Polish darshan, or preacher: flourished in the seventeenth and eighteenth centuries. He was the great-grandson of Issachar Baer, surnamed Baerman Ashkenazi, the commentator of the Rabbot. At Amsterdam, in 1673, he edited his grandfather's work. "Mareh Kohen," to which he added an introduction. Subsequently he was stricken with blindness. Forty years later, being then well advanced in years, he published his own work, "Ori we-Yish'i" (Berlin, 1714), containing a selection of his sermons, treating of repentance prayer, and charity. The title of his work, "My Light and My Salvation," was suggested by the facts that he had regained his sight, and that he had had a fortunate escape from a dangerous fire.
