Found this recently, and thought that I would share with you folks:

For those of you who may not already know what a concordance is, essentially its a sort of dictionary of words and their meanings, in this case with regards to hebrew and greek languages, which are the languages the bible is actually written in. Concordances are useful for understanding the exact meaning of a word, as sometimes the english translations are a little off, or may not necessarily reflect the right original meaning.
