RABBI, born at Babylon, 112 B.C. He went to Jerusalem to study law at the age of 40. When 80 years of age he became chief of the Sanhedrin. He was one of the compilers of the Talmud, and is regarded by the Jews as the most learned of their doctors. He gave instruction in the laws and traditions to more than a thousand pupils. His master was Shammai, with whom he did not agree on some points. The difference became a quarrel, warmly taken up by the disciples of each, and ending in some bloodshed.
