Talmudist; born at Wilna, Russia, about 1735; died in Safed about 1785. The congregation at Hebron in 1765 sent him as their emissary (meshullaḦ) to Persia. On the out-break of a war in 1775, Bozrah, the city in which he resided, was besieged; but he, his wife, and new-born son, Eliezer JeruḦam, escaped and settled in Safed. He celebrated his deliverance in Hebrew verses called "Megillat Paras" (The Roll of Persia), published by his grandson, R. Jacob Saul Alyashar, in "Ish Emunim" (Jerusalem, 1885).
