The last four were all gifts; I must confess my limited ability to use them. I also used to have a Parallel Bible (RSV, KJV, NASB, and Modern Language Bible), a CEV, a Living Bible, and an Amplified NT, but I got rid of them when I last culled my library. The only thing I preach from any more is the RSV (not the NRSV, which I don't think I have a copy of, and don't want). I have occasionally consulted the Latin Vulgate online, but not frequently enough to download a copy.
How many different versions of the Bible do you have handy?
