The Book of Isaiah has likewise been subjected to the analytical test of the critic, and it is generally believed that the prophecies contained in the book have not all been written by the same author or in the same age. The book is divided into two large sections; the second section, from chap. xl. to chap, lxvi., is thought to have been composed shortly before the return of the Jews from Babylon. Although it is possible that anonymous prophecies were added to a book, the reasons which induced critics to make such a division are untenable. The first reason is the difference in style; but we must take account of the difference in the contents of the two sections. The prophecies in the first section have mostly a threatening tendency with regard to imminent punishment, whilst in the second section Israel is to be encouraged in his faith in the Almighty and in his hopes for a better future. It is but natural that the style should not be the same in both sections. Another reason for ascribing the second section to a later prophet is the fact that Koresh (Cyrus), king of Persia, is mentioned by name, and the fall of Babylon and the consequent deliverance of the Jews are described as well-known facts of the past. This and similar arguments are based on a misunderstanding of the character of the prophecies. The critics ignore the essential difference between the writings of inspired messengers of God and those of ordinary men. They deny to the man of God the power of foreseeing and foretelling coming events of which his fellow-men could not have any knowledge. By such arguments the critics set limits to the power and wisdom of God, and employ the same measure for both that which is Divine and that which is human. A Divine prophet has, by the Will of the Almighty, the future unrolled before him; he sees the catastrophe which is to come centuries later, and perceives its effect and its end. Even when he reviews the present state of affairs and takes the immediate future into consideration, his eyes frequently behold scenes and events of “the end of the days” (‏באחרית הימים‎), which he points out as the goal of our hopes and aspirations. When he warns, advises, or encourages his brethren with regard to their present wants, the virtues and the happiness of the Messianic age are not rarely introduced. Earlier events, though still future in time, appear then in the light of accomplished facts, and in their description the past tense is used instead of the future. Thus it happened that the prophet Isaiah, who flourished during the reign of King Hezekiah, could take his standpoint on the return of the Jews from Babylonia, look back at the exile as a thing of the past, and reveal to his brethren further troubles, the succeeding final redemption, and the ultimate triumph of the faithful and God-fearing over the faithless and wicked.
