Who Will Be Our Moral Arbiters?

(13) Next day, Moses sat as magistrate among the people, while the people stood about Moses from morning until evening. (14) But when Moses’ father-in-law saw how much he had to do for the people, he said, “What is this thing that you are doing to the people? Why do you act alone, while all the people stand about you from morning until evening?” (15) Moses replied to his father-in-law, “It is because the people come to me to inquire of God. (16) When they have a dispute, it comes before me, and I decide between one person and another, and I make known the laws and teachings of God.” (17) But Moses’ father-in-law said to him, “The thing you are doing is not right; (18) you will surely wear yourself out, and these people as well. For the task is too heavy for you; you cannot do it alone. (19) Now listen to me. I will give you counsel, and God be with you! You represent the people before God: you bring the disputes before God, (20) and enjoin upon them the laws and the teachings, and make known to them the way they are to go and the practices they are to follow. (21) You shall also seek out from among all the people capable men who fear God, trustworthy men who spurn ill-gotten gain. Set these over them as chiefs of thousands, hundreds, fifties, and tens, (22) and let them judge the people at all times. Have them bring every major dispute to you, but let them decide every minor dispute themselves. Make it easier for yourself by letting them share the burden with you.

(8) If a case is too baffling for you to decide, be it a controversy over homicide, civil law, or assault—matters of dispute in your courts—you shall promptly repair to the place that the LORD your God will have chosen, (9) and appear before the levitical priests, or the magistrate in charge at the time, and present your problem. When they have announced to you the verdict in the case, (10) you shall carry out the verdict that is announced to you from that place that the LORD chose, observing scrupulously all their instructions to you. (11) You shall act in accordance with the instructions given you and the ruling handed down to you; you must not deviate from the verdict that they announce to you either to the right or to the left. (12) Should a man act presumptuously and disregard the priest charged with serving there the LORD your God, or the magistrate, that man shall die. Thus you will sweep out evil from Israel: (13) all the people will hear and be afraid and will not act presumptuously again.

§ Rabbi Yoḥanan says: They place on the Sanhedrin only men of high stature, and of wisdom, and of pleasant appearance, and of suitable age so that they will be respected. And they must also be masters of sorcery, i.e., they know the nature of sorcery, so that they can judge sorcerers, and they must know all seventy languages in order that the Sanhedrin will not need to hear testimony from the mouth of a translator in a case where a witness speaks a different language. Rav Yehuda says that Rav says: They place on the Sanhedrin only one who knows how to render a carcass of a creeping animal pure by Torah law. The judges on the Sanhedrin must be so skilled at logical reasoning that they could even produce a convincing argument that creeping animals, which the Torah states explicitly are ritually impure, are actually pure. Rav said: I will discuss the halakha of the creeping animal and render it pure, i.e., I am able to demonstrate how it is possible to construct such a proof:
