Your word is a lamp to walk by,
and a light to illumine my path. (Psa 119:105 NET)
Esword allows you to study the bible on your PC and has a wealth of features so that you can get under the hood of each scripture by looking at the original language. The best part is its free! You can search for free modules to add to it such as different versions of the bible and dictionary's, concordances ect. The modules just have to be placed in the installation folder and then restart the program.
