The problem is very simple, there doesn't exist one Bible, or scripture, either written in Hebrew or Greek or any other language that is complete.
First of all, the scripture formed beyond 3,000 years ago. King David was about 1,000B.C. and Moses is at least 1,000 years ahead. Consider all other family member, the very first one should be written about 4,700 years ago. Even the old testament was not totally finished by 3,000 years ago either. Anyway, let's admit it is correct.
Second, no one know for sure what was origianlly written. Though Jews passed down books word by word very carefully, there are still errors and mistakes made. The Dead Sea Scroll, the oldest one that is physical evidence, show much difference from later editions.
So, if words are not precise, with more or less letters in between, the base methodology is laughable.
