I have always been grateful to the folks at Crossway for making the English Standard Version freely available for e-Sword. While other modern versions are available for e-Sword at a modest price, the ESV is completely free, including introductory notes for each book, cross-references, and maps.

If you haven’t checked out e-Sword yet, I highly recommend it as the best free Bible study program available. There is also a large community of advanced users constantly developing free resources for e-Sword.
