This volume upon Isaiah xl.-lxvi. carries on the exposition of the Book of Isaiah from the point reached by the author's previous volume in the same series. But as it accepts these twenty-seven chapters, upon their own testimony, as a separate prophecy from a century and a half later than Isaiah himself, in a style and on subjects not altogether the same as his, and as it accordingly pursues a somewhat different method of exposition from the previous volume, a few words of introduction are again necessary.
