Choosing a random verse – 2 Nephi 5:6… There are 1,839 exact matching 3+ word strings from the Bible and Apocrypha.
…and that is only ONE VERSE.
Granted, many three word strings are common, but 4+ strings are more difficult to explain away.
If this were the average then there would be more than 12,000,000 exact matching 3+ word strings ‘borrowed’ from the Bible in order to create the Book of Mormon.
