Grammarian, scribe, and dayyan of Lemberg in the eighteenth century. He wrote: "Shirah Ḥadashah" (Zolkiev, 1764), a Hebrew grammar in verse, divided into six poems with explanations in prose, composed after the model of Elijah Levita's "Pereḳ Shirah"; "Ohel Mosheh" (ib. 1765), a complete Hebrew grammar in four parts, following Ḳimḥi's "Sefer ha-Zikkaron" and criticizing Zalman Hanau (RaZaH); also "Halakah le-Mosheh," novellæ on the Talmud and decisions; and "Ohel Mo'ed," a treatise on the Hebrew language, both of which works are still unpublished.
