AI Unlocks Biblical Authorship Secrets with Cutting-Edge Analysis

In a groundbreaking study, researchers have harnessed artificial intelligence (AI) to uncover hidden clues about the authorship of the Hebrew Bible’s oldest books, shedding new light on a centuries-old debate. Led by Duke University and published on June 3, 2025, the study analyzed the Enneateuch—the first nine books of the Hebrew Bible—using advanced linguistic techniques and a custom AI model. The findings reveal distinct writing styles, pointing to multiple authors or scribal groups, and open new avenues for analyzing ancient texts.

How AI Was Used

The research team, comprising mathematicians, archaeologists, linguists, and computer scientists, developed an AI-driven methodology to analyze word frequency patterns in 50 chapters of the Enneateuch. They focused on three scribal corpora: the Priestly source (P), the Deuteronomistic History (DtrH), and the oldest layers of Deuteronomy (D). The process involved several key steps:

1. Lemma Extraction: The team extracted base forms (lemmas) of Hebrew words using the Open Scriptures Hebrew Bible project, standardizing variations to enhance pattern detection.

2. Dictionary Formation: A dictionary of 1,447 unique lemmas and n-grams (word sequences) was created to capture linguistic nuances.

3. Text Descriptor Construction: Each chapter was converted into a frequency table, counting lemma occurrences.

4. Discrepancy Calculation: Using a statistical method called Higher Criticism (HC), the AI calculated discrepancies in word usage between texts, identifying subtle differences without predefined assumptions.

5. Authorship Attribution: The model assessed the likelihood of a chapter belonging to one of the three corpora, achieving an 84% accuracy rate in matching scholarly classifications.

The AI identified three distinct writing styles, confirming traditional scholarly divisions while revealing surprises, such as the Ark Narrative in 1 Samuel, which didn’t align with any of the three corpora, suggesting an unknown author.

Implications of the Discovery

This AI-driven approach has profound implications for biblical scholarship and beyond:

• Resolving Authorship Debates: The study provides statistically significant evidence of distinct linguistic fingerprints, supporting the idea that multiple authors or groups contributed to the Bible over centuries. For instance, the Priestly texts were markedly different from Deuteronomy and DtrH, aligning with scholarly consensus on their later composition.

• Uncovering Hidden Layers: The identification of an unaffiliated Ark Narrative suggests previously unrecognized authors, prompting new questions about the Bible’s formation.

• Interdisciplinary Collaboration: The fusion of AI, statistics, and biblical studies demonstrates the power of combining humanities with technology, offering a model for future research.

Applications to Other Texts

The methodology’s versatility extends far beyond the Bible. Shira Faigenbaum-Golovin, the study’s lead mathematician, noted its potential for authenticating historical documents, such as verifying Abraham Lincoln’s writings or detecting forgeries. The approach can be applied to any ancient or modern text with sufficient length, including:

• Historical Manuscripts: Analyzing word patterns to attribute authorship in fragmented or disputed texts, such as ancient Greek or Roman works.

• Literary Forgeries: Detecting inconsistencies in style to authenticate or debunk documents claiming historical significance.

• Cross-Cultural Studies: Comparing linguistic patterns across different ancient languages to trace cultural influences or authorship in texts like the Dead Sea Scrolls.

The team plans to apply this method to other ancient texts, potentially revolutionizing how scholars approach authorship attribution in historical documents.

A New Era for Textual Analysis

This study marks a significant milestone in digital humanities, blending AI’s precision with the nuanced expertise of biblical scholars. By providing interpretable, statistically robust results, the methodology not only deepens our understanding of the Hebrew Bible but also sets a precedent for analyzing other historical texts. As Thomas Römer, a co-author, stated, “Our method accurately identifies differences in simple words like ‘no’ or ‘king,’ offering a new tool to address disputed matters in biblical studies.” This symbiosis of science and scripture is poised to unlock further secrets of the ancient world.
