Deuteronomy 16:18

Magistrates, ( magistros,) "masters;" people learned in the law, who may assist the judges with their counsel in any emergency. Hebrew shotrim, "officers, heralds, lictors," &c., chap. i. 15. (Haydock) --- Bonfrere (in Exodus xviii. 25,) thinks that these were the judges set over each tribe, or else the assessors of the judges. (Menochius) --- The Rabbins mention three tribunals of the Jews: 1. The Sanhedrim, consisting of seventy judges, with a prince at the head of them; 2. the twenty-three judges, who resided in considerable cities; 3. the tribunal of three judges, who administered justice in the villages, which had not above 120 inhabitants. But Josephus ([Antiquities?] iv. last chapter.) only mentions, that Moses established in each city seven judges, who had each two officers of the tribe of Levi. --- Gates, where the judges sat.
