The Highway Forums General Discussion Theology Discussion Forum Job

Here are some which I have found very helpful:

1. The Argument of the Book of Job Unfolded, by William Henry Green, D.D. (republished by Banner of Truth under the title, Conflict and Triumph)
2. Sermons from Job, Calvin's Sermons
3. An Exposition of Job, by Joseph Caryl
4. Commentary on the Old Testament - Job, Keil & Delitzsch

I haven't done a search to see if all of these titles are still in print. Most of my library consists of books that were published back in the "good old days". Some of the publishers of these books no longer exist. However, there are some good used book dealers who often have copies of such books.
