The fallen nephew of OU administrator honored at OU’s worldwide Yom HaZikaron commemoration and siyum.

(Courtesy of OU) At only 32 years old, Master Sgt. Zechariah Pesach Haber, HY”D of the 14th Armored Brigade’s 87th Battalion, was a rising star. The Jerusalem resident tragically fell in a northern Gaza battle on Jan. 16, while on reserve duty. Zechariah’s death was particularly painful for the Orthodox Union family, as he was the beloved nephew of OU Chief Strategy Officer Rabbi Ilan Haber.

Born in Teaneck, Zechariah was eight years old when he made aliyah in 1999 with his parents Aharon and Miriam, and four younger brothers. Known for his modesty, kindness and infectious smile, Zechariah’s greatest sources of pride were his dear wife Talia Zehava, and their three precious children.

“Zechariah was righteous, loved Torah and loved people,” recalled Rav Amnon Bazak of Yeshivat Har Etzion, where Zechariah studied. “He had a heart of gold, was always happy and smiling, talented and serious in all his actions.”

Zechariah deeply appreciated nature, and was known as his family’s resident botanist. Intending to channel his passions into a career, Zechariah earned bachelor’s and master’s degrees with honors in plant science from Hebrew University. He dreamed of modernizing agriculture through innovative technology, and at the time of his death, Zechariah was about to complete a Ph.D. in plant sciences and food security at Tel Aviv University.

“Zechariah was an incredibly kindhearted, thoughtful person, who had a tremendous curiosity about the world,” reflected Haber. “He was genuinely interested in meeting people from different walks of life, and could learn from anybody. He was very disciplined about the things he felt were most important in life. At the same time, he also had a sense of humor and could joke around. He liked hiking and the outdoors, and was totally devoted to his wife and children, with whom he loved to play. He was brilliant in both Torah and science, and was very accomplished, even in his short life.”

In memory of Zechariah and all of the chayalim who gave their lives Al Kiddush Hashem, the OU held a worldwide siyum of Shas, mishnayot and Tanach on Monday at a live streamed Yom Hazikaron Commemoration.

“This year, when so many are grieving their raw and fresh losses, it is a special opportunity for pure and unadulterated empathy as we try our hardest to understand and to relate to the experience of those who have sacrificed their lives for us, for Klal Yisrael, whom no one in the world can approach in their greatness,” said OU Executive Vice President Rabbi Moshe Hauer.

Monday’s Yom Hazikaron Commemoration and siuym included remarks by OU President Mitchel Aeder; Rabbi Hauer; RIETS Rosh Yeshiva Rabbi Yaakov Neuburger, who serves as the rabbi of Congregation Beth Abraham in Bergenfield; Binghamton University’s OU JLIC (Jewish Learning Initiative on Campus) Director Rabbi Ben Menora, and the Haber family.

The siyum Tanach was led by Hauer; the Siyum Mishnayot was conducted by World Mizrachi Movement Executive Chairman Rabbi Doron Perez, father of Capt. Daniel Perez, HY”D; and the Siyum HaShas, Hadran and Kaddish were led by Yeshivat Hesder of Sderot Rosh Yeshiva Rabbi Dovid Fendel.

The event was emceed by OU Managing Director of Community Engagement Rabbi Yaakov Glasser, who serves as the rabbi of New Jersey’s Young Israel of Passaic-Clifton. Great Neck Synagogue Chazzan Yitzy Spinner sang the Mishebererach L’Chayalim and Kel Malei tefillot.

Ahead of Yom Hazikaron, the OU launched B’Yachad LaNetzach, a unique initiative which encouraged North American shuls, batei midrash and schools to join the families of the fallen in recalling and appreciating their profound sacrifice by memorializing a single soldier who has passed away since Oct. 7.

“Thanks to this incredible initiative, those who sacrificed their lives are not getting lost in the numbers,” said Haber. “Rather, they are being recognized individually for how they lived and engaged with others, and what they accomplished. Linking shuls with specific chayalim so that they can connect with them is a very poignant and appropriate way of recognizing Yom Hazikaron and valuing everyone’s contributions toward the state of Israel’s establishment and continued existence.”

B’Yachad LaNetzach aims to bridge the significant gap between Israelis who serve in Tzahal and the vast majority of American Jewry who cannot fathom the emotional burdens Israelis bear around the war. It also endeavors to offer bereaved families chizuk, and elevate the neshamot of the departed. Participating organizations received a metallic print and bio of their adopted soldier, as well as a connection with their family, where possible.

“Our kedoshim deserve to be remembered individually by having their stories told and by having Torah learned and tefillot said in their memory,” said Hauer. “Each and every one of their families deserves to know that their sacrifice is recognized as having been on behalf of all of Klal Yisrael.”

Haber is tremendously moved by the OU’s gesture to memorialize Zechariah.

“That the OU chose my nephew to specifically recognize has a deep personal meaning to me, given my long-standing connection with the OU, working first with JLIC and now with OU management. The OU is not just an organization, but a family.”
