(32) Once, when the Israelites were in the wilderness, they came upon a man gathering wood on the sabbath day. (33) Those who found him as he was gathering wood brought him before Moses, Aaron, and the whole community. (34) He was placed in custody, for it had not been specified what should be done to him. (35) Then the LORD said to Moses, “The man shall be put to death: the whole community shall pelt him with stones outside the camp.” (36) So the whole community took him outside the camp and stoned him to death—as the LORD had commanded Moses. (among 34 other examples in the Chumash)
(קו) וְעַל חֲטָאִים שֶׁאָֽנוּ חַיָּבִים עֲלֵיהֶם אַרְבַּע מִיתוֹת בֵּית דִּין. סְקִילָה. שְׂרֵפָה. הֶֽרֶג. וְחֶֽנֶק.
(106) And for sins for which we are liable to any of the four death penalties inflicted by the [Rabbinic] Court [which are]: stoning, burning, beheading or strangulation.
(ד) דִּינֵי נְפָשׁוֹת, בְּעֶשְׂרִים וּשְׁלֹשָׁה. הָרוֹבֵעַ וְהַנִּרְבָּע, בְּעֶשְׂרִים וּשְׁלֹשָׁה, שֶׁנֶאֱמַר (ויקרא כ) וְהָרַגְתָּ אֶת הָאִשָּׁה וְאֶת הַבְּהֵמָה, וְאוֹמֵר (שם) וְאֶת הַבְּהֵמָה תַּהֲרֹגוּ. שׁוֹר הַנִּסְקָל, בְּעֶשְׂרִים וּשְׁלֹשָׁה, שֶׁנֶּאֱמַר (שמות כא) הַשּׁוֹר יִסָּקֵל וְגַם בְּעָלָיו יוּמָת, כְּמִיתַת בְּעָלִים כָּךְ מִיתַת הַשּׁוֹר. הַזְּאֵב וְהָאֲרִי, הַדֹּב וְהַנָּמֵר וְהַבַּרְדְּלָס וְהַנָּחָשׁ, מִיתָתָן בְּעֶשְׂרִים וּשְׁלֹשָׁה. רַבִּי אֱלִיעֶזֶר אוֹמֵר, כָּל הַקּוֹדֵם לְהָרְגָן, זָכָה. רַבִּי עֲקִיבָא אוֹמֵר, מִיתָתָן בְּעֶשְׂרִים וּשְׁלֹשָׁה:
(4) Cases of capital law are judged by twenty-three judges. An animal that copulated with a person and an animal that was the object of bestiality are judged by twenty-three judges, as it is stated: “And if a woman approaches any animal to lie with it, you shall kill the woman and the animal” (Leviticus 20:16), and it states: “And if a man lies with an animal, he shall be put to death and you shall kill the animal” (Leviticus 20:15). In cases of bestiality, the verse juxtaposes the execution of the animal to the execution of the person, and therefore the case of the animal is adjudicated in the same way as cases of capital law. Similarly, an ox that is to be stoned because it killed a person is judged by twenty-three judges, as it is stated: “But if the ox was wont to gore in time past, and warning has been given to its owner, but he did not guard it and it kills a man or a woman the ox shall be stoned and also its owner shall be put to death” (Exodus 21:29). From this verse it is derived that just as the manner of the death of the owner, so is the manner of the death of the ox. The same halakha applies in the case of a wolf or a lion, a bear or a leopard, or a cheetah, or a snake that killed a person: Their death is decreed by twenty-three judges. Rabbi Eliezer says these dangerous animals do not need to be brought to court; rather, anyone who kills them first merits the performance of a mitzva. Rabbi Akiva says: Their death is decreed by twenty-three judges.
(י) מִי שֶׁנִּגְמַר דִּינוֹ וּבָרַח וּבָא לִפְנֵי אוֹתוֹ בֵית דִּין, אֵין סוֹתְרִים אֶת דִּינוֹ. כָּל מָקוֹם שֶׁיַּעַמְדוּ שְׁנַיִם וְיֹאמְרוּ, מְעִידִין אָנוּ בְאִישׁ פְּלוֹנִי שֶׁנִּגְמַר דִּינוֹ בְּבֵית דִּינוֹ שֶׁל פְּלוֹנִי, וּפְלוֹנִי וּפְלוֹנִי עֵדָיו, הֲרֵי זֶה יֵהָרֵג. סַנְהֶדְרִין נוֹהֶגֶת בָּאָרֶץ וּבְחוּצָה לָאָרֶץ. סַנְהֶדְרִין הַהוֹרֶגֶת אֶחָד בְּשָׁבוּעַ נִקְרֵאת חָבְלָנִית. רַבִּי אֶלְעָזָר בֶּן עֲזַרְיָה אוֹמֵר, אֶחָד לְשִׁבְעִים שָׁנָה. רַבִּי טַרְפוֹן וְרַבִּי עֲקִיבָא אוֹמְרִים, אִלּוּ הָיִינוּ בַסַּנְהֶדְרִין לֹא נֶהֱרַג אָדָם מֵעוֹלָם. רַבָּן שִׁמְעוֹן בֶּן גַּמְלִיאֵל אוֹמֵר, אַף הֵן מַרְבִּין שׁוֹפְכֵי דָמִים בְּיִשְׂרָאֵל:
Concerning one whose verdict was delivered and he was sentenced to death and he fled, and he then came before the same court that sentenced him, they do not overturn his verdict and retry him. Rather, the court administers the previous verdict. Consequently, in any place where two witnesses will stand and say: We testify with regard to a man called so-and-so that his verdict was delivered and he was sentenced to death in the court of so-and-so, and so-and-so and so-and-so were his witnesses, that person shall be executed on the basis of that testimony. The mishna continues: The mitzva to establish a Sanhedrin with the authority to administer capital punishments is in effect both in Eretz Yisrael and outside Eretz Yisrael. A Sanhedrin that executes a transgressor once in seven years is characterized as a destructive tribunal. Since the Sanhedrin would subject the testimony to exacting scrutiny, it was extremely rare for a defendant to be executed. Rabbi Elazar ben Azarya says: This categorization applies to a Sanhedrin that executes a transgressor once in seventy years. Rabbi Tarfon and Rabbi Akiva say: If we had been members of the Sanhedrin, we would have conducted trials in a manner whereby no person would have ever been executed. Rabban Shimon ben Gamliel says: In adopting that approach, they too would increase the number of murderers among the Jewish people. The death penalty would lose its deterrent value, as all potential murderers would know that no one is ever executed.
(קד) וְעַל חֲטָאִים שֶׁאָֽנוּ חַיָּבִים עֲלֵיהֶם מִיתָה בִּידֵי שָׁמָֽיִם:
(104) And for sins for which we incur the penalty of death at the hand of Heaven.
רבי נחוניא בן הקנה דתניא רבי נחוניא בן הקנה היה עושה את יום הכפורים כשבת לתשלומין מה שבת מתחייב בנפשו ופטור מן התשלומין אף יום הכפורים מתחייב בנפשו ופטור מן התשלומין מ"ט דר' נחוניא בן הקנה אמר אביי נאמר (שמות כא, כג) אסון בידי אדם ונאמר (בראשית מב, לח) אסון בידי שמים מה אסון האמור בידי אדם פטור מן התשלומין אף אסון האמור בידי שמים פטור מן התשלומין
Rabbi Neḥunya ben HaKana, as it is taught in a baraita: Rabbi Neḥunya ben HaKana would render Yom Kippur like Shabbat with regard to payment for damages. Just as one who intentionally desecrates Shabbat is liable to receive the death penalty and is therefore exempt from the obligation of payment for damages caused while desecrating Shabbat, so too, one who intentionally desecrates Yom Kippur is liable to receive the death penalty and is therefore exempt from the obligation of payment for damages caused while desecrating Yom Kippur. The Gemara asks: What is the rationale for the opinion of Rabbi Neḥunya ben HaKana? Abaye said: It states the word harm at the hands of man, in the verse “But if any harm follow, then you shall give a soul for a soul” (Exodus 21:23) and it states the word harm at the hand of Heaven, in the verse in which Jacob states: “My son shall not descend with you…and harm befalls him on the way” (Genesis 42:38). Just as with regard to harm that is stated at the hands of man, e.g., one who kills and is liable to be executed, one is exempt from the associated payment, so too, with regard to harm that is stated at the hand of Heaven, one is exempt from the associated payment.
