The WTS had a different approach about the Jews during Russell's and Rutherford's early years.
The WTS felt that they Jews would be reinstated as a nation on earth.
James Penton said:
During the first half of their history, the Bible Student-Jehovah's Witnesses were
notable for their sympathy to the Jews. Even more than most late nineteenth- and
twentieth-century American Protestant premillennialists, the Watch Tower's first
president, Charles T. Russell, was a thoroughgoing supporter of Zionist causes. He
refused to attempt the conversion of the Jews, believed in the Jewish resettlement
of Palestine, and in 1910, led a New York Jewish audience in singing the Zionist
anthem, Hatikva. [1] For more than a decade after Russell's death in 1916, Judge
Rutherford followed in his footsteps.
In 1925 he produced a small book entitled Restoration, based on a series of radio
broadcasts he had given, and in 1926 he published a similar volume called Comfort
for the Jews. In both, he proclaimed himself a friend of the Jewish people and
asserted that Jewish migration to the ancient Holy Land was a fulfillment of
biblical prophecy. Identical Publisher's Forewords to Restoration and Comfort for
the Jews stated:
THE rebuilding of Palestine is claiming the attention of Jews throughout the
earth. Some of the Gentile world powers are outwardly favoring the
movement but manifestly for selfish reasons.
JUDGE RUTHERFORD, known throughout the world as a friend of the
Hebrew people, is vigorously supporting the claim of the Jews to the Holy
Land. He is opposed to proselytizing the Jews, holding that such is not only
wrong but contrary to the Scriptures. His lectures to large audiences, which
have been broadcast throughout the world, on "JEWS RETURNING TO
PALESTINE", have created an intense interest. There is a good demand for
them in printed form. He has simplified these lectures and now presents
them in book form. This volume will be of profound interest to Jews and
Gentiles alike. It is the first unbiased presentation of the subject from the
Scriptural viewpoint published.
The Publishers send forth this volume confident that it will do much good.
In 1930 Rutherford produced a larger volume on the same theme called Life.But
suddenly he repudiated his beliefs respecting the Jews. Life was withdrawn from
circulation,[2] and in 1932 Rutherford proclaimed that "fleshly Israel" had no
specific role to play in salvation history.
