Shabbat 137B

מל ולא פרע את המילה ⁠— כאילו לא מל.

If one circumcised but did not uncover the flesh at the area of the circumcision by folding back the thin membrane beneath the foreskin, it is as if he had not circumcised.

גמ׳ אמר רבי אבינא אמר רבי ירמיה בר אבא אמר רב: בשר החופה את רוב גובהה של עטרה.

Talmud: R' Avina said that R' Yirmeya bar Abba said that Rav said: When the Mishnah said most of the corona, they meant the flesh that covers most of the height of the corona, as well as most of its circumference.

ואם היה בעל בשר וכו׳. אמר שמואל: קטן המסורבל בבשר, רואין אותו, כל זמן שמתקשה ונראה מהול ⁠— אינו צריך למול, ואם לאו ⁠— צריך למול.

We learned in the Mishnah: If the baby was fleshy, the circumcisor corrects the circumcision so that it will not appear uncircumcised. Shmuel said: A child who is encumbered with flesh, one examines him, and as long as when his limb hardens he looks circumcised, one need not circumcise him again. And if not, meaning he does not appear circumcised even then, one must circumcise him again.

במתניתא תנא, רבן שמעון בן גמליאל אומר: קטן המסורבל בבשר, רואין אותו, כל זמן שמתקשה ואינו נראה מהול ⁠— צריך למולו, ואם לאו ⁠— אינו צריך למולו.

It was taught in a baraita that Rabban Shimon ben Gamliel says: A child who is encumbered with flesh, one examines him, and as long as when it hardens it does not appear circumcised, one needs to circumcise him again, and if not, one need not circumcise him again.

מאי בינייהו? איכא בינייהו, נראה ואינו נראה.

The Talmud asks: What is the practical difference between these two formulations? The Talmud answers: There is a practical difference between them in a case where he appears circumcised but does not appear fully circumcised. According to Shmuel, in order to avoid an additional circumcision, one must appear fully circumcised, and this state is insufficient. According to Rabban Shimon ben Gamliel, only one who appears uncircumcised requires further circumcision; this partial circumcision is adequate.
