Proclaimers Book chap. 10 pp. 141-142 Growing in Accurate Knowledge of the Truth
The Bible Students were well aware of the many prophecies of restoration that were delivered to ancient Israel by God?s prophets. (Jer. 30:18; 31:8-10; Amos 9:14, 15; Rom. 11:25, 26) Down till 1932, they understood these to apply specifically to the natural Jews. Thus, they believed that God would show Israel favor again, gradually restoring the Jews to Palestine, opening their eyes to the truth regarding Jesus as Ransomer and Messianic King, and using them as an agency for extending blessings to all nations. With this understanding, Brother Russell spoke to large Jewish audiences in New York as well as in Europe on the subject "Zionism in Prophecy," and Brother Rutherford, in 1925, wrote the book Comfort for the Jews.
But it gradually became evident that what was taking place in Palestine with regard to the Jews was not the fulfillment of Jehovah?s grand restoration prophecies. Desolation came on first-century Jerusalem because the Jews had rejected God?s Son, the Messiah, the one sent in Jehovah?s name. (Dan. 9:25-27; Matt. 23:38, 39) It was becoming increasingly obvious that as a people they had not changed their attitude. There was no repentance over the wrongful act committed by their forefathers. The return of some to Palestine was not motivated by any love for God or desire for his name to be magnified by fulfillment of his Word. This was clearly explained in the second volume of Vindication, which was published by the Watch Tower Bible and Tract Society in 1932. The correctness of this position was confirmed in 1949, when the State of Israel, then recently formed as a nation and as a homeland for the Jews, became a member of the United Nations, thus showing that its trust was not in Jehovah but in the political nations of the world.
What had been taking place in fulfillment of those restoration prophecies pointed in another direction. Jehovah?s servants began to realize that it was spiritual Israel, "the Israel of God," composed of spirit-anointed Christians, who, in fulfillment of God?s purpose, were enjoying peace with God through Jesus Christ. (Gal. 6:16) Now their eyes were opened to discern in God?s dealings with such true Christians a marvelous spiritual fulfillment of those restoration promises. In time they also came to realize that the Jerusalem that was exalted at the end of the Gentile Times was not a mere earthly city, or even a people on earth represented by that city, but, rather, "heavenly Jerusalem," where Jehovah installed his Son, Jesus Christ, with ruling authority in 1914.?Heb. 12:22.

Yearbook 1934 Page 134The greatest and the most oppressive empire on earth is the Anglo-American empire. By that is meant the British Empire, of which the United States of America forms a part. It has been the commercial Jews of the British-American empire that have built up and carried on Big Business as a means of exploiting and oppressing the peoples of many nations. This fact particularly applies to the cities of London and New York, the stronghold of Big Business. This fact is so manifest in America that there is a proverb concerning the city of New York which says: The Jews own it, the Irish Catholics rule it, and the Americans pay the bills. [Emphasis added]
