*A unique word only occurs only once in the Bible. This book is a list of all the verses in the Bible that have two or more unique words. Many of the words are names, but others provide material for interesting word study.
I find it useful in the margin link area of the Bible pane.
The list is sorted by number of unique words in descending order and then by book of the Bible. Here's a snippet showing verses with 5 unique words in the New Testament.
