a famous Jewish teacher of the 18t century. of our aera, was one of the most celebrated disciples of Jochaanan ben-Zachai (q.v.). One of his recorded maxims is found in Aboth, 2:19: "Be quick to study the law, and know what thou shouldst return inl answer to the Epicurean, and remember before whom thou laborest; for the master who employed 'thee is. faithful, and will recompense thee the reward of thy toil." As a teacher, he was so highly esteemed that to attend his lectures was regarded like fulfilling a commandment (Cholin, fol. 106).
