The Gemara in Eiruvin 13b describes how the three year argument between Beis Shamai and Beis Hillel culminated in a bas kol saying, “These and these are the words of the living God, and the Halacha is like Beis Hillel.” The Gemara goes on to explain that the psak is like Beis Hillel because of various good middos they had. We analyze these middos and discuss why they’re relevant for halachik psak. We also discuss the meaning of the bas kol.
