It is with great sadness that Matzav.com reports the petirah of Rav Yeruchem Leshinsky zt”l, longtime maggid shiur at the Mirrer Yeshiva of Flatbush, who was niftar early this morning at the age of 89.

Rav Leshinsky was widely respected as a devoted marbitz Torah who shaped and influenced generations of talmidim through decades of unwavering harbotzas haTorah between the walls of the yeshiva. His shiurim, delivered with clarity, depth, and consistency, left a lasting imprint on countless bochurim who passed through his classroom.

He was born in Mir, Poland, before World War II, a child of a world that would soon be engulfed in churban. He was the son of Rav Dovid Leshinsky, and from a young age was immersed in a life of Torah and yiras Shomayim that would define him for decades to come.

Rav Leshinsky was zocheh to marry into one of the most prominent Torah families of the previous generation, becoming a son-in-law of Rav Avigdor Miller zt”l.

He was a brother-in-law of Rav Aharon Kreiser zt”l and Rav Shmuel Brudny zt”l.

He spent his life immersed in Torah, dedicating himself fully to the Mirrer Yeshiva, where he learned, taught, and lived with singular focus and mesirus nefesh. His presence in the yeshiva spanned many years, during which he became a cornerstone of the institution’s harbotzas haTorah.

Rav Leshinsky is survived by his wife, Rebbetzin Libby Leshinsky, along with his children: Rav Shmuel Leshinsky, Rav Avrohom Nochum Leshinsky, Reb Yitzy Leshinsky, Mrs. Avigayil Klein, Mrs. Batsheva Alpert, and Mrs. Shulamis Fishoff.

He was predceased by his siblings: Rebbetzin Rivka Kreiser, wife of Rav Aharon Kreiser; Rav Yaakov Leshinsky; and Rebbetzin Rochel Brudny, wife of Rav Shmuel Brudny.

The levayah is being held at the Mirrer Yeshiva in Brooklyn, New York. Following the levayah, the aron will be flown to Eretz Yisroel for kevurah.

With his petirah, the yeshiva world has lost a true oved Hashem and marbitz Torah, whose quiet dedication and lifelong commitment to limud haTorah will continue to resonate through the many talmidim he inspired.
