Use dwdiff to create word diffs between verses.

The syntax that I like displays the revised version with the additions bolded.

An example, 1 Chronicles 21.15:

15 And God sent an angel unto Jerusalem to destroy **it. And the angel stretched forth his hand unto Jerusalem to destroy it;** and **God said to the 
angel, Stay now thine hand, it is enough; for** as he was destroying, the Lord **beheld Israel, that** he repented him of the **evil; therefore the Lo
rd stayed** the angel that destroyed, **as he** stood by the **threshing floor** of **Ornan,** the Jebusite.
