The Isaiah Scroll from Cave 1

When

The Isaiah Scroll from Cave 1, catalogued as 1QIsaa, takes its place in the long history of Hebrew Bible manuscripts as the largest and best preserved of the seven original Dead Sea Scrolls unearthed in the spring of 1947. The dating of the scroll itself has been a matter of careful palaeographic argument ever since its discovery. On the basis of the formal Jewish book hand in which it is written, with its tall, narrow letter forms and distinctive spacing conventions, scholars have placed its copying in the second century before the common era, broadly between 150 and 100 BCE, with most specialists preferring a window around 125 BCE. This places the manuscript in the late Second Temple period, after the Ptolemaic and Seleucid imperial administrations had given way to Hasmonean rule in Judea but well before the destruction of the Jerusalem temple by Rome.

The dating matters because the scroll offers the oldest complete witness to the Book of Isaiah, predating by more than a thousand years the medieval Masoretic codices that had previously been the earliest near-complete copies available. The Aleppo Codex, written in the early tenth century CE, and the Leningrad Codex, copied in 1008 CE and now held in the Russian National Library, became the textual base for modern printed Hebrew Bibles, including the third edition of Biblia Hebraica Stuttgartensia. The Isaiah Scroll is not a direct ancestor of these Masoretic manuscripts; rather, it preserves an older stratum of the text, closer in time to the composition of the book’s final form, and it shows features that link it to the family of texts that scholars now call the proto-Masoretic tradition.

The discovery itself has its own chronology. Between November 1946 and February 1947 a Bedouin shepherd named Muhammad edh-Dhib, searching for a stray goat along the marl cliffs that border the northwest shore of the Dead Sea, threw a stone into a cave mouth in the limestone and heard pottery shatter. He and his cousins returned over the following weeks and removed seven scrolls from the cave, eventually selling them through a chain of antiquities dealers in Bethlehem and Jerusalem. By the end of 1947 the four most complete scrolls had reached the American Schools of Oriental Research in Jerusalem and were being studied by John Trever, William Brownlee, and Frank Moore Cross. The three other scrolls, including the Community Rule, were obtained by Marfin (Metropolitan) Samuel and held in the Syrian Orthodox monastery of Saint Mark in Jerusalem until 1954, when they were transferred to a special wing of the Shrine of the Book in what was then the new Israel Museum complex.

Within five years of the discovery, the original seven scrolls had been acquired by the newly established State of Israel. Yigael Yadin, son of the archaeologist Eleazar Sukenik who had already secured three of the scrolls in late 1947, used a donation from a New York benefactor to bring the remaining four from the United States, where they had been exhibited at the Azusa Street revival meeting hall in Los Angeles in 1949 and 1950 before being placed in the Wallach Brothers’ vault at the Hebrew Union College in Cincinnati. The Isaiah Scroll’s journey from the cave to the Shrine of the Book was therefore unusually public, and its arrival in Israel in 1954 marked the formal beginning of the modern scholarly study of the Dead Sea Scrolls as a coherent library rather than as isolated antiquities.

For half a century afterwards, access to the scroll was tightly controlled. A small circle of scholars received photographs and later plates, and publication proceeded in the series Discoveries in the Judaean Desert. It was not until the early 1990s that the Israel Antiquities Authority began to release photographs more freely, and not until 2016 that the Shrine of the Book put high-resolution colour images of the entire scroll online through the Leon Levy Dead Sea Scrolls Digital Library. The digital release transformed the pace and reach of Isaiah Scroll scholarship, opening the manuscript to a generation of digital-philological work that had previously been the privilege of a handful of editors.

The early wave of publication in the 1950s produced the first authoritative text of the scroll. The American editor Millar Burrows, working from the photographs and a direct examination of the manuscript in 1952 and 1953, published two volumes of preliminary text in 1950 and 1951, with corrections and additions following in 1957. The standard critical text, long the workhorse of Qumran Isaiah studies, was issued in the Discoveries in the Judaean Desert series in 1959. A new diplomatic edition by Eugene Ulrich and Peter Flint, based on the high-resolution digital photographs, was published in 2010 and remains the standard scholarly reference. Subsequent work has refined the readings and added the contested or marginal readings that the earlier editors had hesitated to include in the main text.

Where

The scroll was found in Cave 1 at Wadi Qumran, the same cave on the marl terrace that had been excavated by Roland de Vaux and Gerald Lankard Harding in February 1949 and February 1950, after the original Bedouin discovery had been disclosed to the French Dominican archaeologist. The cave sits at the foot of the northwest cliffs of the Dead Sea, some two kilometres south of the ruin now identified with the sectarian settlement at Khirbet Qumran, and roughly thirteen kilometres south of Jericho. The site lies in the Jordan Rift Valley, below mean sea level, in an arid zone where the annual rainfall is less than one hundred millimetres and the summer humidity falls dramatically. These climatic conditions are the immediate reason the scroll survived: the parchment was kept dry, the ink remained stable, and the cave acted as a natural climate-controlled archive.

The cave itself is a natural solution cavern in the limestone, with a single low entrance opening onto a ledge some twenty metres above the valley floor. Inside, the chamber widens into a roughly oval space about ten metres by six. The ceiling is low, generally less than two metres in the accessible portions. The floor is littered with collapsed stones, animal bones from hyena occupation in later centuries, and a thick dusty sediment that was removed by de Vaux’s team. The original Bedouin discovery concentrated on a small inner chamber or shelf at the back of the cave, where seven jars, two of them still sealed, contained the scrolls together with a few linen wrappers and some fragments of leather and papyrus.

The jars were cylindrical, of the type known from the late Hellenistic and early Roman periods in Judea. They are similar to those found in the cemetery at Qumran and to those recovered from other caves in the surrounding cliffs, particularly Caves 4, 7, 8, 9 and 10. The scroll of Isaiah was recovered not in a jar but loosely, in a state of partial breakage, having been removed from its container before the Bedouin brought it out. Its initial condition was already fragmentary, with several large pieces missing along the right-hand margin and at the central joins of the seventeen sheets of parchment from which it is made.

The geographic setting shaped the manuscript’s preservation in two further ways. The cliffs of Wadi Qumran face away from the prevailing northwesterly winds and from direct sunlight for much of the day, so the cave temperature remained close to a stable year-round mean of around twenty degrees Celsius with low diurnal variation. The second is the mineralogy of the surrounding marl. The wadi drains runoff from the Pleistocene lacustrine deposits that line the rift valley, and the salts carried into the cave by occasional damp air contribute to the deposition of salt crystals on the surface of the parchment that have been a continuous conservation challenge.

The geopolitical setting of the cave, on the western edge of what was the Emirate of Transjordan under British Mandate and what became the Hashemite Kingdom of Jordan after 1946, created the legal and political framework that has governed access to the scrolls for the better part of seventy-five years. The 1948 Arab-Israeli War and the 1967 Six Day War redrew the map twice, and the question of who held the scrolls and where they were studied moved with the lines of ceasefire. From 1949 to 1967 the scrolls were in territory controlled by Jordan, with excavation permits issued by the Department of Antiquities in Amman. From 1967 onwards they came under Israeli administration, and the Israel Antiquities Authority was established in 1989 to manage and publish them. The question of Jordanian claims to certain scrolls, particularly to the Copper Scroll which has been on display at the Jordan Museum in Amman since 2014, has never been fully settled diplomatically.

From an archaeological perspective the cave sits within a small but dense cluster of cave sites that together form the Qumran library. Eleven caves in the immediate area, numbered 1 to 11 in order of discovery, have yielded Hebrew, Aramaic, and Greek manuscripts. The Cave 1 context, however, differs from Cave 4 in one important respect: Cave 1 is the only cave from which seven complete or nearly complete scrolls were recovered in their original archaeological context; Cave 4 produced more than fifteen thousand fragments, the great majority of which are scraps too small to read without a microscope. The Isaiah Scroll is therefore the flagship of the Cave 1 material and remains the most legible single manuscript of the entire library.

What

The Isaiah Scroll is a single parchment roll, written on the skin of an animal whose identification has been settled as domestic goat on the basis of hair analysis carried out in the 1950s. The parchment is unusually well prepared: thin, even, and finely scraped, with a smooth surface that takes ink cleanly. The scroll is roughly 734 centimetres long when fully assembled, with seventeen sheets stitched end to end into a single continuous roll. The height of the writing area is approximately 26.5 centimetres. The columns are uniform, generally between 11 and 13 lines of text, with occasional narrower or wider columns where the scribe accommodated the sense divisions of the Hebrew.

Column ruling is lightly incised on the flesh side of the parchment, and the scribe maintained a strict left margin by eye. The Hebrew script of the scroll is a formal book hand of the late Hasmonean period, sometimes called the Hasmonean semi-cursive, with strong affinity to the formal hands attested on Jewish coinage of the period. Letters are tall and narrow, the aleph and lamedh lean slightly to the right, and the final forms of mem, nun, pe and tsade are used consistently. There is little or no influence from the more cursive Aramaic chancery hands that were becoming common in the eastern Diaspora at the same date, and the absence of that influence is itself a useful diagnostic for dating and localisation.

The text covers all sixty-six chapters of the Masoretic Book of Isaiah, beginning in chapter 1 with the words חֶזְיוֹן יְשַׁעְיָהוּ בֶן־אָמוֹץ (“The vision of Isaiah son of Amoz”) and ending at the close of chapter 66 with כִּי כַאֲשֶׁר יִבְעַל הָאָרֶשׂ מֵעָלַי תְּפִלָּתִי. It is the only complete pre-medieval Hebrew manuscript of Isaiah to have survived, although parts of the book are preserved in the slightly earlier fragments from Murabba’at and Nahal Hever, and the Ben Asher tradition in the Tiberian line that led to the Aleppo and Leningrad codices is the direct medieval continuation of the textual tradition this scroll represents.

The orthography of the scroll is consistent with that of the late Second Temple period. It uses the full plene spelling preferred by scribes in Judea before the Masoretes standardised the defective spelling that became canonical in the Middle Ages. There are several instances of scriptio plena for the long vowels where the Masoretic text reads scriptio defectiva, and conversely a small number of cases where the scroll has the defective form where the Masoretic text has the plene. The frequency and distribution of these differences has been the subject of a long and still-active debate about whether the scroll was copied from a written exemplar in the plene tradition and then revised in places by a scribe who knew the defective form, or whether it represents a transitional state in which neither spelling had yet been canonically fixed.

More than 1,600 textual variants from the Masoretic text have been catalogued in scholarly editions of the scroll. The great majority are minor: differences in spelling, in the division of words, in the use of the conjunction, in the presence or absence of the article, and in the resolution of morphologically ambiguous forms. A small number are more consequential. The scroll sometimes preserves a shorter reading of a verse than the Masoretic tradition; in a handful of cases it preserves a longer one; in a few notable passages the wording diverges in ways that approach the Septuagint Greek translation of Isaiah, the oldest translation of the book, which had been made in the third or second century BCE in Ptolemaic Alexandria.

One of the most discussed variants occurs at Isaiah 53:11, where the Masoretic text reads מֵעֲמַל נַפְשׁוֹ יִרְאֶה יִשְׂבָּע (“from the travail of his soul he shall see, he shall be satisfied”), and the scroll reads the verb in the singular rather than the plural. The difference is small in itself, but it has generated a body of secondary commentary disproportionate to its weight because it touches on questions about the suffering servant figure that have been central to Jewish-Christian disputation for two millennia. The scroll’s reading here does not, in fact, alter the sense of the passage in any decisive way, and the broader argument over the servant songs of Isaiah has been theologically as much as textually driven.

Quotation marks, vocalisation, and cantillation are absent, as they would be in any pre-Masoretic manuscript. The scroll contains no glosses, no margin notes, and no commentary in the way that the Habakkuk Pesher from the same cave does. It is in this respect a pure biblical manuscript, copied as scripture and not as a proof-text for sectarian interpretation. Some scholars have argued that the absence of glossing should warn against assuming the scroll belonged to the Essene community at Qumran that left the pesharim; the manuscript may have been deposited by refugees from the Roman campaigns of the late First Jewish Revolt, a generation or more after the scroll was copied.

The parchment itself is in remarkably good condition for its age. The leather is supple where it has been kept in stable humidity, brittle where it has been exposed to desiccation cycles. Several joins between the sheets are intact, and the stitching, which uses twisted sinew thread, has held in a number of places where one might have expected it to fail. Damage is concentrated along the upper and lower edges of the scroll, where rodents and abrasion have removed small amounts of text. The most significant loss is in the central section of the scroll, where Isaiah chapters 36 to 46 fall, and where the sheets have been broken or torn along the joins; these passages had to be reconstructed from other Dead Sea fragments, particularly 1QIsab and the great Cave 4 collection, before a continuous text could be established.

There is evidence that the scroll has been corrected in places by later hands. A second scribe, working in a slightly different book hand, has overwritten certain letters in a darker ink that is visible against the original. The corrections are not consistent in style, and some of them are demonstrably wrong, restoring readings that the original scribe had deliberately altered. The correction hands belong, on palaeographic grounds, to the late first century BCE and to the early first century CE, and they reflect the continuing use of the manuscript in a community that read and re-read it and was unwilling to copy a fresh scroll when corrections would suffice. This reuse, after a hundred years or more, suggests that the scroll was treated as a valuable copy that circulated within a library rather than as a one-off commission for a single patron.

The scribe responsible for the main body of the scroll wrote with a fine reed pen held at a consistent angle to the parchment. Ink was mixed from carbon black and a binder, possibly gum arabic or a similar vegetal gum, in proportions that produced the deep black-brown colour characteristic of the manuscript. The scribe worked from right to left, in horizontal lines, in columns narrow enough to be read without unrolling the parchment more than a handspan at a time. The joining of sheets was done with sinew thread in a chain stitch at the back of the roll, and the final sheet was given a wooden roller of the kind used for Torah scrolls. None of the wooden parts has survived, but the traces of the stitching and the characteristic wear patterns at the beginning and end of the roll allow the original form to be reconstructed.

Why it matters

The Isaiah Scroll matters to the textual criticism of the Hebrew Bible for three converging reasons. First, it confirms the antiquity and stability of the consonantal text of Isaiah. Although the variants from the Masoretic tradition are numerous, the bulk of them are orthographic rather than substantive, and the agreement between the scroll and the medieval codices is sufficiently close to confirm that the text we now read in printed Hebrew Bibles had reached a recognisable form by the late Second Temple period. The longer history of the textual transmission of Isaiah, from the time of its composition in the late eighth or early seventh century BCE through the Babylonian exile and into the Persian and Hellenistic periods, had previously been a matter of inference; the Isaiah Scroll is the earliest full stop on that inferred line.

Second, the scroll forces a reconsideration of the place of the Septuagint in the textual history. The Septuagint translation of Isaiah was made in Alexandria in the third or early second century BCE and reflects a Hebrew text that differed in places from the consonantal base of the Masoretic tradition. The presence of those same agreements with the Septuagint in the Isaiah Scroll, in passages where the Masoretic text disagrees with both, demonstrates that the Septuagint translator was translating a Hebrew text substantially similar to the scroll. The long-running question of whether the Septuagint represents an independent recension, or whether it was translated from a text close to what the Masoretes would later fix, is now settled in favour of the latter; the Septuagint translator was working from a Hebrew ancestor of the Masoretic tradition, with only a small number of passages where a non-Masoretic Hebrew form lies behind his translation.

Third, the scroll sharpens the question of what the proto-Masoretic text was. The term is a scholarly construct for the consonantal text that lies behind the medieval Masoretic codices, with their vocalisation, cantillation, and Masorah Magna and Parva apparatus. The Isaiah Scroll shows that this proto-text existed by the second century BCE in essentially the form in which it would be preserved for a thousand years. There are differences, but they are not of the order of magnitude that one finds between, for example, the Septuagint’s Vorlage and the Masoretic text. The Isaiah Scroll is therefore a primary witness to the proto-Masoretic tradition and a benchmark against which other second-period Hebrew manuscripts must be measured.

Beyond the technical questions of textual criticism, the scroll matters to the history of Jewish scribal practice. The writing is the work of a trained, careful, and evidently experienced scribe, working to a clear set of conventions about line length, column ruling, margin, and orthography. The Hebrew book hand of the scroll is a relatively rare survival, and the small number of complete manuscripts in this script from the late Hasmonean period gives it a disproportionate weight as evidence for the everyday work of professional scribes in Judea before the destruction of the temple. The scroll also offers evidence for the way in which biblical books were physically produced: as single rolls, with each sheet prepared and stitched end to end, in the manner of a Torah scroll but on a much larger scale than would be necessary for the Pentateuch alone.

The scroll matters to the history of interpretation as well. The Christian tradition has often used Isaiah, and especially the servant songs of Isaiah 40 to 55, as proof-text for the life and death of Jesus of Nazareth. The text-critical work on the scroll has shown that the Christian arguments built on small variants between the Masoretic text and the Septuagint, particularly on the third servant song in Isaiah 52 and 53, are not supported by the Hebrew evidence. The Hebrew of the scroll, agreeing as it does with the Masoretic text in those passages, suggests that the Christian exegetical reading relied on a translation tradition whose differences from the Hebrew are translation choices rather than evidence for a divergent Hebrew Vorlage. This has had the effect of narrowing the textual ground on which Christian readings of Isaiah can rest and widening the ground on which Jewish and modern critical readings can meet.

Finally, the Isaiah Scroll matters to the institutional history of modern biblical scholarship. The first generation of work on the scroll, in the early 1950s, coincided with the establishment of the State of Israel, with the political geography of the Palestine Mandate, and with the founding of the new American schools of biblical archaeology and of the École Biblique in Jerusalem. The very name Dead Sea Scrolls was a brand before it was a category, and the Isaiah Scroll was the most famous exhibit in the brand. The scholarly and public attention the scroll attracted in the 1950s and 1960s was the precondition for the funding of the larger excavation campaigns of the 1950s and the eventual recovery of the more than nine hundred additional fragments from Caves 4 to 11. Without the public attention that the Isaiah Scroll commanded in 1948 and 1949, the Cave 4 collection might not have been sought, and the modern study of the Hebrew Bible would be poorer by several thousand manuscripts.

The continuing importance of the scroll to textual scholarship in the twenty-first century can be measured by the pace of recent publication. The digital release of the high-resolution photographs of the manuscript through the Leon Levy Library in 2016 enabled a wave of new work that has been particularly active in the digital-philological application of multispectral imaging, in the statistical analysis of orthographic variation, and in the use of machine learning to identify and group the hands responsible for individual sheets of the scroll. These are techniques that the original editors in the 1950s could hardly have imagined, but the scroll itself remains the same parchment, with the same ink, in the same cave, and the underlying evidence it provides is unchanged.

Authorship, transmission, and the wider library

The Book of Isaiah in its Masoretic form is the longest of the prophetic books and the most internally complex. Modern critical scholarship has long held that the book is a composite of writings from at least three distinct periods: the eighth-century Isaiah of Jerusalem, whose oracles against Judah and the surrounding nations form the bulk of chapters 1 to 39; an anonymous prophet of the Babylonian exile, whose words of comfort to the exiles form chapters 40 to 55; and a third, later prophet, active in the early Persian period, whose oracles on the restoration of Jerusalem and the new creation form chapters 56 to 66. The Isaiah Scroll treats the three sections as a single, continuous book, in the same order and with the same divisions as the Masoretic tradition. This is significant because it shows that the unified status of Isaiah as a single corpus, with three parts but one authorial signature, was established in the late Second Temple period. The scroll is therefore not only the oldest full witness to the text but also the oldest witness to the canonical shape of the book.

The transmission of Isaiah from the late Second Temple period to the Masoretic codices of the early Middle Ages is mediated by a chain of manuscripts whose exact content we will never know. The Isaiah Scroll gives us one point on that chain. Other points are visible in the fragments from Murabba’at, in the Greek Minor Prophets Scroll from Nahal Hever, and above all in the great Cave 4 collection, which contains a dozen manuscripts of Isaiah in whole or in part, ranging in date from the late first century BCE to the early first century CE. The picture is one of remarkable uniformity: the consonantal text of Isaiah was reproduced with care, with only small adjustments in orthography and a small number of substantive changes that are best explained as the natural drift of a copied text rather than as deliberate editing.

The Cave 1 library of which the Isaiah Scroll was a part is much larger than the seven scrolls first recovered by the Bedouin. Subsequent excavations by de Vaux’s team in 1949 and 1950 found additional fragments in the same cave, including the Hebrew fragments of the Apocryphon of Moses, the fragmentary Vision of Shem, and a small leather amulet with the Priestly Blessing. The Cave 1 collection as a whole is therefore a small library of perhaps a dozen discrete works in Hebrew and Aramaic, plus a handful of Greek fragments, that had been carefully wrapped and placed in jars at the back of the cave at some point in the middle of the first century CE. The jars themselves are of a type that came into common use in Judea only in the late first century BCE, and the contents, judging from the manuscripts preserved, are a deliberate selection of religious literature that reflects the tastes of a specific community.

The community most often associated with the Qumran library is the Essene sect described by Pliny the Elder, Josephus, and Philo. The sectarian texts from Cave 1, in particular the Community Rule and the Habakkuk Pesher, contain language and ideas consistent with the small Essene movement that Josephus describes as living in monastic-style communities in the Judean desert. The Isaiah Scroll, however, is not a sectarian text; it is biblical scripture. Its presence in the cave alongside the sectarian texts suggests that the community valued the scroll as scripture, not as evidence for their particular interpretation. The sectarian community treated the scroll as authoritative Hebrew Bible, in the way that medieval Christian monks treated the Vulgate: as the canonical text whose meaning was to be interpreted, not altered.

The presence of a complete Isaiah scroll in the cave is therefore evidence for the way in which late Second Temple communities in Judea treated the prophetic literature. The prophet Isaiah, who had predicted the restoration of Israel and the gathering of the exiles, would have been of particular interest to a community in the late first century BCE waiting for the end of the present age. The community read the prophet in the light of their own historical situation and produced the Habakkuk Pesher as an example of how such reading should be done. The Isaiah Scroll was the scriptural source on which that pesher-like reading depended, and its preservation in the cave shows the practical centrality of biblical text to the sectarian enterprise.

The history of the Masoretic text after the destruction of the temple in 70 CE is in many ways a continuation of the scribal practice visible in the Isaiah Scroll. The Tiberian Masoretes of the seventh to tenth centuries CE, including the famous families of ben Asher and ben Naphtali, took the consonantal text of the Second Temple period and added the vowel points, the cantillation marks, and the elaborate Masorah Magna and Parva that make their codices the canonical form of the Hebrew Bible. The Isaiah Scroll is the earliest and best-preserved window into that consonantal text before the Masoretes fixed it in their codices, and it is the indispensable evidence for the relationship between the pre-Masoretic and the post-Masoretic forms of the Hebrew Bible.
