Gematria in the Bible

The short answer

The Bible contains numbers, not gematria. Gematria is what readers did with those numbers afterwards — and the earliest of them were doing it within a century or two of the texts being written.

Three things are true at once. The word gematria is rabbinic Hebrew, first found in the list of hermeneutic rules attributed to R. Eliezer ben Jose ha-Gelili around 200 CE; the Jewish Encyclopedia is explicit that the Bible itself contains no numerical gematria^{[1] Source: Gematria}. At the same time, Greek-speaking readers of the New Testament were already computing names in the first and second centuries, because Greek letters simply were numbers. And one verse — Revelation 13:18 — openly asks its reader to calculate. So the honest picture is neither “the Bible is full of hidden codes” nor “gematria has nothing to do with the Bible”. It is: a handful of biblical numbers, a long history of reading them, and a clear line between the two.

Hebrew Bible: numbers read as words

The classical Jewish examples all work the same way: the text gives a number, and the interpreter finds a word with that value. The value is checkable; the connection is an interpretation.

318 and Eliezer

Genesis 14:14 says Abram “led forth his trained men, born in his house, three hundred eighteen of them” to rescue Lot^{[2] Source: Genesis 14:14}. The Talmud, in Nedarim 32a, reports the view that Abram took only one man — his servant Eliezer — because אליעזר = 318^{[3] Source: Nedarim 32a}. This is the most-quoted gematria in Jewish literature, and it is a good specimen: the number is in the text, the name is in the text (Genesis 15:2), and the equation is exact.

The same number received a completely different reading in Greek. The Epistle of Barnabas, a Christian text of the late first or early second century, notes that 318 in Greek numerals is ΤΙΗ, and reads Τ (300) as the cross and ΙΗ (18) as the first two letters of Ἰησοῦς — Abraham, it says, was foreseeing Jesus and the cross^{[4] Source: The Epistle of Barnabas, chapter 9}. The site’s engine confirms ΤΙΗ = 318. Two communities, one verse, two incompatible conclusions from the same arithmetic — which is the first lesson this page has to teach.

30 days and the Nazirite

Numbers 6:5 says of the Nazirite that “he shall be holy” — קדוש יהיה^{[5] Source: Numbers 6:5}. The Torah never states how long a vow lasts if no term is specified. Nazir 5a supplies thirty days, because יהיה = 30^{[6] Source: Nazir 5a}. This is the one point of Jewish law traditionally grounded on a gematria, and even here the Encyclopedia notes it was probably an asmakta — a scriptural peg for a rule that had other support^{[1] Source: Gematria}.

Two more classics

Jacob’s ladder (סלם, Genesis 28:12) and Sinai (סיני) share a value — סלם = 130 · סיני = 130 — which medieval commentators took to mean the ladder foreshadowed the giving of the Torah. And the Talmudic proverb “when wine goes in, secrets come out” rests on יין = 70 · סוד = 70. Neither is in the biblical text; both are readings of it, offered as illustrations rather than proofs, which is how the tradition itself ranked them^{[15] Source: Gematria}.

Letter patterns that are not gematria

The Hebrew Bible does contain deliberate alphabetic structures, and they are often confused with gematria. Psalm 119 has twenty-two stanzas of eight verses, each stanza beginning with the next letter of the alphabet; Lamentations 1–4 and Psalms 25, 34, 111, 112 and 145 are acrostics too. These are real, authorial and ancient — but they use letters as letters, in order, not as numbers. No sum is involved. Likewise the symbolic numbers of scripture (7, 12, 40, 70) are counts with conventional meanings; nothing in the text converts them to or from words. Gematria proper begins only when a number and a word are set equal, and the Bible never does that explicitly.

666 and 616

Revelation 13:18: “Let anyone with understanding calculate the number of the beast, for it is the number of a person. Its number is six hundred sixty-six”^{[7] Source: Revelation 13:18}. This is the only verse in scripture that presents a number as the value of a name and asks the reader to solve it — which is exactly how isopsephy riddles worked in the Greek world, where a Pompeian could write “I love her whose number is 545”^{[11] Source: Isopsephy}.

The earliest attempt at a solution is Irenaeus, around 180 CE. He tries three Greek words — Ευανθας = 666 · Λατεινος = 666 · Τειταν = 666 — and declines to choose, remarking that many names fit. He also knows manuscripts that read 616, which he blames on copyists^{[8] Source: Against Heresies, Book V, chapter 30}. The 616 reading is genuine and old: Papyrus 115, a third-century fragment from Oxyrhynchus, writes the number as χιϛ^{[10] Source: Papyrus 115}.

The reading most modern scholars favour was proposed in the nineteenth century and works in Hebrew, not Greek. The emperor’s name and title transliterated as נרון קסר (Neron Kesar) sums to 666; the Latin-style spelling without the final n, נרו קסר (Nero Kesar), sums to 616^{[9] Source: Number of the beast}. That a single hypothesis explains both manuscript readings is the strongest argument for it. It remains an argument, not a proof; the 666 page sets out the full history and the counter-cases.

The other 666 in scripture is more prosaic: Solomon received “six hundred sixty-six talents of gold” in a year (1 Kings 10:14, 2 Chronicles 9:13). Whether Revelation alludes to it is debated; the text does not say.

888: the name of Jesus

In Greek, Ἰησοῦς = 888. The number was noticed early: the Sibylline Oracles, a collection with Christian material from the second century, present the name of the coming saviour as a number whose “units are eight, and tens as many, and hundreds eight” — 888^{[11] Source: Isopsephy}. Later Christian writers set 888 against 666 as the true name against the false one. This is a legitimate isopsephy of a real Greek spelling; it is also, like every such value, one of many words that sum to 888.

Note what it is not. English values of “Jesus” — 74 in English Ordinal, 985 in the Agrippa (“Jewish”) table, 444 in Sumerian — come from tables invented between the sixteenth and twentieth centuries, and no ancient reader could have computed them. The number meanings page keeps the two kinds of value apart.

153 fish

John 21:11 counts the miraculous catch at “a hundred fifty-three” large fish^{[12] Source: John 21:11}. No number in the Gospels has attracted more explanations. Augustine’s is the most famous: 153 is the triangular number of 17 — 1 + 2 + … + 17 = 153 — and 17 is the Ten Commandments plus the seven gifts of the Spirit^{[13] Source: Tractates on the Gospel of John, Tractate 122}. This is number symbolism, not gematria: no word is being summed. Gematria readings came later — various Hebrew and Greek phrases have been found that total 153 — and mathematicians have added that it is also the sum of the first five factorials and equals 1³ + 5³ + 3³^{[14] Source: 153 (number)}. The text offers a count of fish. Everything else is the reader’s.

The one verse that invites calculation

It is worth being precise about the status of Revelation 13:18, because the whole question of “gematria in the Bible” turns on it. It is the single verse that (a) gives a number, (b) says it is the number of a name, and (c) tells the reader to calculate. In doing so it assumes its audience knows the Greek practice of isopsephy. That is real evidence that a biblical author used letter-values — but it is evidence of one riddle, not of a method running under the whole text. Nothing else in either testament makes the same request.

Reading these honestly

• Separate the number from the reading. 318 is in Genesis; “Eliezer” and “ΤΙΗ” are in the Talmud and Barnabas. Both readings are old and both are interpretations.
• Use the right alphabet. Hebrew values apply to Hebrew spellings, Greek to Greek. English ciphers say nothing about what an ancient text meant.
• Remember how many words share a value. Irenaeus found three names for 666 without trying hard; the accuracy page measures how common such matches are.
• Note the tradition’s own rank for it. The Mishnah calls gematria a side-dish of wisdom; the one legal use is treated as a support, not a source^{[1] Source: Gematria}.
