Etymology of the word "tefillin," translated in honor of the investiture of Rabbi Richard Hidary, which took place this past Shabbat at Shearith Israel.http://www.ketershemtob.com/tefillinetymology.htmlRabbi Hidary's inaugural talk was about Haham Gaguine's eldest son Rabbi Maurice Gaguine, who was Rabbi Hidary's great-uncle by marriage. He led with the description of Maurice's Yom HaTefillin in Vol. 1, p. 13, and since I had already translated that last year, I did the etymology section instead.
