The Major Codices

The most substantial witnesses to the Greek Old Testament are three parchment Bibles from late antiquity that transmit the Septuagint in large, carefully copied collections. These codices—Vaticanus (B), Sinaiticus (א), and Alexandrinus (A)—do not begin the story of the Septuagint, but they preserve a mature form of it that had already circulated for centuries. Because Chapters 2–3 established the historical context and the translation’s beginnings, this chapter concentrates on the physical books themselves, their characteristic text, and their bearing on textual criticism. The focus remains on what these codices add to our knowledge of the Greek Old Testament; discussion of later editions and modern critical projects will come in a subsequent chapter.

Codex Vaticanus (B) is a fourth-century C.E. parchment Bible, usually dated about 325–350 C.E. Its script is a disciplined biblical majuscule, written in three columns per page—an economical and elegant format that sets it apart from later two-column biblical codices. Vaticanus preserves the bulk of the Septuagint with noteworthy lacunae, and its text in many books is recognized as exceptionally close to the “Old Greek” where that can be identified. Its Pentateuch and the Former Prophets often exhibit restrained, pre-Hexaplaric readings; in several books its wording appears less touched by later standardizing revisions. As with all late antique codices, Vaticanus contains books beyond the thirty-nine of the Hebrew canon, a reminder that “contents bound together” and “canon” should not be confused. What matters for textual criticism is that the Greek Torah, Prophets, and Writings in Vaticanus consistently provide a sober, conservative witness against which other streams can be measured.

Codex Sinaiticus (א), another fourth-century C.E. parchment Bible (commonly placed c. 330–360 C.E.), is copied in four narrow columns per page. It preserves extensive portions of the Septuagint, though damage and loss have affected parts of its Old Testament. Its text shows a more mixed profile than Vaticanus in several books. In parts of the Prophets and in Daniel, Sinaiticus exhibits Hexaplaric influence—the imprint of Origen’s great third-century C.E. collation (discussed below)—and in some historical books it aligns with forms that reflect later editorial activity toward the Hebrew. This does not lower its value; it simply marks it as a codex that transmits areas where Greek Scripture had been revised. Sinaiticus is also a prime witness to Christian scribal habits such as nomina sacra, in which sacred terms (God, Lord, Jesus, Spirit) are written as reverential abbreviations with a supralinear bar. In Old Testament contexts where the Greek tradition has κύριος for the Tetragrammaton, Sinaiticus follows the established Christian convention of abbreviation. Earlier Greek papyri, as we will see, preserve the Divine Name differently.

Codex Alexandrinus (A), early fifth century C.E. (often dated c. 400–440 C.E.), is copied in two columns per page with a strong, rounded majuscule. Alexandrinus transmits a vast Old Testament collection, including books such as 1–4 Maccabees and the Odes with Psalm 151, and it is a major witness for the Psalter and many historical books. Its textual profile is not uniform. In the Pentateuch it sometimes stands nearer to Vaticanus than to other lines; in the historical books its text frequently agrees with what scholars term the Antiochene or Lucianic tradition; and in the Prophets it often reflects a text that has undergone some revision toward the Hebrew. The value of Alexandrinus lies precisely in its breadth and its alternative readings: where Vaticanus is sparse or damaged, Alexandrinus often preserves the passage; where the text of Kings and Chronicles is divided among families, Alexandrinus supplies a carefully copied representative of the Antiochene form.

These three codices are not interchangeable duplicates. They embody distinct textual currents that were already well developed by the fourth and fifth centuries C.E. Vaticanus often preserves an earlier, less revised Greek; Sinaiticus frequently carries areas of Hexaplaric correction; Alexandrinus preserves, among other things, a robust Antiochene form in the historical books. When the codices agree against later recensional witnesses, their combined testimony is weighty. When they diverge, they reveal the history of Greek biblical texts after the original translations were made.

Physically, the three codices share traits that matter for the discipline. All are written in scriptio continua, with words run together and sense divisions indicated by spacing, ekthesis (a projecting initial at the left margin), and paragraph marks. All employ nomina sacra with consistency. All were copied by trained hands within professional settings. The quality of the parchment, the disciplined ruling of pages, and the skilled correction show that the text of the Greek Scriptures was handled with care comparable to other great literary works of late antiquity. That care does not eliminate textual variation, but it assures us that variation entered the stream through identifiable channels—recensional work, regional habits, and normal copyists’ slips—rather than through free paraphrase.

For pastors and serious students, it is helpful to think of the codices as complementary rather than competitive. Vaticanus often functions as the most austere measuring rod; Sinaiticus reveals where later standardizing toward the Hebrew left its mark; Alexandrinus gives access to the strong Antiochene form and to readings widely known in the Byzantine East. A sound judgment about a passage weighs these codices in light of their known profiles and then takes account of corroborating evidence from papyri, versions, and—most decisively—Hebrew witnesses. Where all three codices support a Greek reading that also aligns with independent witnesses and clarifies a difficult Masoretic form, the case for an older Hebrew reading strengthens. Where a reading depends on a single codex and can be explained as a recensional adjustment, caution is warranted.

Papyri Evidence

The codices are late in the story’s timeline. Earlier witnesses—papyri and scrolls—anchor the Greek Old Testament in the centuries before the codices were copied and illuminate how Jewish scribes handled the Divine Name and how Greek translation traditions developed. These papyri, often fragmentary, provide decisive snapshots across the second century B.C.E. through the first centuries C.E., confirming that Greek Scripture was read and copied well before Christian codex culture organized it into large parchment books.

Among the earliest continuous witnesses to the Greek Pentateuch are second–first century B.C.E. fragments of Deuteronomy, copied in a straightforward documentary hand rather than a later calligraphic majuscule. A central set is the group often called Papyrus Fouad 266 (first century B.C.E.), which transmits portions of Deuteronomy and conspicuously writes the Divine Name not as κύριος but in Hebrew characters within the Greek text. This practice aligns with a sober reverence for Jehovah’s Name already present in Jewish scribal traditions. The presence of the Tetragrammaton in these Greek lines confirms that early Jewish Greek Scripture did not “erase” the Name; it preserved it in a visually distinct form, reminding Greek readers that the Name is holy. The surrounding Greek is literal and careful, matching the translation habits described in Chapter 3.

A separate and important early witness is a Greek Leviticus fragment from Qumran (4Q120), commonly dated to the first century B.C.E. This copy renders the Divine Name with the Greek transliteration IAO (ΙΑΩ), a practice that also attests reverence through a specialized form rather than a generic surrogate. The appearance of IAO in a Jewish Greek Leviticus demonstrates that Jewish scribes knew more than one convention for representing the Name in Greek contexts. Later Christian copies would standardize κύριος (commonly abbreviated as a nomen sacrum), but the earlier practice—either Hebrew letters or IAO—must be weighed when evaluating quotations and when considering how Greek Scripture would have sounded when read aloud in pre-Christian synagogues.

The Greek Minor Prophets Scroll from Naḥal Ḥever (8HevXII gr), dated to the late first century B.C.E. or early first century C.E., offers additional clarity. The scroll’s Greek text exhibits a marked tendency to conform to a Hebrew form that stands closer to the later Masoretic tradition—one reason this Greek stream is often called “kaige” (on which more below). In this scroll the Divine Name is written in ancient Hebrew characters within the Greek text, continuing the pattern of visual reverence. The scroll is particularly valuable because it shows a Jewish revision of Greek toward the Hebrew current that would eventually dominate. That revision is not a Christian activity; it shows Jewish scribes aligning Greek copies with the Hebrew base their communities recognized. For textual criticism, the scroll demonstrates both the vitality of the Greek tradition and the discipline imposed by synagogue and study.

Other papyri scattered across the Oxyrhynchus and Fayum finds confirm that the Greek Old Testament circulated widely in Egypt in the first centuries B.C.E. and C.E. Portions of Genesis, Exodus, Numbers, Job, Psalms, and prophetic books appear in diverse hands. Some are school texts with scribal exercises; others are private copies with liturgical punctuation; still others are fragments of well-made scrolls. The variety of hands and contexts shows that Greek Scripture was not a rarefied library piece. It was copied, read, and used in communal and personal settings. These papyri often predate the Hexaplaric activity of the third century C.E. and so can preserve readings that help us reconstruct the Old Greek or identify later revisions by contrast.

The papyri also supply technical evidence about the format of Greek Scripture before the codex era dominated. Many witnesses are scrolls, copied in columns with regular rulings and with paragraphing that signals narrative breaks or poetic lines. Marginal markers and ekthesis sometimes indicate the start of new sections. Where lectional signs appear, they reveal synagogue usage. All of this aids the textual critic in determining how a phrase or clause should be read where later codices differ in punctuation or word division, because early practice provides a control on possibilities.

For the treatment of the Divine Name—of special interest to faithful readers who honor Jehovah’s Name—the papyri and early scrolls are decisive. They show that Jewish Greek Scripture did not default to κύριος in the earliest period. Instead, it preserved the Name in Hebrew characters or in the transliteration IAO. Later Christian transmission moved toward κύριος as a reverential surrogate, written with the well-known nomen sacrum. When teaching Old Testament passages in which the Tetragrammaton occurs, it is therefore historically appropriate to use “Jehovah,” recognizing that the earliest Greek witnesses sought to guard the Name’s sanctity even as they translated the surrounding words into Greek.

In sum, the papyri anchor the Septuagint’s history in the centuries immediately after the translations were made. They confirm synagogue use, demonstrate consistent literal habits, reveal early forms of the Divine Name in Greek copies, and expose revisional activity toward the Hebrew in certain lines. They also keep our estimates of the codices realistic: by the time Vaticanus, Sinaiticus, and Alexandrinus were copied, the Greek tradition had already experienced centuries of faithful copying and, in places, controlled correction.

Textual Families and Recensions

Because the Septuagint is a collection of translations produced by different hands over time, its history naturally includes distinct textual families—lines of transmission that share characteristic readings—and recensions, deliberate revisions of the Greek designed to accomplish specific aims. A pastor or student who knows the main families can navigate differences responsibly without being unsettled. What follows is an orderly map of the principal currents: the Old Greek base, the Hexaplaric tradition, the Antiochene (Lucianic) revision, and the Egyptian stream often labeled Hesychian. We will also note the kaige/Proto-Theodotion movement that revises the Greek toward a Hebrew form close to the later Masoretic text.

The term Old Greek refers to the earliest recoverable translation for a given book—the form produced in the centuries B.C.E. before later systematic revisions. In some books, the Old Greek is well preserved in Vaticanus or in early papyri; in others it must be reconstructed from scattered witnesses because later recensions displaced it. Daniel provides the clearest case: the Old Greek Daniel survives, but in many Christian manuscripts it was replaced by the version associated with Theodotion (second century C.E.), which stands closer to the Hebrew text used in his day. Where the Old Greek can be identified with confidence, it offers a direct line to the earliest Jewish translation choices. It is therefore a primary focus when weighing the Septuagint’s testimony.

The Hexaplaric tradition arises from Origen’s monumental Hexapla, a third-century C.E. project in which he set the Hebrew text and several Greek versions (Aquila, Symmachus, the Old Greek, and Theodotion) in six parallel columns, marking with critical signs where the Old Greek lacked words present in the Hebrew or where it contained wording not found in the Hebrew. Origen’s concern was not to replace the Old Greek but to annotate it so that readers could see where Hebrew and Greek differed. Later copyists and revisers, however, copied the Old Greek column with Origen’s asterisks and obeli and, in some cases, incorporated the marked additions into the Greek text while losing the signs themselves. The result is a recognizable Hexaplaric text—a Greek form that includes material brought in to match the Hebrew, often with readings borrowed from the versions in Origen’s other columns. Sinaiticus in parts of the Prophets reflects this Hexaplaric influence; so do many later manuscripts in certain books. When a passage looks unusually aligned with the standard Hebrew and bears vocabulary typical of Aquila or Theodotion while still transmitting the Old Greek base, Hexaplaric revision is a reasonable diagnosis.

The Antiochene or Lucianic tradition is associated with Lucian of Antioch (martyred 312 C.E.). This line appears most prominently in the historical books (Samuel–Kings and often Chronicles) and in some parts of the Prophets. Its readings tend toward smoothing and harmonization across parallel passages, and it occasionally preserves expansions that reflect a desire to unify the narrative. Alexandrinus transmits many Lucianic readings in the historical books, and a cluster of later manuscripts in the Byzantine East continues the tradition. The Lucianic revision does not erase the Old Greek; it edits it along recognizably Antiochene lines. Where Vaticanus and the Lucianic witnesses diverge in the historical books, their difference often highlights the choice between a more austere earlier form and a later attempt to iron out perceived difficulties by cross-referencing. Both deserve a hearing; the critic assigns greater weight to the earlier form unless the Lucianic reading has strong external corroboration.

An Egyptian stream, sometimes labeled Hesychian after Hesychius of Alexandria (d. early fourth century C.E.), is visible especially in Isaiah and some other Prophets. The label identifies a group of readings characteristic of Egyptian transmission that present a text distinct from the Antiochene and Hexaplaric forms. Whether one attributes this to a single editor or to a regional tradition, the practical upshot is the same: in certain books the Egyptian copies preserve a Greek form with consistent local habits. When Vaticanus and an Egyptian-aligned witness concur against Antiochene and Hexaplaric forms, the agreement is noteworthy because it likely reflects an older Alexandrian-type Greek.

The kaige/Proto-Theodotion movement names a Jewish revision of the Greek toward the Hebrew text that would later be stabilized in the Masoretic tradition. It begins in the late first century B.C.E. and continues into the first century C.E. The nickname “kaige” comes from a characteristic rendering of certain Hebrew particles, but the phenomenon is broader: the Greek is adjusted to match Hebrew morphology and vocabulary with higher fidelity, sometimes adopting Semiticizing equivalents where the Old Greek had freer renderings. The Greek Minor Prophets Scroll from Naḥal Ḥever is the prime witness to this tendency. Theodotion’s second-century C.E. version of Daniel continues the same impulse, bringing the Greek closer to the Hebrew text known in his day. When a Septuagint passage shows unusually tight alignment with the standard Hebrew and uses formulas typical of these revisers, it likely stands within the kaige/Proto-Theodotion trajectory. Recognizing this helps the critic avoid treating a later revision as if it were the earliest Jewish understanding of the verse.

These families and recensions interact differently in different books. In the Pentateuch, the text preserved in Vaticanus and in early papyri is often close to the Old Greek with minimal later correction; Hexaplaric activity is lighter, though it is not absent. In the Twelve Minor Prophets, the Naḥal Ḥever scroll demonstrates a strong kaige revision, and many later copies continue in that line, while earlier Old Greek phrasing must be recovered from indirect witnesses and from places where later revisers left the base untouched. In the historical books, Alexandrinus is frequently the main Lucianic witness; Vaticanus commonly preserves a non-Lucianic, earlier form; and the critic weighs the two. In Isaiah, an Egyptian (Hesychian-labeled) text stands out; in Daniel, the Theodotionic form dominates Christian transmission but the Old Greek remains accessible for comparison.

Origen’s marks deserve special attention because misunderstandings of them have caused confusion. The asterisk in a Hexaplaric text signals words added to the Greek to equal the Hebrew length; the obelus flags Greek words with no counterpart in the Hebrew column. Where later scribes copied the additions but dropped the signs, the resulting text reads as if it were an original Greek translation that simply happens to match the Hebrew closely. That is why in books with strong Hexaplaric influence a critic must exercise care: the text may look “more literal,” but its literalness can be an artifact of third-century editing rather than of the second-century B.C.E. translator. This does not make Hexaplaric witnesses unreliable; it tells us how to use them. If the aim is to recover the earliest Greek translation, one must discount evident Hexaplaric additions; if the aim is to see how late antique Jews and Christians read Greek Scripture alongside Hebrew, Hexaplaric copies are invaluable.

The interplay of these families shows that the Septuagint’s history is not chaotic. It is controlled and intelligible. Jewish translators produced a careful Old Greek; Jewish revisers in the last centuries B.C.E. and the first centuries C.E. tightened the Greek toward the Hebrew; Christian scholars in the third and fourth centuries C.E. annotated, aligned, and, in places, adopted those alignments for ecclesiastical use; regional traditions such as the Antiochene line shaped the historical books; Egyptian habits marked particular prophetic texts. At every stage, scribes worked with respect for the text, not with speculative license. This orderly development is why the Septuagint serves textual criticism so well. The critic can identify which family a reading belongs to and then apply the appropriate weight when comparing it with the Masoretic tradition and with other ancient witnesses.

One example will illustrate the method without stepping into topics reserved for later chapters. In 1–2 Kingdoms (Samuel–Kings), Alexandrinus frequently transmits the Antiochene (Lucianic) form, including harmonizations across parallel accounts. Vaticanus, by contrast, often preserves a leaner Greek where difficult readings stand without smoothing. When a verse presents a plus in Alexandrinus that echoes Chronicles against Kings, and Vaticanus lacks it, and there is no support from early papyri or from independent versional witnesses, the most sober judgment is to regard the plus as Lucianic harmonization. Conversely, where Alexandrinus and Vaticanus agree against later Hexaplaric witnesses, and the reading explains the rise of competing forms, their agreement commands strong respect.

Another example comes from Daniel. The widespread Christian preference for Theodotion’s version does not discredit the Old Greek; it informs us that Jewish and Christian readers in the second–fourth centuries C.E. valued a Greek Daniel that matched the Hebrew more tightly. For textual criticism, the Old Greek remains essential when the question concerns the earliest translation choices or the Greek text known to certain New Testament and early Christian authors. For ecclesiastical reading in late antiquity, Theodotion’s form naturally predominated. Recognizing the purpose of each form allows us to use both responsibly.

A final note concerns the Divine Name across these families. As already observed in the papyri, the earliest Greek copies often preserved Jehovah’s Name in Hebrew characters or transliterated IAO. As the codex era advanced and Christian scribal conventions crystallized, κύριος written as a nomen sacrum became standard in Greek Old Testament copies. Hexaplaric, Antiochene, and Egyptian witnesses all transmit this later convention. The shift should not be misconstrued as a denial of the Name; it is a reverential practice within Christian copying. In study and public reading today, fidelity to the Hebrew text recommends that “Jehovah” be used where the Tetragrammaton stands, while recognizing how Greek codices presented the Name in their own scribal tradition.

The net effect of mapping these families is confidence. We can say with clarity where our Greek witnesses stand in relation to the earliest translations, where they have absorbed revisional work, and how they relate to each other. That clarity produces sound judgments when the Septuagint is compared with the Masoretic Text for the restoration of the earliest attainable Hebrew wording. The Septuagint’s manuscript history is not a liability. It is a resource that, when read with knowledge of its families and recensions, helps the church handle Scripture with accuracy.

How the Major Witnesses Work Together in Practice

Because this book is designed for serious churchgoers, pastors, and seminary students, it is useful to describe how one actually uses these witnesses without duplicating later chapters that will treat case studies in detail. The process begins by identifying which textual family the principal Greek witnesses represent for the book in question. If the passage lies in the historical books, one notes that Vaticanus commonly preserves a non-Lucianic form, while Alexandrinus often reflects the Lucianic stream. If the passage lies in Isaiah, one recognizes the strength of the Egyptian line. If the passage lies in the Twelve, one checks for kaige influence. Then one consults any early papyri for the book—especially where they preserve pre-Hexaplaric readings or Divine Name conventions. Having located the Greek evidence within its family, one compares it with the Masoretic reading and looks for convergence with independent witnesses such as the Syriac Peshitta, the Vulgate where it translates Hebrew directly, and Hebrew fragments from the Judean wilderness.

Weight is assigned, not votes counted. A lone Lucianic reading in a book otherwise well preserved in Vaticanus does not override the Masoretic Text. But a pre-Hexaplaric Greek reading supported by early papyri and by a Hebrew fragment against a difficult Masoretic form commands attention. In all of this, the major codices serve as anchor points, the papyri provide early controls, and the families explain why differences appear where they do. This yields decisions that a pastor can explain clearly: “This line of Greek reflects a later revision toward the Hebrew and therefore carries less weight for reconstructing the earliest translation,” or, “This Greek reading appears in our earliest witnesses and aligns with independent evidence; it likely reflects an older Hebrew form.”

Later chapters will examine the Septuagint’s relationship to the Dead Sea Scrolls, the Masoretic tradition, and specific books where differences matter—Jeremiah, Daniel, Esther, and others. They will also describe modern critical editions and their apparatus. To avoid repetition, this chapter has confined itself to the manuscripts themselves: what the big codices are, what the papyri show, and how to recognize the main textual families and recensions. Equipped with this map, the reader can enter later discussions already knowing where the witnesses stand.

The result is ordered confidence. The three great codices provide massive, careful texts; the papyri and early scrolls verify that Greek Scripture was copied and read reverently long before the codices; and the main families make sense of the differences. This is exactly what a reliable manuscript tradition looks like. It grew under the pressure of synagogue use, benefited from the discipline of scholarly collation, and, in God’s providence, now stands ready to help restore the earliest text of the Old Testament while reinforcing the stability of the Hebrew Scriptures entrusted to Israel.
