Rabbi at Leghorn, Italy; died before 1788. A follower of the Cabala, he was highly respected by his contemporaries for his knowledge and his piety. He published "Siaḥ Yiáºá¸¥aḳ" (Leghorn, 1766), novellæ to the treatise Yoma, with comments and emendations to the "Tosefot Yeshanim" to Yoma. The second part of this work, containing novellæ to the treatise Ḥagigah, together with a treatise on the prayers, especially on the "Shemoneh 'Esreh," was taken from his manuscript work "Bet Yiáºá¸¥aḳ" which discussed a portion of the legal code "Oraḥ Ḥayyim," and was printed posthumously by his son Jacob, with the latter's additions, under the title "Ḥedwat Ya'aḳob" (ib. 1788).
