Authorship and Date

First Samuel is an anonymous book. Nothing in the text identifies its author, and the title "Samuel" refers to the book's primary character, not its writer. Samuel himself dies in chapter 25, which means the book as a whole could not have been composed by him. Understanding who wrote it, when, and out of what sources requires engaging with the Deuteronomistic History hypothesis, one of the most influential proposals in twentieth-century biblical scholarship.

Traditional Attribution

Jewish tradition, preserved in the Babylonian Talmud (tractate Baba Batra 14b-15a), attributes the books of Samuel to Samuel himself, with portions completed by the prophets Nathan and Gad. This attribution connects to passages within the text that mention written records maintained by Samuel, Nathan, and Gad (1 Chronicles 29:29), suggesting that later editors understood these figures as the sources behind the narrative. The tradition has a certain logic: Samuel is present in the early chapters, Nathan and Gad appear later in the story, and the books collectively span the period these figures are said to have been active.

Critical scholarship does not find this attribution historically defensible. The narrative extends well beyond the deaths of all three figures. The text shows signs of being written from a perspective removed in time from the events it describes, using phrases like "to this day" that imply a later vantage point. The theological framework shaping the narrative matches a literary and theological tradition associated with the period of the late monarchy and the exile, centuries after Samuel, Nathan, and Gad.

The Deuteronomistic History

The most influential framework for understanding the authorship of First Samuel is the Deuteronomistic History hypothesis, proposed by the German scholar Martin Noth in 1943. Noth argued that the books of Deuteronomy, Joshua, Judges, Samuel, and Kings form a single continuous literary composition, shaped by a coherent theological perspective rooted in the covenant theology of Deuteronomy. On this reading, a single author or school, writing during the exile (around 587 to 540 BCE), compiled and edited older source materials into a sweeping theological history of Israel from the entry into Canaan through the destruction of Jerusalem.

The Deuteronomistic framework is visible in First Samuel in several ways. Key transitions are marked by lengthy speeches in which characters reflect on Israel's history and its covenant obligations, a pattern found throughout the Deuteronomistic corpus. The evaluation of kings and leaders follows the theological criteria established in Deuteronomy. The book's portrayal of Samuel as a prophet who announces both promise and judgment aligns with the Deuteronomistic understanding of prophetic function.

Noth's hypothesis has been refined and debated extensively since 1943. Frank Moore Cross argued in 1973 for two editions of the Deuteronomistic History: an earlier edition produced during the reign of Josiah (late seventh century BCE) and a later exilic revision. Richard Friedman, Walter Brueggemann, and others have proposed further modifications. The debate continues, but the broad consensus that the books of Samuel were shaped by Deuteronomistic editors working with older materials remains the dominant position in critical scholarship.

Sources Behind the Text

Even within the Deuteronomistic framework, scholars identify distinct source traditions that the editors incorporated into the final text. These include what scholars call the Ark Narrative (chapters 4 through 6 and part of 2 Samuel 6), which has a distinctive literary style and appears to have circulated independently. There is also a cycle of stories associated with Samuel's early life and prophetic activity, a court history focused on the rise of David, and what appear to be two separate accounts of Saul's selection as king that were combined rather than harmonized. The presence of these distinct strands is one piece of evidence for the composite nature of the book.

Some material within the book is widely regarded as preserving genuinely old traditions, possibly originating in the tenth or ninth century BCE, close in time to the events described. The Song of Hannah in chapter 2 is considered by many scholars to be an early composition that was placed in its current context by later editors, since its content does not closely match Hannah's personal situation but fits the broader themes of the book. Whether these older traditions accurately reflect historical events, or have been shaped by the theological purposes of later editors, is a question the text itself cannot settle.

Date of Final Composition

The most widely accepted scholarly position places the final form of First Samuel in the exilic period, roughly the sixth century BCE, with the possibility of significant editorial work during the reign of Josiah in the late seventh century. The reference to "the kings of Judah" in 1 Samuel 27:6 is sometimes cited as evidence of a perspective that knows the divided monarchy as historical fact, suggesting a date no earlier than the late tenth century for at least some of the material. The theological concerns evident throughout the book, particularly the use of Israel's failure to keep the covenant as an explanation for national catastrophe, fit most naturally in the context of the Babylonian exile, when the destruction of Jerusalem demanded theological accounting.

There is no single date that applies to the entire book. It is better understood as a text with a long compositional history, drawing on older oral and written traditions, shaped by editorial activity over several centuries, and reaching something like its present form in the exilic or early post-exilic period.
