Pastor John MacArthur received this commentary from his professor when he graduated from seminary. So I think this is a good product. But, I purchased it for my Dad so, I haven't look into it personally.
This is a well-written and masterly piece of sound Christian and evangelical scholarship on the Old Testament - the original source of the evangel; and the source that the inspired apostles used so well. The Old Testament is not used nearly enough by us as the rock of faith in Christ who is the Rock of the Church. These well tried volumes will help us all to put that wrong right. Well produced and a pleasure to read.
I was familiar with this work from seminary days. Because of it's age, it lacks much of insights from recent archeological and textual research. However, the price was too attractive to pass up. Due to the age and very conservative approach of the work, I always use it in conjuction with more recent and more moderate commentaries.
