The Tetragrammaton and the Number 26
Four letters, one of the most discussed totals in Hebrew gematria, and a set of related numbers derived from the same name.
The Calculation
The four letter divine name is יהוה: yod 10, he 5, vav 6, he 5. The total is 26. Under Mispar Siduri, the ordinal method, the same letters give 10 + 5 + 6 + 5 counted by position: yod is 10th, he 5th, vav 6th, so 26 again, one of the coincidences of the ladder's design.
Where 26 Appears
Commentators return to the number constantly, often noting where a phrase or a count in the text matches it. The interest is not that 26 is unusual, but that the name is treated as saturating the text, so its number is looked for.
The number 45 is related: the name spelled out in full, each letter written as its own word, totals 45 under one common spelling, which is the value of אדם, adam, "man". That pairing is heavily used in kabbalistic literature.
The 15 and 17 Problem
A practical consequence of this ladder shows up in ordinary Hebrew numerals. Fifteen would naturally be written yod-he, and sixteen yod-vav, but both combinations spell parts of the divine name. Hebrew avoids this by writing 15 as tet-vav (9 + 6) and 16 as tet-zayin (9 + 7).
This is worth knowing because it is a rare case where gematria visibly changed how a language writes its numbers, rather than merely how a text is interpreted. If you have wondered why the fifteenth of a Hebrew month is written the way it is, that is the reason.
Reading the Commentary Carefully
Because 26 is small, it is reachable by a very large number of short words and phrases. A commentator noting a match is making a literary point within an argument, not offering statistical evidence. The same match found by searching a text for occurrences of 26 would mean nothing at all, because the search space is enormous and the target is common.
This is the general rule for small totals: the smaller the number, the more words share it, and the less any individual match can carry.
Check the Arithmetic
The Hebrew calculator handles the name directly, and the letter chart gives every value used. For the wider context of numbers like this, see the lesson on recurring numbers.
Frequently Asked Questions
What is the gematria of the Tetragrammaton?
26, from yod 10, he 5, vav 6 and he 5, under the standard method.
Why is 15 written as tet-vav in Hebrew?
Because the natural spelling yod-he would reproduce part of the divine name, so 9 + 6 is used instead. The same applies to 16.
What is the connection between 45 and adam?
The divine name written out in full, letter names spelled as words, totals 45 under one common spelling, matching the value of adam, meaning man.
