שבת י״ט:ה׳ - י״ט:ו׳

If he was born during twilight, he is circumcised on the ninth day as it is the eighth day from the morrow; if twighlight is still considered day, he is thus circumcised on the ninth day. If the day (preceding the twighlight during which he was born) is Friday, he can't be circumcised on the following Shabbat in case it is the ninth day and it is a postponed circumcision which does not supersede Shabbat, he must wait until after Shabbat and be circumcised on the tenth day.

חל יום טוב להיות אחר השבת – no circumcision which is [not performed] at its [appropriate] time may supersede it, and he is circumcised on the eleventh day [after his birth].

שני ימים טובים של ראש השנה – for they are one level of sanctity and a circumcision [performed] not at its appropriate time does not supersede the Festival observance of the Second Day of Rosh Hashanah; he is circumcised on the twelfth day [from the day of his birth].

עד שיבריא – and seven complete days in astronomical hours should pass from the day that he is healed, and afterwards, we circumcise him (i.e., the child).

ציצין –hidden shreds of flesh that remain from the foreskin.

עטרה – it is a tall rim which surrounds the membrum virile round about and from it slants and descends to its head and the skin that covers most of the corona of the membrum virile as our Mishnah teaches , one should not say most of the coagulation, but even most of its height in one location.

אינו אוכל בתרומה – if he is a Kohen, for an uncircumcised Kohen is prohibited to eat the priest’s due/Terumah. It is said regarding the Passover sacrifice (Exodus 12:45): “No bound or hired laborer shall eat of it,” and it is stated regarding Terumah (Leviticus 22:10): “No bound or hired laborer of a priest shall eat of the sacred donations.” Just as the Passover offering is prohibited to someone uncircumcised, so too the Terumah is prohibited to someone uncircumcised.

ואם היה בעל בשר – if he was fat and flesh appeared that was above his uncircumcised membrum, after the foreskin was taken off completely, as if the flesh returned and covered the membrum virile.

מתקנו – and he slants the cutting utensil/knife from that thickness [of the fat].

מפני מראית העין – so that he would not appear as uncircumcised.

ולא פרע – and he did not reveal it.

כאלו לא מל – and he would go back and split the membrane and pull it down and even if he removed his hand from it – for all the while that he is engaged in the circumcision on the Sabbath, he cuts whether the remaining shreds invalidate the act by omission or whether they don’t invalidate the act by omission after he removes his hand from the shreds which invalidate the act, he returns to the shreds which do not invalidate the act and he doesn’t go back.
