# Significance of Gematria

Do any of the mepharshim write about the nature and validity of Gematria and deriving ideas from it. Some people I know are skeptical of Gematria and I'm wondering if one of the chachomim have addressed this issue.

I'm really not sure where to begin looking for the answer to this question.

• @newcomer rishonim generally treat gematriyot as mere asmachtot, rather than actual sources for laws. Apr 25, 2016 at 22:44
• Gmara in nazir for 30 Yom, but the Gematriot in Gemara are asmachtot Apr 26, 2016 at 14:02
• @mevaqesh First Tosfos in Gittin uses the Gematria of גט as the source for having 12 lines in the get. Aug 25, 2017 at 21:29

Since gematria is an alphanumeric system, it is best used within a mathematical framework within which the results associated with the use of gematria must be consistent. The framework must necessarily include axioms from which we develop definitions, lemmas, theorems, and corollaries. Indeed, the Method of Gematria can be precisely defined as follows:

Let V_1 and V_2 be two verses in the Bible. Let N_1 be the total gematria of a set of words in V_1. Let N_2 be the total gematria of a set of words in V_2. It is possible that V_1 and V_2 are contextually or thematically linked if and only if N_1=N_2.

This definition refers to words or expressions in the verses that are contextual or thematic. By Collins English Dictionary, the context of a word, sentence, or text consists of the words, sentences, or text before and after it which help to make its meaning clear. So once the Method of the Gematria establishes the association (N_1=N_2) between the two verses, V_1 and V_2, then several verses before and after them may need to be consulted for a better understanding of the association. Also, by the same dictionary, in linguistics, the adjective thematic denotes a word that is the theme of a sentence. In grammar, it is of or relating to the stem or root of a word. Very often, there is a need to consult Strong’s Concordance and the Hebrew and Greek lexicons to fully understand the association between words that are thematic in the Bible.

I am happy to expound further.
