Beit Hillel (“house of Hillel”) was a school of thought originating with the sage Hillel, traditionally seen in rivalry with Beit Shammai. The school followed Hillel’s more moderate and expansive approach to Jewish law. Among its outstanding personalities was Rabban Yochanan ben Zakkai, who finalized the ascendancy of this school of thought over the Bet Shammai. The Talmud (Eruvin 13b) recounts a heavenly voice eventually deciding in favor of Beit Hillel in all cases due to its members' humility and pleasant ways. Nevertheless, the Talmud also records exceptions wherein the law follows the opinion of Beit Shammai.
