I can think of no other commentaries in my library that offer such depth and insight for the student, layman, or those who desire good exegetical material. It should be a must for any person who desires contextual analysis of Scripture. I use my Bible, The Pulpit Commentary, and Strong's Concordance for personal devotion, teaching, and preparation for sermons regularly.
Having just started my first pastorate, I've begun to realise how lacking my library is in commentaries, especially practical ones on OT books. Although any set is going to be hit or miss, it is always helpful to own one to ensure adequate coverage across the Scriptures especially if asked to prepare something at short notice and this has been a great purchase and one that will serve me well for the future.
The format is a fairly detailed expository commentary on each chapter of Scripture, followed by suggestions for preaching and several sermon skeletons for further ideas. Although it is true that a number of the sermon outlines "creak" a bit (it is over a hundred years old!), in general much of their application is spot-on and with prayer and thought are very helpful for preparation for the pulpit. Again, although the commentaries don't engage with modern scholarship, they do tend to grapple well with the text and there is much here that is still very helpful, especially when used in conjunction with more recent works.
Lest anyone think they are only useful for the preacher, I have just finished reading through Kings with them, and have profited greatly personally from the volume covering it- so much so that I have just bought Davis' commentaries on Kings to consider preparing a sermon series on them!
The bindings seem strong and attractive and the print is readable, and whilst they are available digitally, there is much to be said for getting them in a printed format to allow for scribbling and note-making. For the price they really are super value and worth purchasing for any preacher/minister, and arrived very quickly too.
