(ו) ...... וְעוֹד אָמַר רַבִּי מַתְיָא בֶן חָרָשׁ, הַחוֹשֵׁשׁ בִּגְרוֹנוֹ, מַטִּילִין לוֹ סַם בְּתוֹךְ פִּיו בְּשַׁבָּת, מִפְּנֵי שֶׁהוּא סְפֵק נְפָשׁוֹת, וְכָל סְפֵק נְפָשׁוֹת דּוֹחֶה אֶת הַשַּׁבָּת:
........Moreover Rabbi Matia ben Harash said: if one has pain in his throat, they may drop medicine into his mouth on Shabbat, because it is a possibility of danger to human life and every potential danger to human life overrides Shabbat.
(ז) מִי שֶׁנָּפְלָה עָלָיו מַפֹּלֶת, סָפֵק הוּא שָׁם סָפֵק אֵינוֹ שָׁם, סָפֵק חַי סָפֵק מֵת, סָפֵק נָכְרִי סָפֵק יִשְׂרָאֵל, מְפַקְּחִין עָלָיו אֶת הַגַּל. מְצָאוּהוּ חַי, מְפַקְּחִין עָלָיו. וְאִם מֵת, יַנִּיחוּהוּ:
(7) If an avalanche fell on someone, and it is doubtful whether or not he is there, or whether he is alive or dead, or whether he is an Israelite or a non-Jew, they remove the debris from above him [even on Shabbat]. If they find him alive they remove the debris, but if dead they should leave him there [until Shabbat is over].
מתני׳ מי שאחזו בולמוס מאכילין אותו אפי' דברים טמאים עד שיאורו עיניו מי שנשכו כלב שוטה אין מאכילין אותו מחצר כבד שלו ור' מתיא בן חרש מתיר ועוד אמר ר' מתיא בן חרש החושש בגרונו מטילין לו סם בתוך פיו בשבת מפני שהוא ספק נפשות וכל ספק נפשות דוחה את השבת מי שנפלה עליו מפולת ספק הוא שם ספק אינו שם ספק חי ספק מת ספק כותי ספק ישראל מפקחין עליו את הגל מצאוהו חי מפקחין ואם מת יניחוהו
MISHNA: In the case of one who is seized with the life-threatening illness bulmos, causing him unbearable hunger pangs and impaired vision, one may feed him even impure foods on Yom Kippur or any other day until his eyes recover, as the return of his sight indicates that he is recovering. In the case of one whom a mad dog bit, one may not feed him from the lobe of the dog’s liver. This was thought to be a remedy for the bite, but the Rabbis deem it ineffective. And Rabbi Matya ben Ḥarash permits feeding it to him, as he deems it effective. And furthermore, Rabbi Matya ben Ḥarash said: With regard to one who suffers pain in his throat, one may place medicine inside his mouth on Shabbat, although administering a remedy is prohibited on Shabbat. This is because there is uncertainty whether or not it is a life-threatening situation for him, as it is difficult to ascertain the severity of internal pain. And a case of uncertainty concerning a life-threatening situation overrides Shabbat. Similarly, with regard to one upon whom a rockslide fell, and there is uncertainty whether he is there under the debris or whether he is not there; and there is uncertainty whether he is still alive or whether he is dead; and there is uncertainty whether the person under the debris is a gentile or whether he is a Jew, one clears the pile from atop him. One may perform any action necessary to rescue him from beneath the debris. If they found him alive after beginning to clear the debris, they continue to clear the pile until they can extricate him. And if they found him dead, they should leave him, since one may not desecrate Shabbat to preserve the dignity of the dead.
