No section of the Old Testament has attracted more attention than has Isa. 40-55. The literature on it is more extensive than any one man could hope to read and digest in a decade. Yet Deutero-Isaiah will continue to attract exegetes so long as men study the Bible, for these sixteen chapters are as decisive and significant for an understanding of the Christian faith as are the sixteen chapters of Paul's Epistle to the Romans. Yet far less theological interest has been paid to Deutero-Isaiah than to the Epistle to the Romans. Unlike the majority of commentators, I have kept as closely as possible to the received Hebrew text; that is to say, I take a conservative view of the Masoretic text. Isa. 40-55 is a document of fundamental importance. The roots of most of Christian theology are to be found in it. Therefore its study is both essential and very rewarding. - Introduction.
