As of this blog posting date Amazon is giving away the English Standard Version (ESV) for free for the kindle or computer software that reads the kindle format! This is my pulpit Bible and favorite English translation. (The New American Standard Bible—NASB—comes second.)
To download the ESV for kindle click here.
Amazon is also offering the Holman Christian Standard Bible (HCSB) for free. I would compare it to the New International Version (NIV) in "feel." Not my favorite translational philosophy by any means but free is free.
