Interesting. How about looking up the word "report" as in "field service report", or "congregation report"? Nah, I know that's not in the Bible at all...but I wonder how often it's in the publications?
The only problem I see with this thread (forgive me for being punctillious) is that it takes all the literature the Society produced for over fifty years and compares it to the Bible: take virtually any word and it will be used more by the Society in this way because you are comparing a very large sum of literature to just one book. All the same, I think you made a good point
