A.G. Clarke wrote the bulk of his Analytical Studies in the Psalms, while in a Japanese internment camp in China during WWII. Kregel and Richtie have published editions of this title. I have a hardcover from Kregel. It is an excellent work that gives a detailed analytical outline of each psalm, along with comments on many of the verses, as well as prophetic and personal implications.
I highly recommend this work.
If anyone has reviewed his work on Song of Solomon, please drop me an email.
