Judaism is among the world’s oldest surviving religious traditions, but it cannot be understood simply by asking what Jews believe about God. Its sacred stories describe a covenant between God and a people; its scriptures contain law, poetry, prophecy, history, and argument; and its practices have been shaped by centuries of life in different parts of the world. A Jewish person may be deeply observant, religiously liberal, secular, or uncertain about faith, yet still find meaning in a shared inheritance.
Judaism also helped shape the religious world in which Christianity and Islam emerged, although it is not merely a precursor to either. Its central ideas have developed within an ongoing conversation between ancient texts and successive generations. To understand Judaism, we need to follow that conversation: from Abraham and Moses to the Temple, the rabbis, the many Jewish communities, and the rhythms of ordinary life.
The Covenant: Abraham, Jacob, Moses, and Sinai
The Torah, Judaism’s foundational scripture, begins on the grandest possible scale: God creates the heavens and the earth, orders a world out of chaos, and rests on the seventh day. That final act establishes a pattern that will later shape Jewish time itself. The creation story is not merely an explanation of beginnings; it introduces a world with purpose, moral significance, and a recurring space for rest.
The narrative then narrows from all humanity to one family. In the book of Genesis, God calls Abram, later named Abraham, to leave his homeland in Mesopotamia and travel to Canaan, a region along the eastern Mediterranean. God promises that Abraham’s descendants will become a great people and establishes a covenant with them. This is not presented as a casual bargain between equals, but as an enduring relationship involving divine promises and human obligations.
Circumcision becomes a physical sign of that covenant for Abraham and the males of his household. In Jewish tradition, brit milah, the covenant of circumcision, remains a significant ceremony, customarily performed on a boy’s eighth day when medically appropriate. The striking feature of the biblical account is that belonging to the covenant is expressed not only through belief but through a practice carried from one generation to the next. Religious identity becomes something lived in the body, family, and community.
Abraham’s grandson Jacob adds a different dimension to this relationship. Genesis tells of a mysterious nighttime struggle in which Jacob wrestles with a figure understood in different interpretations as a divine being, an angel, or a man. After the encounter, he receives the name Israel, often associated with striving or struggling with God. The story gives a memorable image to an important theme in Jewish life: faith can include questioning, argument, difficulty, and perseverance rather than effortless certainty.
Jacob has twelve sons, whose descendants the biblical narrative presents as the tribes of Israel. Later, according to the book of Exodus, the Israelites are enslaved in Egypt, and Moses confronts Pharaoh and leads them toward freedom under God’s guidance. Their journey culminates at Mount Sinai, where the people enter a covenant that calls for exclusive loyalty to God and a life ordered by divine commandments. The Ten Commandments are the most familiar expression of this teaching, but traditional rabbinic enumeration identifies 613 mitzvot, or commandments, in the Torah as a whole.
The Exodus and Sinai narratives provide more than an origin story. They connect freedom to responsibility: a people delivered from oppression are instructed to create a community governed by obligations toward God and other human beings. Jewish festivals, prayers, and ethical teachings repeatedly return to these events. Historians cannot independently confirm the narratives of the patriarchs, the Exodus, or Sinai in the form presented by scripture, but their place in Jewish religious memory is beyond dispute.
From Israelite Kingdoms to Rabbinic Judaism
The biblical story eventually moves from wandering tribes to kings and a sacred city. King David is traditionally credited with making Jerusalem the centre of a united Israelite kingdom, while his son Solomon is credited with building the First Temple. According to scripture, the Temple housed the Ark of the Covenant, and its innermost sanctuary signified a uniquely holy space. The scale of David and Solomon’s kingdom and some details of the early monarchy remain debated among historians and archaeologists, but the Temple’s later importance to Jewish worship is unmistakable.
The biblical account says that the kingdom divided after Solomon’s reign into Israel in the north and Judah in the south. The southern kingdom, centred on Jerusalem, is especially important to the later history of Judaism and the name Jew, which is historically connected with Judah and its inhabitants. In the late eighth century BCE, Assyria conquered the northern Kingdom of Israel, commonly dated to 722 BCE. Judah survived for another century and more, though it faced the pressures of much larger empires.
In 587 or 586 BCE, Babylonian forces destroyed Jerusalem and the First Temple. Members of Judah’s population, particularly its elite, were deported to Babylonia, while others remained in the land or migrated elsewhere. The experience of destruction and displacement became a turning point in Jewish memory: how could the people remain faithful to their covenant when their kingdom and sanctuary had fallen? Biblical literature from and about this era wrestles with loss, wrongdoing, hope, and the possibility of restoration.
Another imperial conquest changed the situation. Cyrus the Great took Babylon in 539 BCE, and Persian rule permitted exiled communities, including Judeans, to rebuild aspects of their religious life. Cyrus did not personally rebuild the Temple, as the story is sometimes simplified. The Second Temple was completed later under Persian administration, traditionally dated to 516/515 BCE, a distinction reflected in historical treatments of Cyrus and his imperial policies.
Jerusalem again became a focus of sacrifice, pilgrimage, priesthood, and religious authority. Yet Jewish life was no longer confined to a single political territory: established communities in Babylonia and elsewhere maintained connections with the homeland while developing their own institutions. Judaism during the Second Temple period was diverse, with different groups disputing how the law should be understood, how the Temple should function, and what God’s future intervention might look like. The Torah increasingly occupied a central place in the community’s self-understanding.
In 70 CE, Roman forces destroyed the Second Temple during the First Jewish–Roman War. The event was devastating, but it did not create the diaspora from nothing; Jewish communities had lived beyond Judea for centuries. Further conflict, particularly the Bar Kokhba revolt of 132–135 CE, brought additional destruction and displacement. The wider story of the city and its changing religious significance is explored in the history of Jerusalem.
With the Temple gone, forms of Jewish life centred on study, prayer, communal institutions, and observance became even more important. Rabbis developed and transmitted ways of interpreting the Torah that could guide life without an operating sanctuary or independent Jewish kingdom. Synagogues had existed before 70 CE, but their place in Jewish religious and social life expanded. Over many centuries, the rabbinic tradition came to shape much of what is now recognised as Judaism, although Jewish communities did not always interpret or practise it identically.
Jewish history after antiquity unfolded across the Middle East, North Africa, Europe, and eventually much of the world. Communities contributed to commerce, scholarship, philosophy, poetry, and local cultures, while also suffering discrimination, expulsions, forced conversion, and violent persecution. The Holocaust, known in Hebrew as the Shoah, brought the systematic murder of approximately six million Jews under Nazi Germany and its collaborators. The establishment of Israel in 1948 transformed Jewish political life, but it did not end the diaspora: millions of Jews continued, and continue, to live elsewhere. Jewish history cannot be reduced either to exile and suffering or to the history of the modern state.
One God, Covenant, and Human Responsibility
The most recognisable theological feature of Judaism is its devotion to one God, understood in classical Jewish teaching as eternal, creator of the universe, and the source of moral obligation. This God is not one powerful deity competing with others, nor a being with divine children or equals. The declaration known as the Shema, drawn from Deuteronomy, has become one of Judaism’s central expressions of divine unity and loyalty to God. Its words are recited in Jewish prayer and hold a place in religious life far beyond abstract theology.
It is important, however, not to imagine that every ancient Israelite always practised monotheism in its later, fully developed form. The historical evidence points to a long process in which Israelite and Judean worship existed within the religious environment of ancient Canaan and gradually developed stronger demands for exclusive worship. Scholars debate its chronology and stages; a study of Israelite and Judean religions helps distinguish that historical question from the tradition’s own account of revelation. Modern Jewish belief is not diminished by recognising that religious texts and historical reconstruction ask different questions.
Jewish scripture uses several names and titles for God. Elohim appears frequently, while four Hebrew letters, YHWH, form the divine name often called the Tetragrammaton. Its ancient pronunciation is uncertain, and many observant Jews avoid pronouncing it, saying Adonai (“Lord”) in prayer or Hashem (“the Name”) in ordinary conversation. Some also write “G-d” in informal English as a gesture of reverence, although customs differ.
The covenant makes this theology personal and practical. God is presented as attentive to human affairs, while people are expected to choose, act, repent, and take responsibility for one another. The story of Jacob wrestling through the night captures the possibility of an engaged, questioning relationship rather than passive obedience. There are also Jews who understand God metaphorically, who doubt conventional supernatural beliefs, or who live Jewishly without religious faith. Judaism has a substantial tradition of debate, and agreement on every theological proposition is not a prerequisite for every form of Jewish belonging.
The Torah, Tanakh, and Talmud
The most sacred textual foundation of Judaism is the Torah, commonly called the Five Books of Moses: Genesis, Exodus, Leviticus, Numbers, and Deuteronomy. It contains the narratives of Creation, the patriarchs and matriarchs, the Exodus, and the wilderness, as well as commandments governing worship, food, family relations, justice, and communal life. For traditionally observant Jews, it is divine teaching, read publicly from a handwritten scroll. The word Torah can also mean teaching more broadly, not only the five-book collection.
Those books form the first part of the Tanakh, the Hebrew Bible. Its name is an acronym for three divisions: Torah (Teaching or Law), Nevi’im (Prophets), and Ketuvim (Writings). The Prophets include narratives about Israel and Judah and the voices of figures who challenge kings and communities on fidelity, injustice, and worship. The Writings contain a striking variety of works, including Psalms, Proverbs, Job, and other poetry, wisdom, and historical texts. These books do not all speak in one literary voice, which is part of their richness.
Christians often refer to much of this material as the Old Testament, but Jews do not call it that. The Christian designation presupposes a New Testament that Judaism does not recognise as its scripture, and Christian arrangements and canons of these writings can differ from the Jewish Tanakh. Using the Jewish names also helps avoid a mistaken impression that the Hebrew Bible was merely a preliminary version of another religion’s sacred collection.
Judaism does not treat scripture as a text whose meaning is always obvious from a single reading. The commandments raise practical questions: what counts as work on a day of rest, how should conflicting obligations be reconciled, and what does a biblical rule mean in circumstances the text never describes? Rabbinic Judaism developed the idea of an Oral Torah, a tradition of interpretation and legal reasoning transmitted alongside the written text. This helps explain why Jewish religious law involves sustained argument as much as the preservation of ancient words.
Around 200 CE, teachings of earlier rabbis were compiled into the Mishnah, an organised collection addressing agriculture, festivals, family law, civil disputes, sacred things, and purity. Later generations discussed and analysed its teachings in the Gemara. Together, Mishnah and Gemara form the Talmud, which survives in two principal traditions: the Jerusalem Talmud, associated with rabbinic centres in Roman Palestine, and the more extensive Babylonian Talmud. It is therefore misleading to describe the Talmud as one fixed set of 38 volumes; editions, layouts, and counts vary.
What makes the Talmud distinctive is the way it preserves disagreements. On the same page, a reader may encounter a question, a proposed answer, an objection drawn from another teaching, a hypothetical example, and a further response attributed to a scholar of another generation. As this introduction to the Talmud’s structure and purpose explains, it combines law with stories, ethics, interpretation, and wider reflection. Its arguments are not simply chaos waiting for an answer: the process of reasoning itself is part of the tradition.
The wider body of Jewish law is called halakha, a term associated with the path one walks. It draws on scripture, rabbinic texts, later legal codes, commentaries, and community practice. Observance and authority differ across Jewish movements, but the underlying relationship between text and interpretation helps explain how a tradition rooted in antiquity has continued to address new questions across very different societies.
Justice, the Messiah, and the World to Come
Judaism’s concern with correct conduct reaches well beyond ritual. Tzedakah is often translated as charity, but its roots lie in justice and righteousness: helping people in need is not only a generous extra, but a responsibility. The Torah instructs landowners not to harvest every corner of a field or collect every last grape, leaving something for the poor and the stranger. This agricultural example captures an enduring idea: property and prosperity come with obligations to others.
Some Jewish traditions encourage giving a tenth of one’s income to charitable causes, often discussed in connection with ma’aser, or tithing. Yet rules and customary expectations vary, and the percentage should not be presented as a universal requirement for every Jew. The broader ethic also encompasses fair dealing, protecting the vulnerable, care for neighbours, and justice in communal life. A religious life concerned with God’s commandments is meant to shape the world people inhabit now, not merely secure rewards after death.
What, then, does Judaism teach about the afterlife? There is no single, uniformly accepted answer. The Hebrew Bible often focuses more on life, covenant, land, and collective fate than on detailed descriptions of individual destinations after death. It refers to Sheol, a shadowy realm of the dead, but later Jewish literature developed a wider vocabulary that includes Gan Eden, Gehinnom, resurrection, and Olam Ha-Ba, the World to Come. These ideas have been interpreted differently across periods and communities.
Many traditional Jewish beliefs look toward a future Messiah, or Mashiach: a human leader associated with the restoration of Israel, justice, peace, and a transformed world. Certain classical accounts anticipate a restored Temple, the gathering of exiles, and an age without war or oppression. Judaism generally does not accept the Christian claim that Jesus fulfilled the messianic role, although individual understandings of messianism vary widely. Some modern Jewish movements emphasise a messianic age of social and moral renewal rather than expectation of one identifiable person.
Resurrection of the dead is important in classical rabbinic theology and traditional liturgy, but it is not embraced in the same way by all Jews. The relationship between resurrection, the Messiah, and the World to Come is itself a subject of debate. Jewish burial traditions commonly emphasise respect for the body and prompt burial; traditional Jewish law generally prohibits cremation, though practice varies by community. It would be too simple to say these customs exist solely to keep a body intact for resurrection, since dignity and care for the dead are substantial concerns in their own right.
The uncertainty surrounding ultimate destiny is one reason the present life occupies such a powerful place in Jewish ethics. Religious observance is not simply a system of transactions in exchange for heaven. Whether expressed through prayer, study, justice, family obligations, or communal responsibility, the central challenge is how to live faithfully and well in the world people actually share.
Jewish Identity: One People, Many Communities
Judaism is unusual only if religion is assumed to be nothing more than a collection of personal beliefs. Jewish identity can refer to a faith, a people, a shared history, inherited traditions, and cultural belonging, often in overlapping combinations. A person may identify as Jewish without regularly attending synagogue or believing in a personal God. Equally, someone may join the Jewish people through conversion rather than ancestry. Jews do not constitute one race, and Jewish communities include people with widely varied appearances and backgrounds.
Traditional Jewish law generally understands Jewish status as inherited through a Jewish mother or acquired through an accepted conversion. Some contemporary movements use different criteria. Reform Judaism in North America, for example, recognises children with one Jewish parent who are raised with a Jewish identity and meet its communal requirements, while Orthodox and Conservative authorities generally maintain traditional matrilineal rules. These differences can have practical consequences when people move between communities or seek recognition of a marriage or conversion.
Jewish religious identity and Jewish cultural identity also do not map neatly onto modern nationalities. Across many centuries, Jewish communities lived among different languages, rulers, and neighbours while maintaining distinctive religious calendars, learning traditions, food practices, and family customs. The resulting diversity is not a recent departure from some perfectly uniform past. It is part of what allowed Jewish life to survive and change across long distances and radically different historical circumstances.
The Ashkenazi communities developed chiefly in Central and Eastern Europe. Their religious practices, scholarship, music, and food were shaped by the cultures around them as well as by specifically Jewish traditions. Yiddish, historically spoken by many Ashkenazi Jews, is a Germanic language with substantial Hebrew-Aramaic elements and influences from Slavic and other languages. Words such as chutzpah, klutz, and bupkis later entered familiar English usage, especially through Jewish life and popular culture in North America.
Sephardi history has its roots in the Jewish communities of the Iberian Peninsula. The expulsions from Spain in 1492 and Portugal’s subsequent policies uprooted large populations and helped establish or strengthen Sephardi communities across North Africa, the Ottoman Empire, and beyond. Some preserved Ladino, or Judeo-Spanish, while adapting their religious life and cuisine to new surroundings. Food, pronunciation, melodies, and festival customs often differed from Ashkenazi practices, even where the same central texts and commandments were shared.
These two traditions do not exhaust Jewish diversity. Mizrahi is a widely used modern term for Jews from Middle Eastern and related communities, including those historically established in Iraq, Iran, Syria, and Yemen; the boundary between Sephardi and Mizrahi identities can overlap. Ethiopian Jews, often known as Beta Israel, developed distinctive practices and histories, while Jewish communities also existed in India, the Caucasus, Central Asia, and China. Some traditions remained connected through trade, scholarship, or migration; others experienced long periods of relative separation.
Differences become visible in ordinary details. Pickled herring in an Ashkenazi kitchen and couscous in a Sephardi household illustrate regional culinary influences, not fixed rules about what members of either community eat. Ashkenazi pronunciation of Shabbat may sound closer to Shabbos in some settings, while Sephardi and many Israeli traditions use Shabbat. These examples demonstrate how a shared religious inheritance takes on local accents.
The modern Jewish world also contains religious movements with different approaches to authority and change. Orthodox Judaism generally treats halakha as binding and places a high value on continuity with inherited legal practice, although Orthodox communities differ among themselves. Hasidic Judaism is one stream within Orthodox Judaism, known for particular spiritual teachings, communal patterns, and, in some communities, distinctive clothing. Neither Hasidic Jews nor their visual appearance represent all Orthodox Jews.
Conservative Judaism, also called Masorti in many settings, values traditional Jewish law while allowing for historical scholarship and evolving interpretation. Reform Judaism generally gives greater scope to individual autonomy, changing social circumstances, and revised understandings of ritual obligation. Reconstructionist Judaism approaches Judaism as an evolving religious civilisation, with broad room for rethinking belief and practice. These labels do not encompass every community, and many Jews identify simply as traditional, secular, cultural, unaffiliated, or something else entirely.
The experience of persecution has also shaped Jewish solidarity, but Jewish identity is not defined only by hostility from outsiders. Diaspora communities developed literature, music, philosophy, commercial networks, institutions of charity, and profound local attachments. In the twentieth century, genocide, migration, and the creation of Israel dramatically altered the distribution of Jewish populations, leaving Israel and the United States home to particularly large communities. The shared history matters, but it does not erase the different ways Jewish people understand themselves today.
Shabbat, Kosher Food, and Jewish Daily Life
The weekly rhythm of Jewish life is anchored by Shabbat, the Sabbath, which begins at sunset on Friday and ends after nightfall on Saturday. Its biblical foundation is the seventh day of Creation, when God rests, and it also recalls the freedom of a people no longer enslaved to endless labour. Shabbat is therefore both a commandment and a change of pace: time deliberately set apart from ordinary production and consumption.
In traditionally observant households, its arrival may be marked by lighting candles, blessing wine or grape juice, sharing bread, attending synagogue, and sitting down to a family meal. Prayer, reading, visiting, conversation, and rest can give the day a distinctive atmosphere. Traditional Jewish law prohibits categories of creative work known as melakhah, a concept more precise than simply avoiding physical effort. The restrictions can affect cooking, business, shopping, driving, electronic devices, and other activities, although their application requires detailed interpretation.
Not every Jew observes these restrictions, and some families retain the Friday evening meal or the idea of rest without following traditional prohibitions. That variation does not make Shabbat insignificant. Even where observance differs, it remains one of the clearest examples of how Jewish tradition gives religious meaning to the structure of everyday time. The shared calendar creates recurring opportunities for reflection and belonging.
Food is another area in which commandments become ordinary practice. Kashrut is the body of Jewish dietary law, and food that meets its requirements is described as kosher. The Torah permits meat from certain land animals that both chew the cud and have fully split hooves, such as cattle and sheep. Pigs have split hooves but do not chew the cud, while rabbits do not meet the required conditions; neither is kosher. Permitted fish must have fins and scales, which excludes shellfish and many other aquatic animals.
The rules also distinguish permitted and forbidden birds, and kosher meat must come from an eligible animal slaughtered according to the requirements of shechita by a trained practitioner. Blood is prohibited for consumption, so meat is prepared through prescribed processes, commonly salting or broiling, to remove it. These requirements are more involved than simply choosing an animal from an approved list. Some practices differ among Jewish legal authorities and communities.
Another major principle is the separation of meat and dairy. Traditional kosher kitchens may maintain different utensils, dishes, and preparation areas for the two, with waiting periods between eating them. Foods classified as pareve, such as many fruits, vegetables, grains, and eggs, can ordinarily be eaten with either, though ingredients and preparation still matter. Kosher certification symbols help consumers identify products whose sourcing and manufacture have been supervised; an explanation of kosher food and its rules shows why the system extends far beyond a list of prohibited foods.
Kashrut can shape shopping, hospitality, travel, and family meals. Some Jewish people observe it rigorously, others follow selected rules, and many do not keep kosher at all. As with Shabbat, the key to understanding the practice is not to treat one pattern of observance as universal, but to see how a religious framework can turn repeated daily choices into expressions of identity and commitment.
The Synagogue, Jewish Holidays, and Ritual Traditions
A synagogue is a place for Jewish communal worship, study, and gathering. Its precise layout varies, but a central feature is the ark, where Torah scrolls are kept, and a reading platform, often called a bimah, from which the text may be read aloud. The scroll is handwritten in Hebrew by a trained scribe and treated with particular care. Public readings divide the Torah into portions that allow congregations to return to its narratives and commandments through a recurring cycle.
A rabbi is a trained teacher and interpreter of Jewish tradition and law, not a priest who must mediate between a congregation and God. Rabbis may teach, advise, lead services, officiate at marriages and funerals, and guide communities through ethical or practical questions. However, Jewish prayer does not always require a rabbi to lead it, and some communal prayers traditionally require a minyan, a quorum whose composition is understood differently across denominations. Synagogues existed in antiquity before the Second Temple fell and gained additional importance afterward.
Many worshippers cover their heads with a kippah, also called a yarmulke, as a sign of reverence and awareness of God. Some wear one throughout the day, while others do so during prayer, study, or synagogue attendance. In certain Orthodox communities, men or boys wear sidecurls called payot, drawing on a biblical prohibition traditionally interpreted as restricting the shaving of the head’s corners. These visible customs vary considerably and should not be confused with universal requirements for Jewish appearance.
Religious life is marked by moments in an individual’s life as well as by the weekly calendar. Brit milah may welcome a baby boy into the covenant; other naming and welcoming ceremonies are also practised. A bar mitzvah or bat mitzvah marks the assumption of religious responsibilities, traditionally associated with age thirteen for boys and twelve or thirteen for girls, depending on the community. Weddings, mourning practices, and communal support at times of loss give family milestones religious and social meaning.
The annual calendar returns repeatedly to the tradition’s formative memories. Passover, or Pesach, remembers the Exodus through storytelling and a ritual meal called the seder. Shavuot has agricultural roots and is associated in Jewish tradition with the giving of the Torah at Sinai. Sukkot recalls the Israelites’ wilderness journey through temporary booths and also carries harvest themes. Each festival combines ancient narratives with customs that have developed over generations.
Rosh Hashanah, the Jewish New Year, opens a period of reflection culminating in Yom Kippur, the Day of Atonement, devoted to repentance, fasting in traditionally observant communities, and reconciliation. Hanukkah commemorates the rededication of the Temple after the Maccabean revolt, while Purim celebrates deliverance as recounted in the book of Esther. These holidays are not interchangeable, and they do not all have the same legal or religious standing. Together they demonstrate how Jewish communities remember history not only by reading about it, but by arranging meals, prayers, rituals, and time around it.
There is no single level of observance that captures every Jewish life. A synagogue service in one city may differ markedly from another, just as a festival meal in a Persian, Moroccan, Ethiopian, or Polish Jewish household may draw on different languages and traditions. Yet the repeated act of gathering around sacred texts, shared memories, and communal practices creates recognisable connections across that diversity.
Judaism has survived extraordinary changes in political power, geography, language, and religious practice because its continuity has never depended on one institution or one unchanging cultural form. The covenant gives its sacred story a beginning, the Torah and generations of interpretation provide a vocabulary for responsibility, and communities give those teachings everyday expression. What unites Jewish life is not identical belief or observance, but a continuing relationship with a shared inheritance—one that can be studied, argued over, celebrated, adapted, and handed forward.
