Hillel the Elder

Hillel (Hebrew: הלל; variously called Hillel HaGadol, or Hillel HaZaken, Hillel HaBavli or HaBavli,. was born according to tradition in Babylon c. 110 BCE, died 10 CE in Jerusalem) was a famous Jewish religious leader, one of the most important figures in Jewish history. He is associated with the development of the Mishnah and the Talmud. Renowned within Judaism as a sage and scholar, he was the founder of the House of Hillel school for Tannaïm (Sages of the Mishnah) and the founder of a dynasty of Sages who stood at the head of the Jews living in the Land of Israel until roughly the fifth century of the Common Era.

He is popularly known as the author of two sayings: (1) "If I am not for myself who is for me? And being for my own self, what am 'I'? And if not now, when?" and (2) the expression of the ethic of reciprocity, or "Golden Rule": "That which is hateful to you, do not do to your fellow. That is the whole Torah; the rest is the explanation; go and learn."

Hillel was born in Babylon and, according to the Iggeret of Rav Sherira Gaon (a comprehensive history of the composition of the Talmud from the 10th century), Hillel descended from the Tribe of Benjamin on his father's side, and from the family of David on his mother's side.

When Josephus ("Vita," § 38) speaks of Hillel's great-grandson, Rabban Shimon ben Gamliel I, as belonging to a very celebrated family (γένους σφόδρα λαμπροῦ), he probably refers to the glory the family owed to the activity of Hillel and Rabban Gamliel Hazaken. Only Hillel's brother Shebna is mentioned; he was a merchant, whereas Hillel devoted himself to studying the Torah whilst also working as a woodcutter (Hertz 1936).
