Circumcision has long been understood as the “completion” of man and as essential to man`s entry into the covenant, community, and world to come. Rabbinic Judaism regarded the Brit Milah (Circumcision Covenant) and the ceremony that accompanied it as a joyful occasion, and the sages considered it important to circumcise converts and slaves as well. Some rabbinic Midrash claim that a number of biblical heroes were born circumcised (ARN1 2). Rabbinic explanations of circumcision do not deal with the philosophical and medical justifications claimed by later sources, but with the sanctification of a divine commandment. Traditionally, Brit Milah takes place on the eighth day of the baby`s life, even if it falls on Shabbat or a Jewish holiday. However, if medical problems bother, the breakage is postponed until the baby is considered healthy enough. In this case, the breakage is scheduled for an hour that is not Shabbat or a holiday.

Circumcision dates back to the book of Genesis, when God commands Abraham to circumcise himself and his descendants as a sign of the covenant between the Jews and God.
Throughout history, rabbis and thinkers have made additional arguments in favor of circumcision, and many modern Jews see it as an important tradition that connects generations. An esteemed Jewish legend says that the prophet Elijah is present at every b`laugh milah. Elijah, most often considered the forerunner of the Messianic age, is also often referred to as the “angel of the covenant” (Malachi 3:1), the protector of young children—in fact, a “guardian angel.” So the Jews reserved a special chair for Elijah on the b`laugh, with the baby placed on the chair before the circumcision. A milah l`shem giur is a “circumcision for the purpose of conversion”. In Orthodox Judaism, this procedure is usually performed by adoptive parents for adopted boys who are converted as part of the adoption, or by families with young children who convert together. It is also required for adult converts who have not yet been circumcised, such as those born in countries where circumcision at birth is not common. The conversion of a minor applies in Orthodox and Conservative Judaism until a child reaches the age of majority (13 for a boy, 12 for a girl); At that time, the child has the opportunity to renounce his conversion and Judaism, and the conversion is then retroactively considered invalid. He must be informed of his right to renounce his conversion if he so wishes. If he does not make such a statement, it is admitted that the boy is halakhically Jewish. Orthodox rabbis will generally not convert a non-Jewish child raised by a mother who has not converted to Judaism.  Circumcision is the removal of the foreskin of the penis. The rite of circumcision (brit milah) is one of the oldest practices of Judaism.
The commandment to circumcise male children was given to Abraham in the Torah (Genesis 17:714 and repeated in Leviticus 12:3): The father (or both parents [if the mother desires it and the mohel is pleasant]) should give the knife to the mohel and help him perform the milah to indicate that the mohel is the agent of the parents. [If the child`s father is not Jewish, then traditionally the mohel simply acts on behalf of the church.] B`rit milah is the oldest religious rite in Judaism, dating back nearly four thousand years. It is first mentioned in Genesis 17 when God commands Abraham: “Every man among you shall be circumcised. You must prune the flesh of your foreskin, and this will be the sign of the covenant between Me and you. At the age of eight days, every man among you will be circumcised over generations, even the slave born in the house. An uncircumcised man. broke my alliance. According to the Torah, Abraham immediately followed God`s commandment and circumcised himself, his son Ishmael, and all the men in his household.
Abraham was ninety-nine years old at the time of his circumcision, while Ishmael was thirteen, which could serve in part to explain the common practice among some peoples of circumcision at puberty. From then on, however, Jewish men were circumcised at the age of eight, not as a symbol of fertility, but as a sign of their belonging to a covenant people. A British Milah is more than a circumcision; it is a sacred ritual in Judaism that is different from its non-ritual requirement in Islam. One effect is that the Briton is not considered complete unless a drop of blood is actually taken. Standard medical methods of circumcision by constriction do not meet the requirements of halakha for Brit Milah, since they are performed with hemostasis, that is, they stop blood flow. In addition, circumcision alone in the absence of the Brit Milah ceremony does not meet the requirements of the mitzvah. Therefore, in cases where a Jew who has been circumcised outside a British milah, concerns an already circumcised convert or an aposthetic (born without a foreskin), the mohel draws a symbolic drop of blood (Hebrew: הטפת דם, mother Hatafat) from the penis where the foreskin would have been or was tied.  A Mohel is a Jew who is trained in the practice of Brit Milah, the “League of Circumcision.” Under traditional Jewish law, in the absence of a free adult Jewish male expert, anyone with the necessary skills also has the right to perform circumcision if they are Jewish.   Nevertheless, most currents of non-Orthodox Judaism allow female mohels, called Mohalot (Hebrew: מוֹהֲלוֹת, plural of מוֹהֶלֶת mohelet, wife of mohel), without restriction. In 1984, Deborah Cohen became the first certified reform mohelet; it was certified by the Berit Mila program of Reform Judaism.
 Whenever possible, the British should take place with a minyan (a quorum of 10 people [in traditional communities 10 men]). According to Jewish tradition, it is the duty of a parent to circumcise a son and offer the child a triple blessing: a life enriched by the Torah, the canopy of marriage (chuppah) and good deeds. Today, a mohel or mohelet is regularly designated by parents to fulfill this custom. Removal of the foreskin and bloodshed combine ancient apotropaic motivations to prevent disease and promote health by keeping demons away. The mystical and magical reasons for circumcision may also have helped to believe that the blood of circumcision is strong and atoning. In Exodus 4:25, it is the blood of circumcision that saves Moses` life when Zipporah circumcises the son of Moses (or perhaps Moses himself). The creation of a collective tribal brotherhood based on circumcision ensured the continuity of the patriarchal lineage and acculturated the little boy to masculinity, while publicly diminishing the female birth role. Some have seen the depiction of circumcision as a male empowerment ritual that phallically binds men to the ministry of a deity that functions through men and their bodies, not only in reproductive activity, but also as a source of cultural and intellectual creativity. In Jewish mysticism, Zohar implies that only a circumcised person can fully communicate with God or see Him. Several central Kabbalistic concepts are based on interpretations of the meanings of circumcision.
These include the “inscription” of God`s name in the flesh and contemplation of the divine presence or connection to *Shekhinah through the physical Berit Milah. Family physicians may also be asked to perform circumcision. The doctor, if used, must be Jewish and may be accompanied by the head of the religious ceremony of b`rit milah, whether it is a rabbi or a relative. Many Brit Milah ceremonies also include other readings and blessings, and parents often talk about why they chose the boy`s Hebrew name. The ceremony is usually followed by a festive meal, and special prayers are recited in grace after the meal to bless the parents, infant, mohel and sandek.
