 By the middle of the 20th century, Wellhausen's documentary hypothesis, the tradition history of Gunkel and Noth, and the Biblical archaeology of William F. Albright, who claimed to have found physical proof of the 2nd millennium BC origins of Genesis, Exodus, and the other books of the Pentateuch, had merged to form a dominant paradigm, or consensual view, of the origins of the Pentateuch.It was this paradigm that was challenged by Whybray's "The Making of the Pentateuch".
