Free software with downloadable "modules" that expand the number of Bible translations and other study features.
Allows you to build a feature-rich, "custom" study system which includes a variety of commentaries, dictionaries, the ability
to make notations, develop a personal reading plan, etc. This is a MUST HAVE. - http://e-sword.net/
Unbound Bible – a great place to do research and to view the same text in multiple languages. A lot like e-Sword
above without having to download and install. - http://unbound.biola.edu/
