Brit milah

Brit milah is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Brit milah rather than just read about it. In short: The brit milah (Hebrew: בְּרִית מִילָה, Modern Israeli: [bʁit miˈla], Ashkenazi: [bris ˈmilə]; "covenant of circumcision"), or bris (Yiddish: ברית, romanized: bris), is the ceremony of circumcision in Judaism and Samaritanism during which a newborn male's foreskin is surgically removed.

Key takeaways

  • Brit milah belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Brit milah to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Brit milah from memory before moving on to harder problems.

Reference excerpt

The brit milah (Hebrew: בְּרִית מִילָה, Modern Israeli: [bʁit miˈla], Ashkenazi: [bris ˈmilə]; "covenant of circumcision"), or bris (Yiddish: ברית, romanized: bris), is the ceremony of circumcision in Judaism and Samaritanism during which a newborn male's foreskin is surgically removed. According to the Book of Genesis, God commanded the biblical patriarch Abraham to be circumcised: an act to be followed by his descendants on the eighth day of life symbolizing the covenant between God and the Jewish people. Today, it is generally performed by a mohel on the eighth day after the infant's birth and is followed by a celebratory meal known as a seudat mitzvah. Brit milah is considered among the most important and central commandments in Judaism, and the rite has played a central role in Jewish history and Jewish culture. The Talmud, when discussing the importance of brit milah, considers it equal to all other mitzvot (commandments). Barring extraordinary circumstances, Abraham's descendants who voluntarily fail to undergo brit milah are believed to suffer Kareth, which is, in Jewish theology, the extinction of the soul and denial of a share in the World to Come. The brit is understood by Jews to signify acceptance into the ongoing covenant between God and the Jewish people, which is why most gerim (converts to Judaism) undergo a form of brit to finalize conversion. Historical conflicts between Jews and European civilizations have occurred several times over brit milah, including multiple campaigns of Jewish ethnic, cultural, and religious persecution, with subsequent bans and restrictions on the practice as an attempted means of forceful assimilation, most famously in the Maccabean Revolt by the Seleucid Empire. "In Jewish history, the banning of circumcision (brit milah) has historically been a first step toward more extreme and violent forms of persecution". These periods have generally been linked to suppression of Jewish religious, ethnic, and cultural identity and subsequent "punishment at the hands of government authorities for engaging in circumcision". The Maccabee victory in the Maccabean Revolt—ending the prohibition against circumcision—is celebrated in Hanukkah. Circumcision rates are near-universal among Jews, except for some heavily assimilated groups such as the Kaifeng Jews in China. Brit milah also has immense importance in other religions. The Gospel of Luke records that Mary and Joseph, the parents of Jesus, had him undergo circumcision, though the vast majority of Christians do not practice religious circumcision.

Origins (unknown to 515 BCE)

The origin of circumcision is not known with certainty; however, artistic and literary evidence from ancient Egypt suggests it was practiced in the ancient Near East from at least the Sixth Dynasty (c. 2345–2181 BCE). In the New Kingdom of Egypt (1550-1069 BCE), circumcision was "performed as a rite of passage from childhood to adulthood on boys who were going to become priests". The Bible extended the practice to the entire male population, in accord with the description of Israel as a "kingdom of priests" (Exodus 19:6). Thus, Biblical circumcision served to "detach circumcision from its age-old connection with puberty and transform it into a sign of the divine covenant and ethnic belonging". According to some scholars, it appears that it only appeared as a sign of the covenant during the Babylonian Exile. Scholars who posit the existence of a hypothetical J source (likely composed during the seventh century BCE) of the Pentateuch in Genesis 15 hold that it would not have mentioned a covenant that involves the practice of circumcision. Only in the P source (likely composed during the sixth century BCE) of Genesis 17 does the notion of circumcision become linked to a covenant. Some scholars have argued that it originated as a replacement for child sacrifice.

Worked examples

Example 1 — a first encounter with Brit milah

Start with the simplest possible case. Write down what Brit milah claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Brit milah before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Brit milah ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Brit milah

In research
Brit milah appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Brit milah in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Brit milah is common in secondary-school and first-year university syllabi. It links to neighbouring topics Childhood rites of passage, Circumcision, Hebrew words and phrases in Jewish law, so understanding it makes those chapters shorter.
In everyday life
Look for Brit milah outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
