Around 140 CE Rabbinic Judaism made its circumcision requirements stricter. Jewish circumcision includes the removal of the inner preputial epithelium, in a procedure that is called "priah"(Hebrew: פריעה), which means: 'uncovering'. This epithelium is also removed on modern medical circumcisions, to prevent post operative penile adhesion and its complications. According to rabbinic interpretation of the traditional Jewish sources, the "periah" has been performed, as part of Jewish circumcision, since the Israelites first inhabited the Land of Israel, and without it the mitzvah isn't performed at all.
