Rabbi Ben Zion Abba Shaul (1924–1998) was a towering Sephardic posek (halachic decisor), Talmudic scholar, and the revered Rosh Yeshiva of the flagship Porat Yosef Yeshiva in Jerusalem.

Widely considered one of the ultimate legal authorities for Sephardic Jewry in the late 20th century, he was celebrated for his absolute independence of thought, his razor-sharp analytical genius, and his legendary humility. While his contemporary, Rabbi Ovadia Yosef, was famous for an expansive, encyclopedia-backed style of legal writing, Rav Ben Zion was known for his concise, conceptually driven approach to Jewish law.

Early Life and the Porat Yosef Golden Era

Rav Ben Zion was born in Jerusalem under the British Mandate, the eldest of sixteen children born to Eliyahu and Benida Abba Shaul, immigrants from Persia (Iran). His father was a deeply pious factory worker who dedicated his spare time to Torah study.

• The Young Prodigy: At just 11 years old, he entered the prestigious Porat Yosef Yeshiva in the Old City.

• The Star Student: He became the prize disciple of the legendary Rabbi Ezra Attiya, the spiritual architect of modern Sephardic scholarship. Rav Ben Zion possessed a photographic memory and an uncanny capacity for deep, logical analysis.

• The Ultimate Study Partnership: As a teenager at Porat Yosef, he formed an intense, lifelong study partnership (chavrusa) with Rabbi Ovadia Yosef. The two young prodigies would spend up to 15 hours a day arguing over Talmudic texts, fundamentally sharpening each other's intellectual toolkits.

Leadership of the Flagship Yeshiva

Following the passing of Rabbi Ezra Attiya and Rabbi Yehuda Tzadka, Rav Ben Zion was elevated to the position of Rosh Yeshiva of Porat Yosef.

Under his leadership, the yeshiva maintained its status as the "Harvard of the Sephardic World," drawing the most elite young minds from across Israel, North America, and Europe. Unlike many heads of schools who focused solely on theory, Rav Ben Zion meticulously trained his students in practical jurisprudence, grooming them to become communal rabbis, educators, and dayanim (rabbinical judges) capable of leading a global Sephardic renaissance.

Halachic Approach: Ohr L'Tzion

Rav Ben Zion’s lasting literary monument is his multi-volume collection of responsa titled Ohr L'Tzion (Light of Zion). His method of determining Jewish law differed fundamentally from many of his peers:

• Conceptual Logic Over Precedent: While Rabbi Ovadia Yosef's style was to quote hundreds of historical authorities to prove a point, Rav Ben Zion preferred a highly structured, analytical approach. He would break a case down to its core Talmudic concepts, using logic to derive the final ruling, often resulting in highly concise, definitive answers.

• Preserving Local Customs: He was a fierce defender of local Sephardic and Middle Eastern traditions. He argued that Sephardic Jews should not feel compelled to adopt Ashkenazi stringencies, nor should they discard their own ancestral customs (such as those rooted in the traditions of the Ben Ish Chai or the kabbalists of Jerusalem) in favor of a entirely uniform code.

Character, Humility, and Asceticism

Despite his massive influence and the fact that thousands of people globally sought his guidance, Rav Ben Zion lived a life of extreme simplicity and physical suffering.

• Physical Hardship: In 1983, he suffered a severe, debilitating stroke that left him partially paralyzed and caused him immense physical pain for the remaining 15 years of his life. Despite this, he refused to stop teaching, continuing to deliver deep lectures and answer complex legal queries from his wheelchair or bed.

• Extreme Accessibility: He lived in a modest apartment in the Geula neighborhood of Jerusalem. He was famously gentle, soft-spoken, and infinitely patient, regularly prioritizing helping broken-hearted widows, orphans, and struggling yeshiva students over his own high-stakes scholarly work.

Stance on Politics

Unlike many of his close friends and colleagues, Rav Ben Zion deliberately kept his distance from the messy arena of Israeli party politics.

• When the Shas party was formed in 1984, he gave it his blessings and immense moral support because he believed in rebuilding Sephardic pride and funding religious infrastructure.

• However, he explicitly declined to formally join its ruling Council of Torah Sages (Moetzet Chachmei HaTorah), preferring to remain entirely independent and untainted by political compromise, viewing his true home as the study hall.

Passing

Rabbi Ben Zion Abba Shaul passed away on July 13, 1998 (19 Tammuz 5758), at the age of 74.

His passing plunged the global Sephardic world into profound mourning. His funeral procession through the streets of Jerusalem was a massive, historic event, drawing an estimated 200,000 mourners who paralyzed the capital city to pay tribute to a master of law who combined a giant intellect with the tender heart of a father. He was buried in the Sanhedria Cemetery.
