RefTagger is a nice little program for bloggers that I recently added:
RefTagger is a free web tool that automatically turns all of your Bible references into hyperlinks to the passages at BibleGateway.com. RefTagger can also add an icon that is hyperlinked to the passage in Libronix and a tooltip window that displays the passage when you hover over the reference. So if your website says, "My favorite verse in the Bible is Romans 8:28," RefTagger will instantly turn it into this: "My favorite verse in the Bible is Romans 8:28."
