Bible Study Software with Bible commentaries

I need a bible study software created. Id like it to have a combination of these features. These programs are Free and also the Bible is not copyrighted, so Im not sure if you can use parts of these to combine into my program.

Because these are free programs, im not sure if this is legal or not.
