 In 1850, when Hayyim Parnes established a "yeshiva" for the education of rabbis, Barit was appointed principal ("rosh-yeshibah"), a position he held for twenty-five years until sickness forced him to resign.About twenty-five learned Talmudic students attended his lectures daily, and many of the eminent Russian rabbis and scholars were graduates of his "yeshivah".He was much admired for the logical and shrewd style of his lectures, which differed much from the scholastic and sophistic style of the Polish Talmudists of his time.
