תלמוד על סוטה 1:4

HALAKHAH: “Two robbery judges were in Jerusalem,” etc. Did not Rebbi Phineas say in the name of Rebbi Hoshaia: 469 synagogues were in Jerusalem and each one of them had a Book house and a study house; the Book house for Scripture and the study house for Mishnah⁶Since every “study house” was a law school, it is obvious that Jerusalem had more than two judges.
The statement of R. Phineas is also in Megillah 3:1 (73d 28), Thr. rabbati 2:2, Introduction #12; in Ta‘anit 4, (69a 13) the number of schools is put at 500 in the name of Rabban Simeon ben Gamliel. In the Babli, 105a, the number is 394.? But these two were appointed for robberies; to teach you that if anybody has the power to intervene, if he does not exercise his power the misconduct is attributed to him⁷The other judges were for civil cases. Those appointed to watch over public order are personally held responsible; therefore these judges are remembered by name. In the Babli, 105a, it is asserted that judges in a criminal court can be paid, in contrast to civil judges.. It was stated in the name of Rebbi Nathan: Naḥum the Mede also was with them⁸In the Babli, 105a, this tradition is denied.. In Rebbi Nathan’s opinion, three robbery judges were in Jerusalem.
