The Bible with Sources Revealed (2003) is a book by American biblical scholar Richard Elliott Friedman dealing with the process by which the five books of the Torah came to be written. Friedman follows the four-source Documentary Hypothesis model, but differs significantly from Julius Wellhausen's model in several respects. Most notably, Friedman agrees with Wellhausen on the date of the Deuteronomist (the court of Josiah, c. 621 or 622 BC), but places the Priestly source at the court of Hezekiah; his sequence of sources therefore runs Jahwist-Elohist-Priestly-Deuteronomist. Like Wellhausen, he sees a final redaction in the time of Ezra, c. 450 BC.
