NASV Hebrews 9:25. "...the high priest enters the Holy Place year by year with blood not his own."
NIV Hebrews 9:25. "...the high priest enters the Most Holy Place every year with blood that is not his own."
The NIV supplies "understood" information about the Day of Atonement, namely that the high priest's duties took place in the compartment of the temple known specifically as the Most Holy Place. Note that the NASV simply says "holy place" reflecting the more literal translation of "hagios."
The Integrity of the Manuscript Evidence
As with any ancient book transmitted through a number of handwritten manuscripts, the question naturally arises as to how confident can we be that we have anything resembling the autograph. Let us now look at what evidences we have for the integrity of the New Testament manuscripts. Let us look at the number of manuscripts and how close they date to the autographs of the Bible as compared with other ancient writings of similar age.
Tacitus, the Roman historian, wrote his Annals of Imperial Rome in about A.D. 116. Only one manuscript of his work remains. It was copied about 850 A.D.
Josephus, a Jewish historian, wrote The Jewish War shortly after 70 A.D. There are nine manuscripts in Greek which date from 1000-1200 A.D. and one Latin translation from around 400 A.D.
Homer's Iliad was written around 800 B.C. It was as important to ancient Greeks as the Bible was to the Hebrews. There are over 650 manuscripts remaining but they date from 200 to 300 A.D. which is over a thousand years after the Iliad was written.
The Old Testament autographs were written 1450 - 400 B. C.
The Dead Sea Scrolls date between 200 B.C. to 70 A. D and date within 300 years from when the last book of the Old Testament was written.
Two almost complete Greek LXX translations of the Old Testament date about 350 A. D.
The oldest complete Hebrew Old Testament dates about 950 A. D.
Genesis-Deuteronomy were written over 1200 years before the Dead Sea Scrolls.
Codex Vaticanus is an almost complete Greek translation of the Old Testament dating around 350 A.D. The Aleppo Codex is the oldest complete Old Testament manuscript in Hebrew and was copied around 950 A.D. The Dead Sea Scrolls date from within 200-300 years from the last book of the Old Testament. However since the five books of Moses were written about 1450- 1400 B.C. the Dead Sea Scrolls still come almost 1200 years after the first books of the Old Testament were written.
The New Testament autographs were written between 45-95 A. D.
There are 5,664 Greek manuscripts some dating as early as 125 A. D. and an complete New Testament that dates from 350 A. D.
8,000 to 10,000 Latin Vulgate manuscripts.
8,000 manuscripts in Ethiopic, Coptic, Slavic, Syriac, and Armenian.
In addition, the complete New Testament could be reproduced from the quotes that were made from it by the early church fathers in their letters and sermons.
