פרקי אבות שיעור שישי א ו-ח

(6) Joshua ben Perahiah and Nittai the Arbelite received [the oral tradition] from them. Joshua ben Perahiah used to say: appoint for thyself a teacher, and acquire for thyself a companion and judge all men with the scale weighted in his favor.

(7) Nittai the Arbelite used to say: keep a distance from an evil neighbor, do not become attached to the wicked, and do not abandon faith in [divine] retribution.

(8) Judah ben Tabbai and Shimon ben Shetach received [the oral tradition] from them. Judah ben Tabbai said: do not [as a judge] play the part of an advocate; and when the litigants are standing before you, look upon them as if they were [both] guilty; and when they leave your presence, look upon them as if they were [both] innocent, when they have accepted the judgement.

The Gemara asks: But what is the reason that others do not judge the kings of Israel? It is because of an incident that happened, as the slave of Yannai the king killed a person. Shimon ben Shataḥ said to the Sages: Put your eyes on him and let us judge him. They sent word to Yannai: Your slave killed a person. Yannai sent the slave to them. They sent word to Yannai: You also come here, as the verse states with regard to an ox that gored a person to death: “He should be testified against with his owner” (Exodus 21:29). The Torah stated: The owner of the ox should come and stand over his ox. The Gemara continues to narrate the incident: Yannai came and sat down. Shimon ben Shataḥ said to him: Yannai the king, stand on your feet and witnesses will testify against you. And it is not before us that you are standing, to give us honor, but it is before the One Who spoke and the world came into being that you are standing, as it is stated: “Then both the people, between whom the controversy is, shall stand before the Lord, before the priests and the judges that shall be in those days” (Deuteronomy 19:17). Yannai the king said to him: I will not stand when you alone say this to me, but according to what your colleagues say, and if the whole court tells me, I will stand. Shimon ben Shataḥ turned to his right. The judges forced their faces to the ground out of fear and said nothing. He turned to his left, and they forced their faces to the ground and said nothing. Shimon ben Shataḥ said to them: You are masters of thoughts, enjoying your private thoughts, and not speaking. May the Master of thoughts, God, come and punish you. Immediately, the angel Gabriel came and struck those judges to the ground, and they died. At that moment, when they saw that the Sanhedrin does not have power to force the king to heed its instructions, the Sages said: A king does not judge others and others do not judge him, and he does not testify and others do not testify concerning him, due to the danger of the matter. The mishna teaches that the king does not perform ḥalitza with his brother’s widow and his brother does not perform ḥalitza with his wife, and Rabbi Yehuda says that he may do so if he wishes. The Gemara challenges Rabbi Yehuda’s opinion: Is that so? But doesn’t Rav Ashi say: Even according to the one who says that with regard to a Nasi who relinquished the honor due him, his honor is relinquished, nevertheless, with regard to a king who relinquished the honor due him, his honor is not relinquished, as it is stated: “You shall set a king over you” (Deuteronomy 17:15), meaning that his fear should be upon you. The preservation of a king’s honor is mandated by the Torah. How could Rabbi Yehuda allow him to waive it? The Gemara answers: A mitzva is different; a king is not disgraced if he relinquishes his honor to perform a mitzva.

One of the central functions of the ketuavh is to prevent unnecessary divorces. Since, as a result of an angry husband remembering the amount he would have to pay to his wife if he divorces her, he calms down and thinks, "Perhaps it would be better to live with her peacefully and lovingly rather than having to pay for her ketuvah." It is as the Sages said (Ketuvot 39b), "So that it not be easy in his eyes to cast her out." In order to ensure the wife's rights, Rabbi Shimon ben Shetach ordained that all of the husband's property be liable for the payment of the ketuvah. That is that even if the husband does not have cash at the time of the divorce, all of his properties are frozen, such that the value of the ketuvah is paid from there. This decree as well is aimed at preventing angry husbands from hastily divorcing.
