Genesis, the first book of the Hebrew Bible and Christian Old Testament, takes its name from the Greek word for origin or beginning. In Hebrew it is called Bereshit (In the beginning), after its opening word. The book spans an immense narrative arc, moving from the creation of the cosmos to the death of in , and serves as the prologue to the entire biblical story.
Genesis divides naturally into two unequal parts. Chapters 1 to 11, often called the primeval history, address universal questions of human existence through stylized narratives of creation, fall, flood, and the dispersion of nations. Chapters 12 to 50, the ancestral or patriarchal history, narrow the focus to a single family chosen as the vehicle of divine blessing for all peoples: and , and , and his wives and sons, and finally .
As the foundational document of Israel's identity, Genesis establishes the central theological premises that the rest of the canon will develop: one God who creates and sustains the world, the dignity and brokenness of humanity, divine promise and covenant, and the gradual unfolding of a redemptive plan through chosen but flawed human agents. Its literary craftsmanship, theological depth, and influence on Western religion and literature are difficult to overstate.
Authorship & Dating
Traditional view: Jewish and Christian tradition has long ascribed Genesis, along with the other four books of the Pentateuch, to Moses. This view is reflected in later biblical references to the Torah of Moses and was the dominant assumption in Judaism and Christianity through the medieval period.
Scholarly view: Modern critical scholarship generally treats Genesis as a composite work assembled from multiple sources and traditions over several centuries. The classical Documentary Hypothesis identifies Yahwist (J), Elohist (E), and Priestly (P) strands, though many scholars now prefer more flexible models that recognize ongoing redaction and the integration of older oral material. There is broad agreement that the final form took shape in the exilic or post-exilic period.
Dating: While the traditions behind Genesis are far older, most scholars date the book's final compilation to the sixth or fifth century BCE, during or shortly after the Babylonian exile. Earlier source material may reach back to the monarchic period or earlier.
Historical Context
The events Genesis narrates are set in the Bronze Age world of the ancient Near East, with the patriarchal narratives traditionally placed in the early to middle second millennium BCE. The cultural backdrop includes Mesopotamian city-states, Canaanite settlements, and a Late Bronze Age that was a regional superpower. Genesis interacts with this milieu by sharing motifs with Mesopotamian creation and flood epics such as Enuma Elish and the Gilgamesh and Atrahasis traditions, while sharply reconfiguring them around monotheistic and ethical convictions.
The book's final composition, however, reflects a much later setting. The catastrophe of the Babylonian exile in the sixth century BCE forced Israel to rearticulate its identity apart from temple, land, and king. In this context Genesis functioned as a foundational charter, anchoring Israel's existence in the purposes of the creator God and the irrevocable promises made to , , and .
Genesis also engages the religious environment of the ancient world polemically. By portraying the sun, moon, and sea creatures as creations rather than deities, and by insisting that humanity collectively bears the divine image, it implicitly critiques the cosmologies and social hierarchies of surrounding cultures. The patriarchal stories likewise emphasize a God who is not bound to a single shrine but accompanies his people on their journeys.
