Jewish life rests on a specific number: 613. It is the traditional count of commandments in the Torah — 248 positive (“do this”) and 365 negative (“do not do that”). The arithmetic is said to correspond to the limbs of the body and the days of the year: a whole person, a whole calendar, given over to a purpose.

Where the number comes from

The Torah does not list them in a neat catalogue. The count was derived by the sages — most famously codified by Maimonides — by reading the written law carefully and identifying each distinct instruction. Not every verse is a mitzvah; that is part of the interpretive work.

What they cover

The range is enormous, and that is the point. The mitzvot touch prayer and festivals, of course — but also business ethics, speech, treatment of workers, care for animals, honesty in weights and measures, and the way we treat the stranger. Nothing human is outside their reach.

• Between us and G-d: prayer, Shabbat, holidays, kosher, tefillin.
• Between us and others: honesty, charity, kindness, guarding speech.
• Between us and ourselves: discipline, gratitude, moderation.

The sages taught that all of them hang on a few great principles — loving G-d, loving your neighbor, and walking humbly.

Why so many

A person does not need 613 rules to be good. But Jews are asked for a life, not a feeling. The mitzvot are the architecture of that life: a thousand small hinges on which intention can swing into action. Every day offers outlets — a blessing, a coin for the poor, a kind word withheld or offered.

Where to begin

Nobody starts by keeping all 613. You begin with one, keep it well, and add another. The tradition has always understood this: the mitzvot are not a hurdle to clear but a path to walk, one step at a time.
