With regards to the whole "Baylonian Exile" thing, to me it sounded supsiciously like priming. I have noticed over the years, that they make a point of setting up some tenuous Bible precedent in answer to a question no one was asking in the lead up to a more major adjustment and prior to actual announcement -( sorry if that's hard to follow.)
Which caused me to wonder what adjustment or announcement was coming in the future that depends upon this "adjustment."
