Manuscripts of Hebrew Scriptures. There are possibly 6,000 manuscripts of all or portions of the Hebrew Scriptures extant today in various libraries. The vast majority contain the Masoretic text and are of the tenth century C.E. or thereafter. The Masoretes (of the second half of the first millennium C.E.) sought to transmit the Hebrew text faithfully and made no changes in the wording of the text itself. However, to preserve the traditional pronunciation of the vowelless consonantal text, they devised systems of vowel pointing and accenting. Additionally, in their Masora, or marginal notes, they drew attention to textual peculiarities and gave corrected readings they considered necessary. It is the Masoretic text that appears in printed Hebrew Bibles of the present day.

Damaged Hebrew Scripture manuscripts used in Jewish synagogues were replaced by verified copies, and the defaced or damaged manuscripts were stored in a genizah (a synagogue storeroom or repository). Finally, when it was full, the manuscripts were removed and ceremoniously buried. Doubtless many ancient manuscripts perished in that way. But the contents of the synagogue genizah in Old Cairo were spared, probably because it was walled up and forgotten for centuries. Following the rebuilding of the synagogue in 1890 C.E., the manuscripts in its genizah were reexamined, and from there fairly complete Hebrew Scripture manuscripts and fragments (some said to be of the sixth century C.E.) found their way into various libraries.

One of the oldest extant fragments containing Biblical passages is the Nash Papyrus, found in Egypt and preserved at Cambridge, England. Evidently part of an instructional collection, it is of the second or first century B.C.E. and consists of only four fragments of 24 lines of a pre-Masoretic text of the Ten Commandments and some verses of Deuteronomy, chapters 5 and 6.

Since 1947 many Biblical and non-Biblical scrolls have been found in various areas W of the Dead Sea, and these are referred to generally as the Dead Sea Scrolls. Most significant among them are manuscripts discovered in a number of caves in and about the Wadi Qumran (Nahal Qumeran). These are also known as the Qumran texts and evidently once belonged to a Jewish religious community centered at nearby Khirbet Qumran (Horvat Qumeran). The first discovery was made by a Bedouin in a cave about 15 km (9.5 mi) S of Jericho, where he found a number of earthenware jars containing ancient manuscripts. One of these was the now-renowned Dead Sea Scroll of Isaiah (1QIs⁠^a), a well-preserved leather roll of the entire book of Isaiah, except for a few gaps. (PICTURE, Vol. 1, p. 322) It contains a pre-Masoretic Hebrew script and has been dated toward the end of the second century B.C.E. Hence, it is about a thousand years older than the oldest extant manuscript of the Masoretic text. However, though showing some differences in spelling and grammatical construction, it does not vary doctrinally from the Masoretic text. Among the documents recovered in the Qumran area are fragments of over 170 scrolls representing parts of all Hebrew Scripture books except Esther, and in the case of some books, more than one copy exists. These manuscript scrolls and fragments are believed to range in date from about 250 B.C.E. to about the middle of the first century C.E., and they exhibit more than one type of Hebrew text, such as a proto-Masoretic text or one underlying the Greek Septuagint. Studies of such materials are still in progress.

Among notable vellum Hebrew manuscripts of the Hebrew Scriptures is the Cairo Karaite Codex of the Prophets. It contains the Masora and vocalization, and its colophon indicates that it was completed in about 895 C.E. by the noted Masorete Moses ben Asher of Tiberias. Another significant manuscript (of 916 C.E.) is the Petersburg Codex of the Latter Prophets. The Aleppo Sephardic Codex, once preserved at Aleppo, Syria, and now in Israel, until 1947 contained the entire Hebrew Scriptures. Its original consonantal text was corrected, punctuated, and furnished with the Masora about 930 C.E. by Aaron ben Asher, son of Moses ben Asher. The oldest dated manuscript of the complete Hebrew Scriptures in Hebrew is the Leningrad Manuscript No. B 19⁠^A, preserved in the Public Library in St. Petersburg, Russia. It was copied in 1008 C.E. “from the corrected books prepared and annotated by Aaron ben Moses ben Asher the teacher.” Another noteworthy Hebrew manuscript is a codex of the Pentateuch preserved in the British Library (Codex Oriental 4445), consisting of Genesis 39:20 to Deuteronomy 1:33 (except for Nu 7:46-73 and 9:12–10:18, which are lacking or have been supplied by a later hand) and probably dating from the tenth century C.E.

Many manuscripts of the Hebrew Scripture portion of the Bible were written in Greek. Among those of particular note is one in the collection of the Fouad Papyri (Inventory Number 266, belonging to the Société Egyptienne de Papyrologie, Cairo), containing portions of Genesis and of the second half of Deuteronomy according to the Septuagint. It is of the first century B.C.E. and shows, in various places, the divine name written in square Hebrew characters within the Greek text. Fragments of Deuteronomy, chapters 23 to 28, are found in Rylands Papyrus iii. 458 of the second century B.C.E., preserved in Manchester, England. Another leading manuscript of the Septuagint contains fragments of Jonah, Micah, Habakkuk, Zephaniah, and Zechariah. In this leather scroll, dated to the end of the first century C.E., the divine name is rendered by the Tetragrammaton written in ancient Hebrew characters.​—See NW appendix, pp. 1562-1564.

Hebrew and Christian Greek Scriptures. The most important and most complete extant Bible manuscripts in Greek were written on vellum in uncial letters.

Vatican Manuscript No. 1209. The Vatican Manuscript No. 1209 (Codex Vaticanus), designated internationally by the symbol “B,” is an uncial codex of the fourth century C.E., possibly produced in Alexandria, and it originally contained the entire Bible in Greek. A corrector of later date retraced the letters, perhaps because the original writing had faded, except that he skipped letters and words he considered incorrect. Originally this codex probably had approximately 820 leaves, of which 759 remain. Most of Genesis is gone, as well as a part of Psalms, Hebrews 9:14 to 13:25, and all of First and Second Timothy, Titus, Philemon, and Revelation. Codex Vaticanus is preserved at the Vatican Library in Rome, Italy, and is known to have been there as early as the 15th century. However, Vatican Library authorities made access to the manuscript extremely difficult for scholars and did not publish a full photographic facsimile of the entire codex until 1889-1890.

Sinaitic Manuscript. The Sinaitic Manuscript (Codex Sinaiticus) is also of the fourth century C.E., but Codex Vaticanus may be a little older. The Sinaitic Manuscript is designated by the symbol א (ʼaʹleph, first letter in the Hebrew alphabet), and while it evidently once contained the entire Bible in Greek, part of the Hebrew Scriptures has been lost. However, it has all the Christian Greek Scriptures. Likely this codex originally consisted of 730 leaves, at least, though the whole or parts of just 393 are now verified to be extant. It was discovered (one portion in 1844 and another in 1859) by the Bible scholar Konstantin von Tischendorf at the Monastery of St. Catherine at Mount Sinai. Forty-three leaves of this codex are kept in Leipzig, portions of three leaves are at St. Petersburg, Russia, and 347 leaves are preserved at the British Library in London. It has been reported that 8 to 14 more leaves were discovered in the same monastery in 1975.

Alexandrine Manuscript. The Alexandrine Manuscript (Codex Alexandrinus), designated by the letter “A,” is a Greek uncial manuscript containing most of the Bible, including the book of Revelation. Of possibly 820 original leaves, 773 have been preserved. This codex is generally considered to be of the first half of the fifth century C.E., and it is also preserved in the British Library.​—PICTURE, Vol. 2, p. 336.

Codex Ephraemi Syri rescriptus. The Codex Ephraemi Syri rescriptus (Codex Ephraemi), designated internationally by the letter “C,” is also generally considered to have originated in the fifth century C.E. It is written in Greek uncials on vellum and is a rewritten codex, a palimpsest manuscript. The original Greek text was removed, and a number of leaves were then written over with discourses of Ephraem Syrus (the Syrian), rendered in Greek. This was done probably during the 12th century, when there was a scarcity of vellum. However, the underlying text has been deciphered. While “C” evidently once contained all the Scriptures in Greek, just 209 leaves remain, 145 being of the Christian Greek Scriptures. Hence, this codex now contains only portions of Hebrew Scripture books and parts of all books of the Christian Greek Scriptures except Second Thessalonians and Second John. It is preserved at the Bibliothèque Nationale in Paris.
