R’ Eliezer says: If one did not bring an instrument [for circumcision] before the Sabbath, he should bring it on the Sabbath exposed; and in [times of] danger, he should cover it in the presence of witnesses. Furthermore, said R’ Eliezer: We may fell trees in order to make charcoal and to form an iron instrument. [But] R’ Akiva stated a rule: Any work that can be done before the Sabbath does not override the Sabbath; but [any work] that cannot be done before the Sab-bath does override the Sabbath.

We may perform all the necessities of circumcision on the Sabbath: we may circumcise, uncover [the corona], draw [the blood], and place a bandage and cumin upon it. If he did not crush [the cumin] before the Sabbath, he may chew [it] with his teeth and apply [it]. If he did not vigorously mix wine and oil before the Sabbath, each one should be added [to the bowl] by itself. We may not fashion a shirtlike bandage for it, but one may wrap a piece of cloth around it. If he did not prepare [it] before the Sabbath, he may wrap [it] around his finger and bring [it], even from another courtyard.

We may bathe the infant both prior to the circumcision and following the circumcision; and we may sprinkle [water] upon him by hand, but not with a utensil. R’ Elazar ben Azariah says: We may bathe the infant on the third day [following the circumcision] when it occurs on the Sabbath, as it is said: And it came to pass on the third day, when they were in pain (Genesis 34:25). A questionable one or an androgyne, we may not violate the Sabbath on his behalf. R’ Yehudah, however, permits [it] in [the case of] an androgyne.

One who had two infants, one to circumcise after the Sabbath and one to circumcise on the Sabbath, and he forgot and circumcised the one who was [to be circumcised] after the Sabbath on the Sabbath, he is liable; [if he had] one to circumcise before the Sabbath and one to circumcise on the Sabbath, and he forgot and circumcised the one who was [to be circumcised] before the Sabbath on the Sabbath, R’ Eliezer declares [him] liable for a sin offering. But R’ Yehoshua exempts [him].

An infant may be circumcised [either] on the eight, ninth, tenth, eleventh, or twelfth [day], not earlier not later. How is this? In the normal course, [he is circumcised] on the eight; if he was born at twilight, he is circumcised on the ninth; [if he was born] at twilight on the eve of the Sabbath, he is circumcised on the tenth; [if] a festival [falls] after the Sabbath, he is circumcised on the eleventh; [in the case of] the two festival days of Rosh Hashanah, he is circumcised on the twelfth. A sick infant, we may not circumcise him until he recovers.

These are the shreds that invalidate the circumcision: flesh that covers the larger part of the corona. And he may not eat of terumah. If he was fleshy, he must rectify it for appearances’ sake. If he circumcised but did not expose the circumcision, it is as if he did not circumcise.
