Considering that this site has oodles of study resources, such kind of things like Bible commentaries, Dictionaries, and lexicons of which are all free, I recommend you download as many as you would like to have. But that is not all, e-Sword has an incredibly great download manager which you can download for free some or all of the official resources such as different Bible translations, Dictionaries, Commentaries, and etc.
But it just doesn't stop there. You also have eStudySource.com, which holds all premium resources for e-Sword, of which you can purchase. The prices there are extremely reasonable.
So, as you can see, there is a great deal of wealth of Bible study resources available, of which the overwhelming majority of them are free.
Just as a matter of interest, from what I can gather, e-Sword has the largest repository of electronic Bible Study resources of any Bible Study software. Moreover, e-Sword enjoys a massive user support network of which a number of them create new resources almost daily.
What we have here could be regarded as the largest worldwide network of Christians creating resources for Bible study, of the quality that can be used in Bible College, University, and Theological Seminaries. I don't think that when Rick Meyers created e-Sword 18 years ago, Glory to God, that he would have dreamed this work would have gone to the extent and growth that it is today. And guess what?! And is still growing.
This is amazing, and one can really see God's hand in this work. And so with that, we can really give thanks and praise to God for raising men such as Rick Meyers and Josh Bond for the work they have done. And also Give God the glory, which He richly deserves, for those who tirelessly work in the creation of resources for this program. And I can honestly assert this, that to many this has been of a great cost to them.
Thanks for providing this information to me. It is such a valuable asset that I will definitely use.
