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. [2]
