A scribe in 13th-century Spain once stared at the word bereshit — “in the beginning” — and saw not just the first word of Genesis but the number 913. He counted the letters: bet (2), resh (200), aleph (1), shin (300), yod (10), tav (400). The sum was 913, which also equals the phrase et ha-shamayim ve-et ha-aretz — “the heavens and the earth.” He was not playing a game. He believed the Torah was composed by God with numbers woven into its letters, and that by reading those numbers, a person could glimpse the architecture of creation.
Gematria is the practice of assigning numerical values to Hebrew letters to uncover hidden relationships between words, phrases, and concepts in sacred texts. The most common system gives each of the 22 letters a value from 1 to 400, but there are variations. The earliest explicit mention of gematria appears in Jewish sources from the 1st century BCE, though the practice likely draws on older Mesopotamian and Greek number-letter systems.
Where Did Gematria Come From?
The word itself is Greek: geōmetria (geometry). Jewish scribes borrowed the term, but the concept predates the name. The earliest known Jewish text to use gematria explicitly is the Baraita of the Thirty-Two Rules, a 2nd-century CE collection of hermeneutic principles. Rule 29 is gematria. But the practice appears earlier: the Dead Sea Scrolls (3rd century BCE–1st century CE) contain passages that seem to play on numerical values of letters.
The real engine of gematria was the Sefer Yetzirah (Book of Creation), composed between the 3rd and 6th centuries CE. This short, cryptic work describes how God created the universe through 32 paths of wisdom: the 22 Hebrew letters plus the 10 sefirot (divine emanations). Each letter is assigned a number, a direction in space, and a bodily organ. The Sefer Yetzirah does not use gematria for exegesis, but it establishes the principle that letters are not arbitrary signs, they are building blocks with numeric weight.
Medieval Kabbalists took this further. In the 13th century, Abraham Abulafia developed a meditative system called Hokhmat ha-Tseruf (the Science of Combination), where practitioners would permute letters and calculate their values to reach ecstatic states. The Zohar (late 13th century) uses gematria extensively, though often in a loose, associative way. By the 16th century, Rabbi Moses Cordovero and Rabbi Isaac Luria had systematized gematria into a core tool of Kabbalistic interpretation.
For the people who used it, gematria was not a parlor trick. It was a way to confirm that the Torah contained every possible truth, because its letters were the raw material of reality. If two words shared a numerical value, they were connected at the level of divine language.
How Does Hebrew Letter Numbering Work?
The standard system, called Mispar Hekhrechi (absolute value), assigns values as follows:
- Aleph (א) = 1
- Bet (ב) = 2
- Gimel (ג) = 3
- Dalet (ד) = 4
- Heh (ה) = 5
- Vav (ו) = 6
- Zayin (ז) = 7
- Chet (ח) = 8
- Tet (ט) = 9
- Yod (י) = 10
- Kaf (כ) = 20
- Lamed (ל) = 30
- Mem (מ) = 40
- Nun (נ) = 50
- Samekh (ס) = 60
- Ayin (ע) = 70
- Peh (פ) = 80
- Tsadi (צ) = 90
- Qof (ק) = 100
- Resh (ר) = 200
- Shin (ש) = 300
- Tav (ת) = 400
Five letters have final forms (kaf sofit, mem sofit, nun sofit, peh sofit, tsadi sofit) that are sometimes counted as the same value as their standard forms, sometimes as 500, 600, 700, 800, and 900 respectively. The variation matters: in some calculations, the word Torah (תורה) equals 611 (tav=400, vav=6, resh=200, heh=5). But if you count the final heh as 5, it stays 611. If you used a system that gave final letters higher values, the number would shift.
There are at least a dozen methods: Mispar Gadol (large value, including final letters as higher numbers), Mispar Katan (reduced value, dropping tens and hundreds), Mispar Siduri (ordinal value, aleph=1, bet=2, etc., up to tav=22), and Mispar ha-Merubah (square of the letter’s value). Each method reveals different relationships. A Kabbalist would choose the method that best fit the text and the question.
What Does the Number Mean?
Every number in gematria carries symbolic weight, but the meanings are not fixed, they emerge from context. A few examples show how the system works.
The number 1 (aleph) is unity, the point before creation. 2 (bet) is duality, the house (bet means “house”) that contains difference. 3 (gimel) is movement, the camel (gimel means “camel”) that carries between worlds. These associations come from the letter names themselves, not just the numbers.
The most famous gematria in Jewish tradition is 18, the value of chai (חי, “life”). Chet = 8, yod = 10. Gifts of money in multiples of 18 are customary at weddings and bar mitzvahs. The practice is medieval or later, it does not appear in Talmudic sources, but it has become universal.
The Tetragrammaton, YHWH (יהוה), equals 26: yod=10, heh=5, vav=6, heh=5. This number is central to Kabbalistic meditation. The Zohar says that the 26 generations from Adam to Moses correspond to the 26 letters of the divine name (counting each letter individually). The number 26 also equals the word kavod (glory) in some calculations.
The word Torah (תורה) equals 611. Add the first two words of the Ten Commandments (Anokhi YHWH) and you also get 611. For Kabbalists, this proved that the entire Torah was contained in the first utterance at Sinai.
The number 613, the traditional count of commandments, appears as the value of Torah plus the first letter of Genesis (bet = 2), or as the sum of the 613 letters in the Ten Commandments (a claim that requires creative counting). The point is not mathematical precision. The point is that the numbers hold the text together.
How Is Gematria Used in Practice?
Gematria has three main applications: exegesis, meditation, and amulet-making.
Exegesis: A rabbi or Kabbalist encounters a difficult verse. They calculate the values of key words and look for other words with the same sum. If Genesis 49:10 says “the scepter shall not depart from Judah,” and the word for “scepter” (shevet) equals 312, which also equals the name Mashiach (Messiah), the connection is taken as a proof. This method appears in the Midrash and later in the Zohar.
Meditation: Abraham Abulafia’s system involved breathing exercises, head movements, and letter permutations. A practitioner would take a divine name, write its letters, calculate their values, and then combine them into new words. The goal was to “unseal the soul” and achieve prophecy. Abulafia wrote that the letters are “keys to the gates of wisdom.” His methods influenced later Jewish mystics and, through them, Renaissance Christian Kabbalists.
Amulets: The 72 names of God, derived from three verses in Exodus (14:19-21), are a gematria-based construction. Each verse has 72 letters. By arranging them in a grid, Kabbalists produced 72 three-letter names. These names, each with a numerical value, were inscribed on amulets for protection. The practice continues in some Jewish communities today.
In modern occultism, gematria was adopted by the Hermetic Order of the Golden Dawn (founded 1888) and later by Aleister Crowley. Crowley’s The Book of the Law (1904) contains the line “The word of the Law is Thelema,” and Thelema (Greek for “will”) has a gematria value of 93, which also equals Agape (love). Crowley’s system, called “English Qaballa,” attempts to apply gematria to English letters, but it is a 20th-century invention, not a continuation of Jewish tradition.
How Does Gematria Compare to Other Systems?
The Greek world had isopsephy, where letters of the Greek alphabet also carried numbers. The most famous example is 666, the “number of the beast” in Revelation 13:18, which is a gematria for Neron Kaisar (Nero Caesar) when written in Hebrew letters. The early Christians who decoded this were using Jewish gematria on a Greek text.
Arabic has abjad numerals, where the 28 letters of the Arabic alphabet are assigned values from 1 to 1000. Sufi mystics used abjad for similar purposes, finding hidden meanings in the Quran, constructing talismans, and meditating on divine names. The system predates Islam, originating in the Phoenician alphabet.
Jewish gematria differs from these in one crucial way: it is applied to a text believed to be literally dictated by God. The Torah’s letters are not arbitrary. Every stroke, every crown on a letter, is significant. Gematria is therefore not a human invention imposed on the text, it is a method of uncovering what was already there.
What Do People Get Wrong About Gematria?
The most common misconception is that gematria is a code for predicting the future. It is not. Kabbalists did not use it to forecast events. They used it to understand the structure of reality as revealed in scripture. When a modern numerologist says “the number 18 means life, so you will live a long life,” they are applying a folk interpretation, not the Kabbalistic method.
Another error is treating gematria as a single system. There are multiple methods, and the same word can yield different numbers depending on which method you choose. This flexibility is not a flaw, it is intentional. The Kabbalist selects the method that fits the context.
A third mistake is assuming gematria is exclusively Jewish. It appears in Greek, Arabic, and Latin traditions, and it has been adapted by Western occultism. But those adaptations often strip away the theological framework. Jewish gematria is inseparable from the belief that the Torah is the blueprint of creation. Without that belief, the numbers become arbitrary.
Finally, some people think gematria is about “hidden messages” planted by a human author. The medieval Kabbalists believed the author was God, and the messages were not hidden in the sense of being secret, they were hidden in the sense of being infinite. Every letter contained all others. Every number pointed to every other number. The work of gematria was never finished.
FAQ
What is the gematria value of 18?
18 is the value of the Hebrew word chai (חי), meaning “life.” It is the most widely recognized gematria in Jewish culture, used for gift-giving in multiples of 18.
How do you calculate gematria?
Add the numerical values of each Hebrew letter in a word or phrase. The standard system (Mispar Hekhrechi) assigns values from 1 (aleph) to 400 (tav). There are many variations, including ordinal and reduced methods.
Is gematria used in Christianity?
Yes, but primarily in early Christian interpretation of the New Testament. The number 666 in Revelation is a gematria for Nero Caesar. Some medieval Christian Kabbalists also used gematria, but it never became a mainstream Christian practice.
What is the difference between gematria and numerology?
Gematria is a specific system tied to the Hebrew alphabet and Jewish sacred texts. Numerology is a broader term for any system that assigns meaning to numbers, often divorced from a specific scriptural tradition. Gematria requires knowledge of Hebrew and the context of Torah.
Closing
Gematria is not a code to crack. It is a practice of attention, learning to see the weight of each letter, the way words connect across a text, the numbers that hold the universe together. For the Kabbalist, the Torah was not written in language alone. It was written in number, and number is the grammar of creation.
