Hello,
Is there any way to make a vocabulary list for a particular book of the Bible (Romans) for all Koine Greek words that occur 20 times or less in the whole New Testament? I'm wanting to exclude common words like kai as well as words that occur infrequently in Romans but frequently enough through the rest of the New Testament (for instance, adelphos occurs 19 times in Romans but 342 in the whole New Testament, so I'm wanting to exclude it).
