilization,” writes Friedman, a foremost Bible scholar. From this point he begins an investigation and analysis that reads as compellingly as a good detective story. Focusing on the central books of the Old Testament—Genesis, Exodus, Leviticus, Numbers, and Deuteronomy—he draws upon biblical and archaeological evidence to make a convincing argument for the identities of their authors. In the process he paints a vivid picture of the world of the Bible—its politics, history, and personalities. The result is a marvel of scholarship that sheds a new and enriching light on our understanding of the Bible as literature, history, and sacred text.
