Documentary Hypothesis

The documentary hypothesis, (DH) (sometimes called the Wellhausen hypothesis), holds that the Torah was derived from originally independent, parallel and complete narratives, which were subsequently combined into the current form by a series of redactors (editors). The number of these is usually set at four, but this is not an essential part of the hypothesis.

The hypothesis was developed in the 18th and 19th centuries from the attempt to reconcile inconsistencies in the biblical text. Biblical scholars, using source criticism, eventually arrived at the theory that the Torah was composed of selections woven together from separate, at times inconsistent, sources, each originally a complete and independent document. By the end of the 19th century it was generally agreed that there were four main sources, combined into their final form by a series of redactors, R. These four sources came to be known as the Yahwist, or Jahwist, J (J being the German equivalent of the English letter Y); the Elohist, E; the Deuteronomist, D, (the name comes from the Book of Deuteronomy, D's contribution to the Torah); and the Priestly Writer, P.

Julius Wellhausen's contribution was to order these sources chronologically as JEDP, giving them a coherent setting in the evolving religious history of Israel, which he saw as one of ever-increasing priestly power. Wellhausen's formulation was:

• the Yahwist source ( J ) : written c. 950 BC in the southern Kingdom of Judah.
• the Elohist source ( E ) : written c. 850 BC in the northern Kingdom of Israel.
• the Deuteronomist ( D ) : written c. 600 BC in Jerusalem during a period of religious reform.
• the Priestly source ( P ) : written c. 500 BC by Kohanim (Jewish priests) in exile in Babylon.

While the hypothesis has been increasingly challenged by other models in the last part of the 20th century, its terminology and insights continue to provide the framework for modern theories on the origins of the Torah.
