"The Dead Sea Scrolls confirm the Old Testament has been transmitted unchanged."
They confirm the OT has been transmitted carefully — not unchanged.
Evidence card
The rating is tied to the stated evidence, the stated caveat, and the named source trail below.
What's actually true
The Great Isaiah Scroll (1QIsa-a) is, on the whole, remarkably close to the Masoretic text 1,000 years later. For most of the OT, the scrolls confirm scribal continuity.
What gets left out
There are real differences. 4QSam-a often agrees with the LXX against the Masoretic. 4QDeut-q reads 'sons of God' against the Masoretic 'sons of Israel' at Deut 32:8. 11QPs-a contains psalms not in the Masoretic Psalter. The scrolls show the Hebrew Bible was not yet uniform in the Second Temple period. The careful transmission is real; the 'unchanged' claim is a simplification.
