En-Gedi Scroll in the context of "Torah ark"

The Masoretic Text (MT or 𝕸; Hebrew: נֻסָּח הַמָּסוֹרָה, romanized: Nussāḥ ham-Māsorā, lit. 'Text of the Tradition') is the authoritative Hebrew and Aramaic text of the 24 books of the Hebrew Bible (Tanakh) in Rabbinic Judaism. The Masoretic Text defines the Jewish canon and its precise letter-text, with its vocalization and accentuation known as the masora. Referring to the Masoretic Text, masora specifically means the diacritic markings of the text of the Jewish scriptures and the concise marginal notes in manuscripts (and later printings) of the Tanakh which note textual details, usually about the precise spelling of words. It was primarily copied, edited, and distributed by a group of Jews known as the Masoretes between the 7th and 10th centuries of the Common Era (CE). The oldest known complete copy, the Leningrad Codex, dates to 1009 CE and is recognized as the most complete source of biblical books in the Ben Asher tradition. It has served as the base text for critical editions such as Biblia Hebraica Stuttgartensia and Adi.

The differences attested to in the Dead Sea Scrolls indicate that multiple versions of the Hebrew scriptures already existed by the end of the Second Temple period. Which is closest to a theoretical Urtext is disputed, as is whether such a singular text ever existed. The Dead Sea Scrolls, dating to as early as the 3rd century BCE, contain versions of the text which have some differences with today's Hebrew Bible. The Septuagint (a compilation of Koine Greek translations made in the third and second centuries BCE) and the Peshitta (a Syriac translation made in the second century CE) occasionally present notable differences from the Masoretic Text, as does the Samaritan Pentateuch, the text of the Torah preserved by the Samaritans in Samaritan Hebrew. Fragments of an ancient 2nd–3rd-century manuscript of the Book of Leviticus found near an ancient synagogue's Torah ark in Ein Gedi have identical wording to the Masoretic Text.

Virtual unfolding, also known as virtual unrolling, virtual unwrapping, or virtual unravelling, is a non-destructive method of unrolling and reading damaged or fragile scrolls. Unlike physical unrolling (which often destroys such scrolls), virtual unrolling starts with a 3D X-ray scan in a tomograph, which is later programmatically unrolled. The unrolled image then can be studied in detail and processed using machine learning methods. Virtual unfolding was used for the burned En-Gedi Scroll from Israel, for water-damaged Bressingham and burned Diss Heywood scrolls from England, for the Herculaneum papyri burned during the Pompeii volcano eruption, for a Mongolian Buddhist scroll, found inside a statue, for a metal scroll amulet from Jordan, unopened letters from Europe, and for bamboo scrolls from China.
