תלמוד על שבת 269:3

“The drawn⁸⁹People originally circumcised who manipulated their penises (or had plastic surgery) to appear uncircumcised. They might have been forcibly circumcised in the general conscription ordered by Bar Kokhba. should not circumcise lest he get into danger, the words of Rebbi Jehudah. Rebbi Yose said to him, many drawn ones were in the days of Ben Koziba⁹⁰Bar Kokhba., they all circumcised, lived, and begat sons and daughters. One has to draw a drop of covenant blood from the drawn, the one born circumcised, and the circumcised convert. Rebbi Simeon ben Eleazar stated: The House of Shammai and the House of Hillel did not disagree that one has to draw a drop of covenant blood from the one born circumcised; because that is a compressed prepuce; what did they disagree about? About the convert who converted when already circumcised, for the House of Shammai said one has to draw a drop of covenant blood from him, but the House of Hillel say, one does not have to draw a drop of covenant blood from him.” Rebbi Issac bar Naḥman said in the name of Rebbi Hoshaia⁹¹Sifra Tazriaˋ Pereq 1(7); also Tosephta Šabbat 15:9; Babli Šabbat 135a; Gen. rabba 46(9).: Practice follows the words of the student⁹²R.

Jehudah., it is implied that he certainly is uncircumcised and one pushes the Sabbath away for him⁹⁶Babli Šabbat 135a. There, R. Ada bar Ahava accused himself of being punished for not following the ruling of his teacher Rav.. Rebbi Abbahu said, one does not push the Sabbath away for him but one has to draw a drop of covenant blood from him⁹⁵This is the uncontested anonymous decision of the Babli.. A son was born to Rav Ada bar Ahava in that condition⁹⁶Babli Šabbat 135a. There, R. Ada bar Ahava accused himself of being punished for not following the ruling of his teacher Rav.. He squeezed it, he died. Rebbi Abin said, testicles became injured and he fasted for him; he died. The rabbis of Caesarea said, his penis was damaged and he fasted for him; he died.
