Responsa concerning a case of “Shomer Shemesar Leshomer” and other matters.

The Ga’on Rabbi Yitzchak Ya’akov Rabinowitz (R. Itzele Ponivezher) was among the disciples of the Beis HaLevi and studied with his son, Rabbi Chaim Soloveitchik. In 1889 he headed the Slabodka Yeshiva before leaving to serve the rabbinate of Ponevezh. He was an intellectual giant in Torah and originated new paths in the conceptual understanding of Talmud. R. Itzele’s responsa were posthumously published under the title Zecher Yitzchak.
