"Is there any reason to believe that God could not get A Book to us as He intends? "
A God "could" "get A Book to us as he intends", but if He gave dominion to humans and/or Elohim over everything on earth, then the question is "would God allow humans and/or elohim to change it in different texts?"
"God" could be translated YHWH, Elohim, and etc. If that book is called The Bible, The Dead Sea Scrolls, or the Torah, then Jeff Brenner of Ancient Hebrew Research Center, Mark Biltz of El Shaddai Ministries and others are bringing more clear understandings of the actual texts.
Also we all have slang or other terms that could be interpreted differently as well as word meaning changes and the context as would be understood by the original recipients of the Book.
