I do not use one volume commentary’s like I once did. Those that I did use were the following: Barnes (on NT); I still like Barnes. Edersheim on OT History; When I was in Desert Shield, it was his volume that I took with me. At that time we were in post-combat mode, and I was able to read it through. It is an old work, but I still like it. I have often reflected on my library and what it would be that I feel compelled to keep if I had to whittle down. Of the one volume books, these would be two that I think I would hold on to.
