Dead Sea Scrolls
Scriptural preservation and accuracy
Every Word of Eloah is tried; He is a shield to those taking refuge in Him. Do not add to His Words, Lest He reprove you, and you be found a liar.
Many thousands of written fragments have been discovered in the Dead Sea area. They represent the remnants of larger manuscripts damaged by natural causes or through human interference, with the vast majority only holding small scraps of text. However, a small number of well-preserved, almost intact manuscripts have survived... The texts have great historical, religious, and linguistic significance because they include the second-oldest known surviving manuscripts of works later included in the Hebrew Bible canon, along with deuterocanonical and extra-biblical manuscripts which preserve evidence of the diversity of religious thought in late Second Temple Judaism.
The Dead Sea Scrolls are generally dated from around 200 B.C. to A.D. 68. This is more than 1,000 years older than any manuscripts of the Hebrew Old Testament that we had before their discovery. Because of their age and close similarity with the Masoretic Text, we now have an objective basis for determining that the biblical text used in our modern copies of the Old Testament is accurate.
"As for Me, this is My covenant with them," said YHWH: "My Spirit that is upon you, and My Words that I have put in your mouth, shall not be withdrawn from your mouth, nor from the mouth of your descendants, nor from the mouth of your descendants' descendants," said YHWH, "from this time and forever."
The Isaiah Scroll ... is one of the seven Dead Sea Scrolls that were first recovered by Bedouin shepherds in 1947. The scroll is written in Hebrew and contains the entire Book of Isaiah from beginning to end, apart from a few small damaged portions. It is the oldest complete copy of the Book of Isaiah known, being 1100 years older than the Leningrad Codex, and the most complete scroll out of the 220 found at Qumran. Pieces of the Isaiah Scroll have been carbon-14 dated at least four times, giving calibrated date ranges between 356-103 BC.
The Great Psalms Scroll ... is the most substantial and well preserved Dead Sea Scrolls Psalms manuscript of the thirty-seven discovered in the Qumran caves... The primary body of the manuscript consists of "5 sheets of leather, still sewn together", and is 4.253 meters in length.
