Gematria is Jewish.
I'll just leave that here.
Gematria (/ɡəˈmeɪtriə/; Hebrew: גמטריא or gimatria גימטריה, plural גמטראות or גימטריאות, gimatriot)[1] is an alphanumeric code of assigning a numerical value to a name, word or phrase based on its letters. A single word can yield multiple values depending on the cipher used.
