Lot of two autograph letters by R. Tzvi Yehuda Kook clarifying important elements of his father’s ideology.
Dated 1963, responding to a scholar in New York who noticed a ruling from Rav Kook in the book Jewish Thinkers, permitting youth in Tel Aviv to play soccer on Shabbos. The scholar had then requested of R. Tzvi Yehuda to clarify his father’s position on the matter. R. Tzvi Yehuda replied, expressing his shock to hear this, insisting it was a blatant lie, adding that his father had actually published many letters and proclamations forbidding the abovementioned practice. Additionally he enclosed a precise transcript of Rav Kook’s 1931 halachic responsum prohibiting the practice, which he gives permission to publish. (Halachic transcript included in lot)
Dated 1964, responding to a scholar in New York who had written to R. Tzvi Yehuda, asking him to clarify a position attributed in a periodical to Rav Kook, attesting that the commandment to settle the land of Israel is greater than the commandment to wear Tefillin (phylacteries). R. Tzvi Yehuda responds that, having heard nothing of the sort from his father, he can neither confirm nor deny the report. However, he references the Chasam Sofer in Sukkah (36a) which discusses the importance of Yishuv Eretz Yisrael in connection with the Mitzva of Tefillin. R. Tzvi Yehuda concludes that in any event this in no way diminishes the importance of Tefillin but rather emphasizes the importance of yishuvha’aretz.
