What Scripture says
Scripture claims God’s word endures: “The grass withers, the flower fades, but the word of our God will stand forever” (Isaiah 40:8, ESV). Jesus said not “an iota, not a dot” of the law would pass away (Matthew 5:18). Paul says the Jews “were entrusted with the oracles of God” (Romans 3:2), which included the task of preserving them.
The Dead Sea Scrolls let us test how well that word was actually preserved by copyists over a thousand years.
What the evidence says
Archaeology
The discovery
In late 1946 or early 1947, a young Bedouin shepherd searching for a lost goat threw a stone into a cave near Qumran, by the Dead Sea, and heard pottery break. Inside were jars holding ancient scrolls. Over the next decade, archaeologists and Bedouin found scrolls and fragments in 11 caves.
In all, about 900–1,000 manuscripts were found, most in fragments, dating roughly from the 3rd century BC to the 1st century AD. Their dates come from handwriting styles, radiocarbon tests and coins found at the site.
What was found
- Biblical manuscripts, about a quarter of the total. Every book of the Hebrew Bible except Esther is represented, at least in fragments. The most copied were Psalms (around 36 copies), Deuteronomy (about 30) and Isaiah (about 21).
- Other Jewish writings, such as 1 Enoch, Jubilees and Tobit (see 3B).
- The community’s own writings, such as the Community Rule, the War Scroll and commentaries on the prophets. Many scholars link them with the Essenes, a Jewish group described by Josephus, though this is debated.
Textual Criticism
The Great Isaiah Scroll
Before the discovery, the oldest complete Hebrew Old Testament manuscripts dated from around AD 1000: the Aleppo Codex (c. 930) and the Leningrad Codex (1008), both produced by the Masoretes, medieval Jewish scribes.
The Great Isaiah Scroll from Cave 1 (called 1QIsa-a), a complete copy of all 66 chapters, dates to around 125 BC, about 1,000 years older.
When scholars compared them, the text matched closely:
- Most differences are spelling (the scroll often adds vowel letters), small grammatical changes or copying slips.
- A few are more significant. In Isaiah 53:11, the scroll reads “he shall see light”, as does the Greek Septuagint, where the medieval text has “he shall see”. Most modern Bibles, including the ESV, follow the scroll here.
- The substance of Isaiah, including chapter 53, is the same.
A second Isaiah scroll from the same cave (1QIsa-b) is even closer to the medieval text.
More than one text type
The scrolls also showed that a few books circulated in more than one version at the time:
- Jeremiah existed in a shorter form, about one-eighth shorter, matching the Septuagint, alongside the longer form found in the medieval Hebrew text.
- Deuteronomy 32:8 reads “sons of God” in a Qumran copy (4QDeut-j), where the medieval Hebrew text has “sons of Israel”. Several modern Bibles, including the ESV, follow the scroll.
So the text’s history was a little more complex than once thought. But the core text was stable, and scholars can now see the variant forms side by side.
| Manuscript | Date | What it showed |
|---|---|---|
| Great Isaiah Scroll | c. 125 BC | Isaiah nearly identical to medieval copies |
| Aleppo Codex | c. AD 930 | The medieval standard text |
| 4QJer-b | 2nd century BC | A shorter Jeremiah, like the Septuagint |
A caution about forgeries
Since 2002, some “new” Dead Sea Scroll fragments sold on the antiquities market have proved to be modern forgeries. In 2020, the Museum of the Bible announced that all 16 of its fragments were fakes. These forgeries don’t affect the authentic scrolls found by archaeologists, but they show why provenance matters.
Where they meet
The Scrolls confirmed that Jewish scribes copied Scripture with remarkable care over a thousand years. The Old Testament we have today closely matches what Jews read in Jesus’ day, and where small differences exist, modern translations take the scrolls into account.
What’s still open
- How to weigh the different versions of some books, such as Jeremiah.
- Who exactly lived at Qumran and wrote the community’s own texts.
Bottom line
The Dead Sea Scrolls’ Isaiah scroll is about 1,000 years older than the previous oldest copy and matches it closely. The evidence is direct and widely accepted, so this is rated Settled.
