Leningrad Codex

The oldest complete Hebrew Bible manuscript in existence and the textual foundation for virtually all modern scholarly editions and translations of the Old Testament.

The Leningrad Codex, cataloged as B19A (also known by its full shelf mark EBP I B 19 A), is the oldest complete manuscript of the entire Hebrew Bible. Its colophon states that it was completed in Cairo, Egypt, in 1008–1009 CE by the scribe Samuel ben Jacob, who based his work on manuscripts corrected by Aaron ben Moses ben Asher, the foremost Masorete of the 10th century. This connection to the Ben Asher tradition gives the codex its authority: while the Aleppo Codex, vocalized by Aaron ben Asher himself, is considered textually superior, its loss of approximately 40% of its pages means that for large portions of the Hebrew Bible — including most of the Pentateuch — the Leningrad Codex is the oldest and best available witness.

The manuscript consists of 491 leaves (982 pages) of vellum, written in three columns per page for most of the text. The Torah sections and some other portions are in two columns. The calligraphy is careful and professional, executed in a square Hebrew script with the full apparatus of Tiberian vowel points, cantillation marks (te'amim), and Masoretic notes (Masorah parva in the margins, Masorah magna at the tops and bottoms of pages, and Masorah finalis at the ends of books). The codex opens with decorative carpet pages — geometric patterns rendered in gold, brown, and violet that recall the carpet pages of medieval Islamic manuscripts and Irish Gospel books.

The history of the codex's journey to Russia is tied to the career of Abraham Firkovich (1787–1874), a Karaite Jewish scholar and collector who amassed one of the largest private collections of Hebrew manuscripts in the 19th century. Firkovich acquired the codex (along with thousands of other manuscripts) during his travels through the Middle East and the Crimea. After his death, his collection was purchased by the Imperial Public Library in St. Petersburg (now the National Library of Russia), where the Leningrad Codex remains today.

The codex first came to the attention of Western biblical scholars when Paul Kahle examined it in the 1920s while preparing the third edition of Rudolf Kittel's Biblia Hebraica (BHK). Kahle recognized that the Leningrad Codex represented the best available complete witness to the Tiberian Masoretic Text and persuaded Kittel to adopt it as the base text for BHK3, published in 1937. This was a revolutionary decision: previous editions of the Hebrew Bible had been based on late medieval printed editions (the Second Rabbinic Bible of Jacob ben Hayyim, 1524–1525), not on a single early manuscript.

Every subsequent major critical edition of the Hebrew Bible has continued to use the Leningrad Codex as its base text. The Biblia Hebraica Stuttgartensia (BHS), published in 1977 and the most widely used scholarly Hebrew Bible of the 20th century, reproduces the Leningrad Codex with a critical apparatus noting variants from other manuscripts, the Dead Sea Scrolls, and the ancient versions. The Biblia Hebraica Quinta (BHQ), the new edition currently being published in fascicles, continues to use the Leningrad Codex as its base text, supplemented by the Aleppo Codex where that manuscript survives.

The textual relationship between the Leningrad Codex and the Aleppo Codex is complex. Both claim descent from the Ben Asher tradition, and they agree in the vast majority of their readings. However, in several hundred places they differ, sometimes in vocalization, sometimes in cantillation, occasionally in the consonantal text itself. These differences may reflect different stages in the development of the Ben Asher textual tradition, or they may indicate that the Leningrad Codex's claim to be based on Ben Asher manuscripts is not entirely accurate. Moshe Goshen-Gottstein argued that the Leningrad Codex is not a pure Ben Asher text but shows influence from the rival Ben Naphtali tradition in some of its vocalization patterns.

Despite these scholarly debates, the Leningrad Codex's practical importance is unmatched. When a modern English, German, French, or Spanish Bible translates the Old Testament, the Hebrew text being translated is almost always the text of the Leningrad Codex as presented in BHS. This single manuscript, written by a single scribe in Cairo over a thousand years ago, stands behind every major translation of the Hebrew Bible in use today — the NIV, ESV, NASB, NRSV, Luther Bible, and many others.

The codex was fully photographed in the 1980s for the Ancient Biblical Manuscript Center in Claremont, California, and a color facsimile was published in 1998. High-resolution digital images are available through the National Library of Russia and various digital humanities projects. The Westminster Leningrad Codex, a digital transcription of the manuscript, is freely available and forms the basis for many Bible software programs and online Hebrew Bibles.

• Oldest complete manuscript of the entire Hebrew Bible, dated to 1008–1009 CE by its colophon
• Written by scribe Samuel ben Jacob in Cairo, based on Aaron ben Asher's corrections
• Base text for BHK3, BHS, and BHQ — the standard critical editions used by scholars and translators worldwide
• 491 leaves of vellum with full Tiberian vocalization, cantillation marks, and Masoretic apparatus
• Opens with decorative carpet pages in gold, brown, and violet geometric patterns
• Collected by Abraham Firkovich in the 19th century; held by the National Library of Russia since 1863
• Differs from the Aleppo Codex in several hundred readings, possibly reflecting Ben Naphtali influence
• Underlies virtually all modern Old Testament translations (NIV, ESV, NASB, NRSV, Luther Bible, etc.)

The Leningrad Codex is, in practical terms, the Hebrew Bible. When modern readers open virtually any translation of the Old Testament, the text they read derives from this manuscript. From "In the beginning God created the heaven and the earth" (Genesis 1:1) to "lest I come and smite the earth with a curse" (Malachi 4:6), the consonantal text, the vowels, and the cantillation marks of the Leningrad Codex define the standard Hebrew Bible text. The codex's Masoretic apparatus — the thousands of marginal notes counting letters, marking unusual spellings, and recording variant traditions — represents the culmination of centuries of scribal labor dedicated to preserving every detail of the biblical text. This meticulous care fulfills the spirit of Psalm 119:89: "For ever, O LORD, thy word is settled in heaven." The Masoretes saw themselves as guardians of a divine text, and their work in the Leningrad Codex is the most complete surviving embodiment of that devotion. The codex's completeness — containing every book from Genesis through Chronicles in the traditional Jewish ordering — makes it the essential reference point for understanding the shape of the Hebrew canon. The canonical order (Torah, Prophets, Writings) preserved in the Leningrad Codex is the arrangement that Jesus himself would have known, referenced in Luke 24:44: "all things must be fulfilled, which were written in the law of Moses, and in the prophets, and in the psalms, concerning me."
