Okay I admire your persistence, Show me what you got. Show me how and who added what to the Bible and why.
As previously mentioned,
The Greek OT the LXX has its origin hundreds years before the birth of Christ. The Greek OT was necessary because of the sins of Israel and the abandonment of "Biblical/Paleo Hebrew" due the Israel being scattered throughout the world. Jews translated the Torah and eventually the entire OT into Greek. These derivative works are the oldest and most accurate sources relative the OT that survive today (extant). The Greek OT is what "drove" the explosion of Christianity throughout the known world. The "layman" could read the "Scriptures" in the Greek language and learn of God. The Greek OT is what those at "Berea" "searched".
Act 17:11 These were more noble than those in Thessalonica, in that they received the word with all readiness of mind, and searched the scriptures daily, whether those things were so.
Act 17:12 Therefore many of them believed; also of honourable women which were Greeks, and of men, not a few.
Notice the appeal to Greeks......
We have the Greek NT because of the Greek OT. The overwhelming majority of quotes in the NT come from the Greek OT.
Men did not have to learn paleo Hebrew to know the Scriptures. The apostles used the LXX. The LXX was the standard for Scriptures for both Jew and Greeks until Jerome sought to create a new Latin translation (there were already what is now considered "Old Latin" manuscripts available. Jerome believed that the few manuscripts he had in Hebrew "honored" Christ more than the LXX. (Just an excuse. Not a reason.) In fact, contrary to popular belief. Jerome never completed the Yulgate. He couldn't. He didn't have and could not find manuscripts/scrolls in Hebrew for much of Proverbs and Psalms. He eventually and another. used the LXX as the source to "fill in the gaps". There is NO copy of the original work of the Vulgate. Zero. In fact, some question if there ever really was a completed copy. The Vulgate wasn't standardized (Latin manuscripts vary up until the 10th century as well.
Now to Hebrew sources. There is no meaningful evidence of the complete Hebrew OT before the 10th century in the MT (Masoretic Text). The DSS (Dead Sea Scrolls) only contain a fragmented assortment of text that vary greatly between LXX sources and other Hebrew origin manuscripts. There are at least 3 source of Hebrew manuscripts extant in the DSS. The LXX, the MT and another source that doesn't match either the LXX or the MT. Some say there are 4 or 5 "streams" Hebrew texts in the DSS.
It is also interesting that the DSS contain non canonical writings from various sources. In other words the "canon" of the OT accepted by the MT and modern Judaism was not the canon of the Essenes. There have been various sects Jews that disagreed with one another for thousands of years. Even now, there are factions that vary significantly from one another. ( we do too).
Ultimately, someone made a choice for YOU. In the Bible you prefer today. You're basing your belief upon a verse that is not found in the LXX nor the DSS. It "magically" appeared in the MT and possibly some late Latin editions.
