George Knight has produced a very fluent and readable commentary on these important chapters of the book of Isaiah, which, more than any other part of the Old Testament, anticipate the Cross of Christ. By concentrating on the theological issues that are raised and by adopting a non-technical style of presentation, Knight introduces the reader to some of the leading motifs of biblical theology. In view of the complex questions which relate to the structure and unity of the book of Isaiah, I believe that all who share an evangelical faith and who have regard for the theological importance of the Old Testament will find this commentary rewarding and enriching.
