This is a great verse by verse comprehensive insight into the book of Isaiah. Out of a few different commentaries that I've looked into for my study on Isaiah this will be my preferred choice. It's very readable and enjoyable for any student or Bible teacher as well.
This is my second set. The first is in my office at home. I use this set so much, until I purchase a second set for my office at work. If you are a pastor, or teacher of the WORD, you will need this set for sure!!!
