Revelations, the last chapter, verses 18-19, is the only book that has a dire warning about putting in or taking out any of the content of " this prophecy". I have read a few versions of this chapter and found that it is the only one not tampered with.
What I am saying is that, it seems that any other book in the bible is up for grabs or change.........except for this Revelations. I think I have hit upon something. It is that there is no caveat to protect the rest of the bible books, no evidence that this warning is back dated to apply to Genesis onward.
That leaves me with so many questions about the bible and various translations. I suppose I could point this out to my elder friend, but it would give him a heart attack.
