Rabbi Dosa ben Harkinas

Once two witnesses testified before Raban Gamliel that they had seen the new moon for the month of Teshrai, yet the next night it was nowhere to be seen and he accepted their testimony. Rabbi Dosa ben Harkinas argued saying there were surely false witnesses for how can one testify that a woman gave birth, yet the next day she was seen still pregnant.  When [[Rabbi Yehoshua ben Chananya|Rabbi Yehoshua]] agreed with Rabbi Dosa, Rabban Gamliel felt that the still fragile post Temple destruction leadership was at risk of splintering. He decreed upon Rabbi Yehshua to come before him on Yom Kippor as it came out according to his calculations and desecrate it by carying his money and walking stick.  

Rabbi Yehshua came to Rabbi Dosa who advised him to listen to Rabban Gamliel. Since it does not mention the names of the members of [[Moshe Rabbenu|Moshe's]] Beit Din in the Torah it comes to teach us that the Beis Din of each generation is equivalent to Moshe's. Meaning; had it mentioned the members names, one could argue that any later judges were of lesser stature, however since they remain unnamed it is possible that they are equivalent. Therefore if one debates the rulings of Rabban Gamliel's Beit Din, one should debate the rulings of each Bais Din that stood since the days of Moshe. Rabbi Yehushua accepted his advice and subdued himself in front of Rabban Gamliel.
