Hungarian scholar; died at Nikolsburg, April 10, 1670. As successor to Gerson Ashkenazi he held the post of rabbi in Nikolsburg at the same time that he was chief rabbi of the province of Moravia. The epithet "Ḥarif" (The Keen Thinker) was also bestowed upon four of his ancestors, Ezekiel, Jacob, Ezekiel, and Isaac. Possibly he attained to the title by personal merit; for an inscription on his tombstone compares his death to the loss of the Ark of the Covenant.
