ר׳ יעקב בירב

ר׳ יעקב בירב (c.1474–1546), known as מהר״י בירב, was a Spanish-born Sephardi halakhist and the leading advocate of restoring classical semikhah in sixteenth-century Safed. Born at Maqueda near Toledo, he studied with ר׳ יצחק אבוהב. Expelled from Spain in 1492, he reached Fez, where tradition says the large refugee community chose the exceptionally young scholar as rabbi, and later served or taught in Tlemcen. His subsequent career took him through Jerusalem, Cairo, and Damascus before he settled principally in Safed, then the largest Jewish centre in Ottoman Palestine. Seeking a central court capable of resolving post-expulsion legal problems, he relied on a ruling of ר׳ משה בן מימון that consensus among the sages of the Land of Israel could renew ordination. In 1538 twenty-five Safed rabbis ordained him, after which he ordained ר׳ יוסף קארו, ר׳ משה מטראני, and others. ר׳ לוי בן חביב of Jerusalem rejected the procedure, generating an enduring halakhic controversy and a temporary retreat by ר׳ יעקב to Damascus. The chain nevertheless continued through several generations. He returned to Safed, where he died on 3 April 1546. His responsa were printed posthumously in 1663; exegetical notes survive in later rabbinic Bibles.
