You couldn’t be more wrong.
There is negligible difference between the many ancient copies which are extant and the Bible we have today.
The Book is amazingly, miraculously, intact.
Sorry, but historians (to include Bible enthusiasts) have reviewed it and found at least two thousand changes....using a transcript that goes back to the Greek translation, which came after the Aramaic tribal editions were brought together for one single document. It is a document under constant revision....even in modern times.
