Gemara Final

מתני׳ ואלו הן שמצילין אותן בנפשן הרודף אחר חבירו להרגו ואחר הזכר ואחר הנערה המאורסה אבל הרודף אחר בהמה והמחלל את השבת ועובד עבודת כוכבים אין מצילין אותן בנפשן:

MISHNA: And these are the ones who are saved from transgressing even at the cost of their lives; that is to say, these people may be killed so that they do not perform a transgression: One who pursues another to kill him, or pursues a male to sodomize him, or pursues a betrothed young woman to rape her. But with regard to one who pursues an animal to sodomize it, or one who seeks to desecrate Shabbat, or one who is going to engage in idol worship, they are not saved at the cost of their lives. Rather, they are forewarned not to transgress, and if they proceed to transgress after having been forewarned, they are brought to trial, and if they are found guilty, they are executed.

גמ׳ ת"ר מניין לרודף אחר חבירו להרגו שניתן להצילו בנפשו ת"ל (ויקרא יט, טז) לא תעמוד על דם רעך והא להכי הוא דאתא האי מיבעי ליה לכדתניא מניין לרואה את חבירו שהוא טובע בנהר או חיה גוררתו או לסטין באין עליו שהוא חייב להצילו ת"ל לא תעמוד על דם רעך אין ה"נ
GEMARA: The Sages taught in a baraita: From where is it derived that with regard to one who pursues another in order to kill him, the pursued party may be saved at the cost of the pursuer’s life? The verse states: “You shall not stand idly by the blood of another” (Leviticus 19:16); rather, you must save him from death. The Gemara asks: But does this verse really come to teach us this? This verse is required for that which is taught in a baraita: From where is it derived that one who sees another drowning in a river, or being dragged away by a wild animal, or being attacked by bandits [listin], is obligated to save him? The Torah states: “You shall not stand idly by the blood of another.” The Gemara answers: Yes, it is indeed so that this verse relates to the obligation to save one whose life is in danger.
ואלא ניתן להצילו בנפשו מנלן אתיא בקל וחומר מנערה המאורסה מה נערה המאורסה שלא בא אלא לפוגמה אמרה תורה ניתן להצילה בנפשו רודף אחר חבירו להרגו על אחת כמה וכמה
The Gemara asks again: But from where do we derive that one may be saved at the cost of the pursuer’s life? The Gemara answers: It is derived by means of an a fortiori inference from the halakha governing a betrothed young woman who was assaulted by a rapist: If in the case of a betrothed young woman, whom the rapist comes only to degrade, i.e., the result of the rape will be that her status is lowered, the Torah said that she may be saved even at the cost of the rapist’s life, then in the case of one who pursues another person to kill him, all the more so should one say that he may be saved even at the cost of the pursuer’s life.
וכי עונשין מן הדין דבי רבי תנא הקישא הוא (דברים כב, כו) כי כאשר יקום איש על רעהו ורצחו נפש וכי מה למדנו מרוצח
The Gemara asks: But does the court administer punishment based on an a fortiori inference? The Gemara answers: A Sage of the school of Rabbi Yehuda HaNasi taught: This halakha is also derived from an analogy based on a juxtaposition. How so? With regard to the rape of a betrothed young woman it is written: “But you shall do nothing to the young woman; the young woman has committed no sin worthy of death; for as when a man rises against his neighbor, and slays him, so too with this matter” (Deuteronomy 22:26). But why would the verse mention murder in this context? But what do we learn here from a murderer?
מעתה הרי זה בא ללמד ונמצא למד מקיש רוצח לנערה המאורסה מה נערה המאורסה ניתן להצילה בנפשו אף רוצח ניתן להצילו בנפשו
Now, the mention of murder came in order to teach a halakha about the betrothed young woman, and it turns out that, in addition, it derives a halakha from that case. The Torah juxtaposes the case of a murderer to the case of a betrothed young woman to indicate that just as in the case of a betrothed young woman one may save her at the cost of the rapist’s life, so too, in the case of a murderer, one may save the potential victim at the cost of the murderer’s life.
ונערה מאורסה גופה מנלן כדתנא דבי ר' ישמעאל דתנא דבי רבי ישמעאל (דברים כב, כז) ואין מושיע לה הא יש מושיע לה בכל דבר שיכול להושיע
The Gemara asks: And with regard to the betrothed young woman herself, from where do we derive that she may be saved at the cost of the rapist’s life? The Gemara explains: As it was taught in the school of Rabbi Yishmael: The verse states: “For he found her in the field, and the betrothed young woman cried out, and there was none to save her” (Deuteronomy 22:27). But if there was someone to save her, he must do so by any means that can save her, even by killing the potential rapist.
גופא מניין לרואה את חברו שהוא טובע בנהר או חיה גוררתו או לסטין באין עליו שהוא חייב להצילו ת"ל לא תעמוד על דם רעך והא מהכא נפקא מהתם נפקא אבדת גופו מניין ת"ל והשבותו לו
Concerning the matter itself, it is taught in a baraita: From where is it derived that one who sees another drowning in a river, or being dragged away by a wild animal, or being attacked by bandits, is obligated to save him? The verse states: “You shall not stand idly by the blood of another” (Leviticus 19:16). The Gemara asks about this derivation: But is this really derived from here? It is derived from there, i.e., from a different verse, as it is taught: The Torah teaches that one must return lost property to its rightful owner. But from where is it derived that one must help his neighbor who may suffer the loss of his body or his health? The verse states: “And you shall restore it [vahashevato] to him [lo]” (Deuteronomy 22:2), which can also be read as: And you shall restore him [vehashevato] to him, i.e., saving his body. Consequently, there should be no need for the additional verse: “You shall not stand idly by the blood of another.”
אי מהתם הוה אמינא ה"מ בנפשיה אבל מיטרח ומיגר אגורי אימא לא קמ"ל
The Gemara answers: If this halakha were derived only from there, I would say that this matter applies only to saving the person in danger by himself, i.e., that he himself must come to his neighbor’s rescue if he can, as is the halakha with regard to returning a lost item. But to trouble himself and hire workers for this purpose, one might say that he is not obligated, just as he is not obligated to hire workers to recover another’s lost item. Therefore, the verse “Do not stand by the blood of another” teaches us that he must even hire workers, and he transgresses a prohibition if he does not do so.
כָּל הַיָּכוֹל לְהַצִּיל וְלֹא הִצִּיל עוֹבֵר עַל (ויקרא יט טז) "לֹא תַעֲמֹד עַל דַּם רֵעֶךָ". וְכֵן הָרוֹאֶה אֶת חֲבֵרוֹ טוֹבֵעַ בַּיָּם. אוֹ לִסְטִים בָּאִים עָלָיו. אוֹ חַיָּה רָעָה בָּאָה עָלָיו. וְיָכוֹל לְהַצִּילוֹ הוּא בְּעַצְמוֹ. אוֹ שֶׁיִּשְׂכֹּר אֲחֵרִים לְהַצִּילוֹ וְלֹא הִצִּיל. אוֹ שֶׁשָּׁמַע עוֹבְדֵי כּוֹכָבִים אוֹ מוֹסְרִים מְחַשְּׁבִים עָלָיו רָעָה אוֹ טוֹמְנִין לוֹ פַּח וְלֹא גִּלָּה אֹזֶן חֲבֵרוֹ וְהוֹדִיעוֹ. אוֹ שֶׁיָּדַע בְּעַכּוּ''ם אוֹ בְּאוֹנֵס שֶׁהוּא בָּא עַל חֲבֵרוֹ וְיָכוֹל לְפַיְּסוֹ בִּגְלַל חֲבֵרוֹ לְהָסִיר מַה שֶּׁבְּלִבּוֹ וְלֹא פִּיְּסוֹ. וְכָל כַּיּוֹצֵא בִּדְבָרִים אֵלּוּ. הָעוֹשֶׂה אוֹתָם עוֹבֵר עַל לֹא תַעֲמֹד עַל דַּם רֵעֶךָ:
Whenever a person can save another person's life, but he fails to do so, he transgresses a negative commandment, as Leviticus 19:16 states: "Do not stand idly by while your brother's blood is at stake."
Similarly, this commandment applies when a person sees a colleague drowning at sea or being attacked by robbers or a wild animal, and he can save him himself or can hire others to save him. Similarly, it applies when he hears gentiles or mosrim conspiring to harm a colleague or planning a snare for him, and he does not inform him and notify him of the danger.
And it applies when a person knows of a gentile or a man of force who has a complaint against a colleague, and he can appease the aggressor on behalf of his colleague, but he fails to do so. And similarly, in all analogous instances, a person who fails to act transgresses the commandment: "Do not stand idly by while your brother's blood is at stake."

מתני' ואלו שמצילין אותן - מן העבירה:

and those who save them - from the offense...

מה נערה המאורסה ניתן להצילה - מן העבירה בנפשו אף רוצח וכו' ואכתי ילפא נערה מרוצח שתהרג ואל תעבור כדלקמן ומיהו הכא לא אסיקנא במילתיה דר' דאגב גררא אתיא:

What girl who is betrothed can be saved - from the crime in his soul, even a murderer, etc. And my sister will heal a girl from a murderer who is killed and do not pass as follows and who is this I will not envy the words of Dr. Dagg Garra Atia:...

וְהוּא הַדִּין לִשְׁאָר כָּל הָעֲרָיוֹת חוּץ מִן הַבְּהֵמָה. אֲבָל הַזָּכוּר מַצִּילִין אוֹתוֹ בְּנֶפֶשׁ הָרוֹדֵף כִּשְׁאָר כָּל הָעֲרָיוֹת. אֲבָל הָרוֹדֵף אַחַר הַבְּהֵמָה לְרָבְעָהּ. אוֹ שֶׁרָדַף לַעֲשׂוֹת מְלָאכָה בְּשַׁבָּת אוֹ לַעֲבֹד עֲבוֹדָה זָרָה. אַף עַל פִּי שֶׁהַשַּׁבָּת וַעֲבוֹדָה זָרָה עִקְּרֵי הַדָּת אֵין מְמִיתִין אוֹתוֹ עַד שֶׁיַּעֲשֶׂה וִיבִיאוּהוּ לְבֵית דִּין וִידִינוּהוּ וְיָמוּת:
The same laws apply with regard to any woman forbidden as an ervah, but not to relations with an animal. With regard to homosexual rape, by contrast, one may save a man from being raped by killing the intended rapist.
If one pursues an animal with the intent of sodomizing it, or one seeks to perform a forbidden labor on the Sabbath or to worship idols - although the Sabbath and the prohibition against idol worship are fundamental elements of our faith - the person should not be killed until he commits the transgression and is brought to court, convicted and executed.
