In addition to arguments made elsewhere by others, if one makes 3 sets of words from KJV text:

Set 1 includes all the words that appear in the Bible between Genesis through Acts plus those in James through Revelation. These words are Bible words used by the various Bible authors. For the moment leave Paul's writings and the author of Hebrews out of consideration.

Set 2 include all the words that appear in Romans through Philemon. These are the words of Paul and may also include many of the words that also appear in set 1.

Set 3. All the words that appear in Hebrews. These are the words that were used by the author of Hebrews.

What words appear in set 2 that are not in set 1?
These are words that only Paul used.
