e-Sword is a very nice free Bible program with lots of features. It is available at here.
I mentioned the e-Sword Bible program in my Instructable "Learn New Testament Greek."
Later in this Instructable I will refer to some steps in that Instructable rather than duplicate information.
Download the basic program ("application installation"--16.6 MB). Install it.
In the drop down menu you can see various categories of add-on modules that are also available. Most are free. Some require you to pay a copyright royalty fee.
e-Sword is not available for Macintosh or for Linux, but you can find somewhat similar programs for both of those.
