Julius Wellhausen (1844–1918) famously developed the “Documentary Hypothesis” that separates the texts of the Hebrew Bible into four strands of composition: J (Jahwist, after the name it uses for the Israelite God—Yahweh [Jahweh in German]), E (Elohim, after the name for God this strand uses), P (Priestly Code) and D (for the author of Deuteronomy). As Wellhausen observed, neither J nor E place any restrictions on where a sacrifice may be offered. Hence J and E must date to a time before the reign of King Hezekiah (727–698 B.C.E.), who centralized religious worship in the Jerusalem Temple.
