Logos has made available a free BibleWidget for users of Mac OS X Tiger. It is based on the KJV, and can be used for simple text searches, by entering (or cutting and pasting) the book followed by the chapter and then the verse number (no ranges).

If you want to try it, here’s what you have to do: download it, unzip it, drop the widget inside your user’s Library/Widgets folder, and you’re ready to go!
