Every quantitative study of the Tanakh — and Equidistant Letter Sequences are exactly that — stands or falls on a prior question: precisely which text are you measuring? This page answers that question for our search engine with single-letter precision: we document the full source chain, declare the counting rules, publish the complete table of all 39 books, and validate the total against the number the soferim have guarded for centuries.
The source, documented link by link
Our search engine does not use "some Hebrew text from the internet". It uses a specific edition with a public editorial history:
- Edition: Miqra According to the Masorah (MAM, מקרא על פי המסורה) — a digital edition of the Tanakh based on the Aleppo Codex (כתר ארם צובא, the most authoritative Masoretic manuscript, vocalized by Aharon ben Asher, 10th c.) and related manuscripts for the missing portions. Every editorial decision in MAM is publicly documented.
- Where it lives: MAM is developed and maintained at Hebrew Wikisource, under an open CC-BY-SA license.
- Our search engine starts from that text, book by book, and freezes it into a static corpus of our own, verified with SHA-256 fingerprints on every deployment of the site.
- For the Torah, on top of that base we apply the 9 documented Masoretic variants that produce the text of the Koren edition (304,805 letters) — the standard of ELS research. Here is the complete list of the 9 differences.
Counting methodology (the exact rules)
Tanakh counts are only comparable when the rules are declared. Ours, applied identically in this table and in the search engine's corpus:
- Letter: any character of the Hebrew alphabet (Unicode U+05D0 to U+05EA: the 22 letters plus the 5 final forms ך ם ן ף ץ). Vocalization (nikkud) and cantillation (te'amim) marks are not letters and are not counted.
- Written text (ketiv), not read text (qere): where the Masorah records a word written one way and read another, we count exclusively the ketiv — what is physically written in the scroll. This is the convention of classical ELS research.
- No editorial apparatus: MAM's footnotes (manuscript variants), the section markers {פ}/{ס} and all signaling elements are excluded: they are not letters of the Tanakh.
- Word: a sequence of Hebrew letters delimited by whitespace or maqaf (־). That is, words joined by maqaf count separately.
- Verse: each verse of the edition's standard Masoretic division.

The validation: why these numbers are trustworthy
Any table can be copied; a scientific table is validated. The soferic tradition — the scribes who copy scrolls letter by letter — has guarded the Sefer Torah count for centuries: 304,805 letters. Our computed Torah count gives exactly 304,805: since the search engine adopted the Koren edition as the canonical text of the Torah (the text of classical ELS research), the computed count and the soferic count match letter for letter.
The corpus is built from the MAM edition (Aleppo Codex) by applying the 9 documented Masoretic variants that separate it from the textus receptus — all of them plene/defective spelling cases (מלא/חסר) or equivalents — and is verified against the Koren reference text used by Eliyahu Rips. The result is frozen with SHA-256 fingerprints: not a single letter can change without the site detecting it. The validations converge:
- Torah letters: 304,805 — an exact match with the count of the standard scrolls and with the text of published ELS research.
- Torah words: 79,977 — the commonly cited reference count is 79,976 (Δ = 1, attributable to a borderline word-division case between editions).
- Torah verses: 5,847 — the Koren numbering, which counts Numbers 25:19 as a verse in its own right.
- Tanakh verses: 23,205 — within the transmitted Masoretic range (~23,200).
Why do other sites publish different numbers?
Compare "Bible letter count" tables online and you will find variation. It is almost always explained by four rarely-declared factors: the base edition (Aleppo, Leningrad, Koren, printed editions — they differ in plene/defective spelling), the treatment of ketiv/qere (do they count what is written, what is read, or both?), the word rule (does maqaf join or separate?), and silent contamination (editorial notes, markers and formatting characters counted as text). Our table declares all four decisions — which is why every number is defensible and reproducible.
In fact, preparing this study led us to improve the search engine itself: we detected that MAM's editorial footnotes and the duplicated qere were inflating the corpus by about 5,600 letters (~0.5%), and we fixed it. The current corpus is exactly the written text — the figures in this table.
Reproduce it yourself
Don't take our word for it: open the search engine, load any book (or the complete Tanakh) and compare the total letters reported in the information panel with this table. They match because they are the same count over the same text. The full procedure — source, cleaning, rules — is described above, and any programmer can replicate it in an afternoon from the MAM edition published on Hebrew Wikisource.
Note: the Torah corresponds to the Koren edition (see the article on our textual source); Nevi'im and Ketuvim, to the MAM edition frozen in our corpus and verified by checksums on every deployment of the site. The numbers in this table cannot change silently.
