a Jewish writer of Barcelona, was born about 1235, and died after 1300. He was a great authority and rabbi at Toledo. Being a good Talmudist he wrote some novellas on Talmudical treatises. He also wrote בֶּרֶק ה — בִּיַת, The Fixture of the House, a criticism on the תּוֹרִת ה — בִּיַת of Ben-Adrat, and the ס הִחַנּוּךְ, an exposition of the six hundred and thirteen precepts. It has, however, been questioned whether he is the author of the latter work. See Gratz, Gesch. 7:161 sq.; Rosin, Compendium der jud. Gesetzkunde aus dem XI V. Jarhdt.
