What are four sources of the documentary hypothesis?

The documentary hypothesis identifies four main sources that contribute to the composition of the Pentateuch: the Yahwist (J), which uses the name Yahweh for God; the Elohist (E), which prefers the term Elohim; the Deuteronomist (D), primarily associated with the book of Deuteronomy; and the Priestly source (P), which focuses on rituals, laws, and genealogies. These sources reflect different theological perspectives and historical contexts, often woven together in the final text. Scholars analyze language, style, and thematic elements to discern these distinct contributions.
