Topic

Sterilizing remedies and סירוס; healing teeth and loins on שבת (vinegar, rose oil); רבא's retraction because of הוֹאִיל; רב's ruling like רבי שמעון.

Overview

The amud opens by finishing a question from the previous page: how may anyone drink a remedy for jaundice that causes sterility, when causing sterility (סירוס) is forbidden? The גמרא proves that sterilizing someone already sterile is still forbidden, so it rejects a סריס and then an old man, and settles on a woman. For רבי יוחנן בן ברוקא, who holds that women are also commanded in פרו ורבו, it must be an old or barren woman. Then a new משנה teaches that on שבת you may not do obvious medical treatment for aching teeth or loins, but you may act in your normal everyday way. רבי שמעון adds that all Jews count as princes, so anyone may use rose oil. The גמרא explains how vinegar can heal teeth when a פסוק says it harms them. Next it settles a clash between the משנה and a ברייתא about sipping vinegar, through the answers of אביי and רבא. It concludes that רבא retracted his own answer because of his principle of הוֹאִיל. Finally, רב rules like רבי שמעון on rose oil, and the גמרא begins a challenge from another teaching of רב that continues on the next amud.

All agree regarding one who leavens after one who leavened

שֶׁהוּא חַיָּיב,

that he is liable,

שֶׁנֶּאֱמַר: ״לֹא תֵאָפֶה חָמֵץ״,

as it is said: 'It shall not be baked leavened,'

״לֹא תֵעָשֶׂה חָמֵץ״.

'It shall not be made leavened.'
