I have the complete, unabridged, single volume commentary of Matthew Henry. You could murder a moose with this thing. I also have at least half a set of commentaries by J. Vernon McGee that was gifted to me by one of my Elders. I have John Calvin's commentary on the Book of John with the spicy foreword from our hero. I think I have a few more floating about somewhere and I've "lost" a great many too earnest seekers of knowledge with the promise "I'll get this right back to you."
