The Hidden Meanings of Numbers in Judaism


Numerology, the study of the symbolic meaning of numbers, has long been an integral part of Jewish thought and practice. Numbers hold a special significance in Judaism, with meanings that go beyond their quantitative value.

In this blog post, we’ll explore the mystical meanings behind key numbers in Jewish tradition and how they connect to core concepts in Judaism. From the Kabbalah to the Hebrew calendar, numbers reveal deeper truths about the universe and our place within it.

The Significance of Numbers in Judaism

Biblical Numbers

Numbers play an important role throughout the Hebrew Bible, which is filled with numeric patterns and repetitions. Certain numbers like 3, 7, and 40 echo throughout the Torah, signaling deeper symbolic meanings.

For example, the number seven represents completeness and perfection. The world was created in seven days, leading to the establishment of the Shabbat. There are seven branches on the Temple’s menorah. The Jewish calendar is full of sevens, with Shmita observed every seventh year and the Jubilee arriving after seven Shmita cycles.

The number three also carries great significance as a symbol of unity, representing the three Patriarchs — Abraham, Isaac and Jacob — as well as the three pilgrimage festivals of Passover, Shavuot and Sukkot.

Other numbers like 12 (the 12 Tribes of Israel) and 40 (the years in the desert) also had special resonance for biblical-era Jews. By noticing these numerical patterns, we can extract richer layers of meaning and divine intention.


One of the most well-known techniques of biblical numerology is gematria, in which Hebrew letters double as numbers. By calculating the numerical value of words and phrases, new layers of meaning can be revealed.

Gematria originated in the Mishnah before being more formally developed by Kabbalists. It’s an attempt to uncover deeper connections between words and phrases that share the same value. A famous example connects the Hebrew word for life (“chai”, with a value of 18) and the word for good luck (“tov”, also 18).

By matching up words of equivalent value, gematria finds hidden theological and mystical relationships. It’s one way that scholars and sages have plumbed the infinite depths of the Torah text over centuries of analysis.

The Kabbalah

The Jewish mystical tradition known as Kabbalah places great significance on numbers and their esoteric meanings. Kabbalistic schools like Chassidism used numerology extensively in their teachings.

According to Kabbalah, numbers represent the inner workings of creation and the mystical underpinnings of existence. The number 10, for instance, connects to the 10 Sefirot – the divine emanations through which God interacts with the material world.

By decoding numeric meaning, Kabbalists believe we can approach an understanding of the divine. Numbers in Kabbalah symbolize the endless creative potential that God used to design and sustain the universe.

Key Numbers in Judaism

Now that we’ve discussed the importance of numerology historically, let’s explore the symbolism of some significant numbers in depth:


The number one represents unity, oneness and singularity. God is united and whole. For monotheistic Judaism, one is the fundamental number that precedes all others, the source from which multiplicity emerges. One reflects the unified nature of God’s essence and divinity.


Two introduces dichotomy and contrast into the world – dark/light, land/sea, good/evil, and man/woman. Two represents the establishment of opposites and dualities that make free will possible. It also connects to the two versions of the Torah – the Written and Oral Torah.


As mentioned earlier, three symbolizes harmony. It embodies completeness, represented in the three Patriarchs, the three pilgrimage festivals, and multiple other Jewish triads. Three marks stability, balance, and synthesis.


The number four connects to the four seasons, four directions, four elements (fire, water, earth, air), and four letters in God’s essential name YHVH. It represents nature, the material world, and earthly existence.


The number six is imperfection, falling short of the complete seven. It relates to the six days of creation with the seventh being the day of rest. Six represents incompleteness, imperfection, and continuous progress still required.


We’ve covered seven’s meaning thoroughly already – it’s tied to holiness, perfection, blessings and rest on the Sabbath. By completing each cycle and bringing fullness, seven echoes God’s sovereignty and the goal of spiritual fulfillment.


Eight goes beyond seven, meaning infinity, transcendence, and the endless continuation of creation and human progress. It connects to Brit Milah on a baby’s eighth day and the eight candles of Hanukkah.


As we’ve seen with the 10 Sefirot, 10 indicates divine order, completion, and the structure of the universe. The 10 utterances through which God created the world also speak to 10’s meaning of a perfect divine plan.


The number twelve includes the 12 Tribes of Israel, 12 months in the Jewish calendar, 12 loaves of the showbread, and more. It unites 3 and 4, representing wholeness and Israel’s role in the material world.


Going beyond 12, the number 13 indicates God’s infinite transcendence. It’s associated with mystical experiences of the divine, since God exceeds any limitations. That’s why 13 attributes of mercy are described in Exodus.


Numerology reveals a mystical dimension within Judaism, connecting numbers to cosmological secrets. Studying the hidden meanings of numbers brings us closer to the infinite, divine nature of Creation.

The numerical patterns within Jewish texts and traditions are not random – they constitute a divine language requiring decipherment. By decoding the numerology of Judaism, we uncover profound theological and philosophical insights into God’s relationship with the universe and humanity. Numbers bridge the finite with the infinite.

So next time you come across a number in a Jewish context, consider what secrets it might hold! Numerology invites us to plumb the inexhaustible depths of Torah and identify the myriad pathways to religious meaning and mystical knowledge.
