Complete 24 books of the Hebrew Bible.
Late 9th or early 10th century CE.
Hebrew Bible codex, not a Greek Bible witness.
Tiberian Masoretic pointing and apparatus.

One of the oldest near-complete Hebrew Bibles, carrying the Masoretic tradition from Tiberias toward modern printed editions.
I. What Is Codex Sassoon?
Codex Sassoon is a Masoretic Hebrew Bible codex copied toward the end of the ninth century or the beginning of the tenth, making it one of the oldest surviving near-complete copies of the Hebrew Scriptures. It contains the traditional 24 books of the Hebrew Bible on parchment, arranged in a single volume. The text is supplied with Tiberian vocalization, cantillation marks, and the concise Masorah Parva and fuller Masorah Magna notes that characterized the Ben Asher school.
The codex takes its name from its former owner, the great twentieth-century collector David Solomon Sassoon; in 2023 it was acquired for public display by Alfred H. Moses. Its broader significance lies in its antiquity and completeness. While the Aleppo Codex and Leningrad Codex are more famous, Codex Sassoon belongs to the same narrow circle of early medieval Hebrew Bibles that carry the Masoretic tradition from Tiberias into the modern printed editions.
"The Masoretes created a text of remarkable stability, and manuscripts like Codex Sassoon show how that stability was maintained across centuries of copying.", Emanuel Tov, Textual Criticism of the Hebrew Bible
II. Place in the Broader Manuscript Tradition
Codex Sassoon matters to the study of biblical manuscripts because it testifies to the same scribal culture that produced the great Greek and Latin codices of the Greek Bible. The early medieval centuries were the great age of the pandect, the all-inclusive Bible codex. Christian scribes in Greek, Latin, and Syriac were assembling complete Bibles at roughly the same time that Jewish scribes in the Land of Israel and Iraq were producing complete Hebrew Bibles furnished with pointing and Masorah. The technologies were shared, even when the Scriptures differed.
Seen in this light, Codex Sassoon is a Jewish counterpart to Codex Sinaiticus and Codex Vaticanus. Those Greek codices gather the Old and Greek Bibles in a single volume. Sassoon gathers the Hebrew Bible alone. All three depend on the parchment codex, the scribal profession, and the conviction that sacred books deserve to be copied with extraordinary care. The comparison is instructive: it reminds us that Jewish and Christian textual cultures developed in parallel, sometimes in conversation and sometimes in rivalry, but always with the biblical text at the center.
III. Distinction from Greek Bible Manuscripts
It is important not to confuse Codex Sassoon with the Greek uncial codices discussed elsewhere on this site. Sassoon contains no Gospels, no Acts, no Epistles, and no Apocalypse. Its language is Hebrew, not Greek. Its text is the Masoretic Bible, not the Septuagint or the Greek Bible. The designation "codex" refers only to its physical format, not to its contents. For students of Greek Bible transmission, Sassoon is relevant as context, not as evidence.
That context is not negligible. The Hebrew Bible was the Scripture of Jesus and the apostles. The textual stability visible in Codex Sassoon is the end point of a tradition that Jesus read, quoted, and fulfilled. When the Greek Bible writers cite the Hebrew Bible, they are drawing on the same stream of Hebrew text that the Masoretes would later fix. Codex Sassoon therefore illuminates the background against which the Greek Bible arose, even though it does not preserve the Greek Bible itself.
IV. Brief Significance
Codex Sassoon is a monument of medieval Jewish Bible production. Its survival underscores the durability of the Masoretic tradition and the skill of the scribes who transmitted it. For the Christian reader it is a reminder that the Hebrew Bible did not float free of textual history. It was guarded, letter by letter, by Jewish communities whose work the congregation inherited. For the textual scholar it is another data point in the reconstruction of the Hebrew Bible, comparable in importance to the Aleppo and Leningrad codices.
Because this site includes notes on Greek Bible manuscripts, Codex Sassoon is listed here for completeness and comparison. Its proper home is in the history of the Hebrew Bible, the Masoretes, and the Jewish scribal tradition.
