The Torah world is mourning the petirah of Rav Yosef Sholom Halevi Weinfeld zt”l, a distinguished mechaber seforim whose lifelong work opened the door for countless Yidden to access and understand foundational sifrei kodesh. He was niftar Thursday night at the age of 82.

Rav Weinfeld zt”l was widely recognized for his acclaimed “Yesod Malchus” commentary, as well as for his leadership of the historic “Eshkol” publishing house, which for generations has played a central role in the dissemination of Torah literature.

He was born on ט”ו אייר תש”ד (1944) to his father, Rav Yaakov Shaul Weinfeld zt”l, author of Mishnas Yaakov and founder of the Eshkol publishing house, and his mother, Mrs. Rachel Goldberg a”h, daughter of Rav Tzvi Hirsch Goldberg zt”l.

In his younger years, he learned under the Vizhnitzer Rebbe, the Yeshuos Moshe zt”l, from whom he later received warm haskamos on his seforim.

After the petirah of his father in תשמ”ט (1989), the publishing enterprise was divided among the brothers. His brother, Rav Shmuel Yehuda Halevi Weinfeld, went on to establish the Shai L’Mora publishing house, while Rav Yosef Sholom zt”l continued at the helm of Eshkol, where he significantly broadened its scope and impact.

Under his guidance, Eshkol produced a vast array of seforim, many featuring clear and structured explanations that greatly assisted lomdim in their limud and tefillah.

His most well-known contribution, the Yesod Malchus system, offered a unique word-by-word explanation printed alongside the original text, allowing readers to immediately grasp the meaning without needing to search through multiple mekoros. This approach provided both clarity in understanding and ease of use, making it especially valuable for a wide range of learners.

Over time, this commentary was published on many central sifrei kodesh, including Tehillim, siddurim, machzorim, Chumash, Nach, and zemiros of Shabbos, and was widely regarded as an innovative and practical format that enhanced accessibility to Torah.

Among the many seforim distributed by Eshkol are the well-known siddur Tefillas Kol Peh, and menukad editions of the Shishah Sidrei Mishnah, all of which found their way into kehillos around the world.

The levaya took place on Friday in Yerushalayim, and he was brought to kevurah on Har HaZeisim.

Yehi zichro boruch.
