Current King James version held as authoritative by many has 39 books in Old Testament, 27 in New Testament. 39 is 3 x 13, 13 being a favorite Satanic number and triples of their numbers being considered especially powerful according to some sources (for instance, 3x11=33. see page:
https://amos37.com/no13/ ). 27 is 3 x 9, 9 being another favorite Satanic number, tripled here, again. 27 also reduces to 9, 9 representing ego, emptiness or lack of progress as I've come to understand it (see image below).
(last two images are from Mark Passio præsentations).
66 Bible books is also 66/666 = 2/3 = .666, so one can find another 666 encoded there if one chooses to.
All in All, that's a suspicious number of occult-derived code numbers in the layout of the King James version.
'
For I testify unto every man that heareth the words of the prophecy of this book, If any man shall add unto these things, God shall add unto him the plagues that are written in this book: And if any man shall take away from the words of the book of this prophecy, God shall take away his part out of the book of life, and out of the holy city, and from the things which are written in this book.'
Revelation:22:18-19
- but there's little reason to assume a Satanist would heed this warning, and would of course just leave the warning as is, in order that it may appear authoritative.
