Shabbat

but [of] one in doubt does not supersede the Sabbath; 'his foreskin' [of] one who is certain supersedes the Sabbath, but an hermaphrodite does not supersede the Sabbath. R. Judah maintained: An hermaphrodite supersedes the Sabbath and there is the penalty of kareth. 'His foreskin': [of] one who is certain supersedes the Sabbath, but [of] one born at twilight  does not supersede the Sabbath; his foreskin: one who is certain supersedes the Sabbath, but one who is born circumcised does not supersede the Sabbath, for Beth Shammai maintain: One must cause a few drops of the covenant blood to flow from him, while Beth Hillel rule: It is unnecessary. R. Simeon b. Eleazar said: Beth Shammai and Beth Hillel did not differ concerning him who is born circumcised that you must cause a few drops of the covenant blood to flow from him, because it is a suppressed foreskin:  about what do they differ? about a proselyte who was converted when [already] circumcised: there Beth Shammai maintain: One must cause a few drops of the covenant blood to flow from him; whereas Beth Hillel rule: One need not cause a few drops of the covenant blood to flow from him. The Master said: 'But [of] one that is doubtful does not supersede the Sabbath.' What does this include?  — It includes the following which was taught by our Rabbis: For a seven-months' infant  one may desecrate the Sabbath, but for an eight-months' infant one may not desecrate the Sabbath.  For one in doubt whether the is a seven-months' or an eight-months' infant, one may not desecrate the Sabbath. An eight-months' infant is like a stone and may not be handled, but his mother bends [over] and suckles him because of the danger. It was stated: Rab said: The halachah is as the first Tanna;  while Samuel said: The halachah is as R. Simeon b. Eleazar. A circumcised child was born to R. Adda b. Ahabah. He took him to thirteen circumcisers,  until he mutilated him privily.  I deserve it for transgressing Rab's [ruling], said he. Said R. Nahman to him, And did you not violate Samuel's [ruling]? Samuel ruled this only of weekdays, but did he rule this of the Sabbath? — He [R. Adda b. Ahabah] held that it is definitely a suppressed foreskin.  For it was stated: Rabbah said: We suspect that it may be a suppressed foreskin;  R. Joseph said: It is certainly a suppressed foreskin. R. Joseph said: Whence do I know it? Because it was taught, R. Eliezer ha-Kappar said: Beth Shammai and Beth Hillel do not disagree concerning him who is born circumcised, that one must cause a few drops of the covenant blood to flow from him. Concerning what do they differ? As to whether the Sabbath is desecrated on his account: Beth Shammai maintain, We desecrate the Sabbath on his account; while Beth Hillel rule: We must not desecrate the Sabbath on his account. Does it then not follow that the first Tanna holds, We desecrate the Sabbath for him?  But perhaps the first Tanna maintains that all agree that we may not desecrate the Sabbath for him? — If so, R. Eliezer ha-Kappar comes to teach us Beth Shammai's view!  But perhaps he means this: Beth Shammai and Beth Hillel did not disagree in this matter!  R. Assi said: He whose mother is defiled through confinement must be circumcised at eight [days], but he whose mother is not defiled through confinement  is not circumcised on the eighth day,  because it is said, If a woman conceive seed, and bear a man child, then she shall be unclean, etc. … And in the eighth day the flesh of his foreskin shall be circumcised.  Said Abaye to him, Let the early generations  prove [the reverse], where the mother was not defiled through confinement,  yet circumcision was of the eighth day!  — The Torah was given, replied he,
