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.
