The Mitzvot and Key Moral Principles
What Are the Mitzvot?
The word Mitzvot (singular: mitzvah) means “commandments.” Jewish tradition teaches that the Torah contains 613 commandments in total. These cover every aspect of Jewish life — from prayer and festival observance to diet, business ethics, social justice and family relationships. Observing the Mitzvot is how Jews live out their covenant relationship with G-d in everyday life. The Mitzvot are not seen as burdensome rules but as a gift — G-d’s guidance for living a holy and meaningful life.
Positive and Negative Commandments
The 613 Mitzvot are traditionally divided into two groups. Positive commandments (Hebrew: aseh, meaning “you shall”) are obligations to do something. There are 248 positive commandments. Examples include honoring parents, observing Shabbat and giving charity (tzedakah). Negative commandments (Hebrew: ta’ashe, meaning “you shall not”) are prohibitions. There are 365 negative commandments. Examples include not eating blood (Leviticus 7:26–27), not coveting another’s possessions, and not committing murder.
Deuteronomy 11:18–21 commands Jews to fix G-d’s words to their hearts and minds, to teach them to their children, and to bind them as signs on their hands — a passage that underpins the wearing of tefillin (phylacteries) and the fixing of mezuzot to doorposts. Numbers 15:37–41 commands the wearing of fringes (tzitzit) on garments as a reminder of the commandments. These physical practices turn daily life into a constant reminder of the covenant obligations.
Jewish tradition counts 613 Mitzvot in the Torah: 248 positive commandments (aseh — “you shall”) and 365 negative commandments (ta’ashe — “you shall not”). Different scholars have compiled slightly different lists, but the number 613 is the most widely accepted in rabbinic tradition.
Ethical and Ritual Mitzvot
The 613 Mitzvot can also be grouped into ethical Mitzvot and ritual Mitzvot. Ethical Mitzvot govern how Jews treat other people — they are fundamentally concerned with interpersonal relationships. The importance of interpersonal relationships as the principle underlying many ethical Mitzvot is a key theme in Jewish thought: commands about honesty in business, care for the poor and the stranger, fair wages and respect for elders all flow from the principle that all humans are created in the image of G-d (Genesis 1:27) and therefore deserve dignity. Ritual Mitzvot govern the relationship between a Jew and G-d — such as prayer, Shabbat observance, dietary laws (kashrut) and festival celebrations.
This distinction matters because some Mitzvot are fulfilled primarily through religious practice and worship, while others are fulfilled through moral conduct in daily life. However, in Jewish thought, the two categories are not separate: religious practice and ethical living reinforce each other. A person who keeps the dietary laws but treats others dishonestly is not living the fullness of Torah. Deuteronomy 30:19 expresses this holistic vision: “I have set before you life and death, blessings and curses. Now choose life.” This verse captures the idea that observing the Mitzvot — in all their dimensions — is the path of life and blessing.
Divine Providence refers to G-d’s ongoing care, guidance and oversight of the world. Jews believe that G-d is not absent after creation but remains actively involved. The Book of Jonah illustrates Divine Providence powerfully: G-d guides events — the storm, the great fish, the plant — to bring Jonah to fulfil his prophetic duty. Job 42:2 acknowledges: “I know that you can do all things; no purpose of yours can be thwarted.”
Yet Judaism also strongly affirms human free will. The Mitzvot only make sense if humans genuinely choose to obey or disobey them. Deuteronomy 30:19 (“choose life”) is a direct call to exercise free will. The tension between G-d’s providential knowledge and human freedom is a classic theme in Jewish philosophy, with thinkers like Maimonides arguing that G-d’s foreknowledge does not cancel human freedom, even if this is difficult to fully explain.
Pikuach Nefesh — The Sanctity of Life
Pikuach Nefesh is one of the most important moral principles in Judaism. It means literally “saving a soul” (or “watching over a life”) and establishes that the duty to save or preserve human life overrides nearly all other commandments. If keeping a Mitzvah would endanger a life, the Mitzvah must be set aside.
In practice, this means that on Shabbat — when work is normally forbidden — a doctor may (and must) work to save a life. An ill person may eat non-kosher food if that is all available to sustain them. The Talmud derives this principle partly from Leviticus 19:16 (“do not stand idly by the blood of your neighbour”) and partly from the general Torah teaching on the value of human life. Exodus 20:13 (“You shall not murder”) also establishes the sanctity of human life as a foundational principle.
Pikuach Nefesh (saving a soul) is the principle that preserving human life takes precedence over almost all other commandments. It means a Jew must break Shabbat restrictions, dietary laws or other Mitzvot if doing so is necessary to save a life. Only the prohibitions against murder, sexual immorality and idol worship cannot be overridden even to save a life.
Orthodox Jews regard all 613 Mitzvot as binding divine commands. They follow halachah (Jewish law) as determined by the Talmud and rabbinic rulings, and view the Mitzvot as G-d’s timeless instructions that cannot be changed or set aside by human preference.
Progressive (Reform) Jews believe the Mitzvot must be understood in historical context and may be reinterpreted or adapted for modern life. They tend to prioritise the ethical Mitzvot (justice, compassion, honesty) as the core of Jewish moral life, while treating some ritual Mitzvot as optional or symbolic. Conservative (Masorti) Jews take a middle position, accepting the binding nature of Jewish law but allowing careful, scholarly reinterpretation as times change. The existence of different scholarly lists of the 613 commandments (compiled by figures such as Maimonides) also shows that debate over the exact content of the Mitzvot has always been part of Jewish tradition.
