8:28-33; Rom. 10:16, 20, 21.  That they were appended by fraud and forgery no one pretends to affirm.  The character of this part of the book, not less than the character of those who had the Jewish canon in custody, is a sufficient protection against such a supposition.  That they should have been appended through ignorance is inconceivable.  How can the name of so great a prophet have remained unknown?  According to the hypothesis in question, he lived about the close of the Babylonish captivity.  He was contemporary, therefore, with Daniel; with Zerubbabel also, Jeshua, and the other chiefs of the restoration.  Did no one of these know who was the man that prophesied so abundantly of the work which they had so much at heart?  And did his name indeed escape the knowledge of the learned scribe Ezra?  And if they did not know his name, why did they append his writings to those of the true Isaiah, thus tacitly ascribing to him their authorship?  Why did they not leave them without a name, as they did the books of Judges, Ruth, Samuel, Kings, and Chronicles?  That these chapters have always constituted a part of the book of Isaiah, and been acknowledged as such, is a fact which admits of but one explanation; that, namely, of their genuineness.  The Great Unknown, as he is called, is no other than Isaiah himself, whom the principles of certain critics do not allow them to acknowledge as Isaiah.

The internal evidence for the genuineness of these chapters has already been partly considered in an incidental way.  It is found in the purity of the Hebrew, which belongs to the age of Isaiah, not of Cyrus; in the undeniable allusions to the temple sacrifices and oblations as then existing (43:23, 24), and to the sin of seeking heathen alliances (57:9); and especially in the fact that a writer living near the close of the exile must have referred in a more particular and historic way to the great events connected with Cyrus’ conquests.  It may be added that there are in the later prophets some clear allusions to this part of Isaiah.  Jeremiah, who undeniably made use of prophecies contained in the first part of Isaiah, was acquainted with the second part also.  Compare Jer. 10:3,4, with Isa. 40:19, 20; 41:7; Jer. 31:35, with Isa. 51:15, where a whole clause is repeated from Isaiah, which agrees in the Hebrew to every letter; Jer. 50:2, with Isa. 46:1, 2.  Compare also Zeph. 2:15, with Isa. 47:8; Nah. 1:15, with Isa. 52:7.

9.  The arguments urged against the genuineness of certain sections of the first part of Isaiah are for substance the same as these that have now been examined, and need not a separate consideration.  We come on solid grounds to the conclusion that Isaiah was the author of the whole collection of prophecies which bear his name, and that the arrangement of these prophecies in their present form also proceeded from him.
