Gematria is a polarizing topic. While many love it, many others view it with skepticism.

What is the purpose of gematria?

Can we truly learn anything from the numerical representation of words?

What is beneath these creative yet apparently simplistic interpretations?


While jointly pursuing semichah and a PhD in mathematics, it seemed natural for Elie Feder to love gematria. However, he was bothered by these compelling questions. That is, until he discovered the purpose of gematria.


Gematria Refigured presents the discoveries that led to the author’s transformation from a gematria skeptic to a gematria lover. It develops a theory which elucidates how the Torah and Chazal use gematria to direct us toward a very specific type of idea. Through its many examples, this work illustrates how gematria can help us uncover novel insights, while providing interesting and clearly formulated perspectives into many mitzvos, themes, and stories in Tanach.
