Revelation Gematria refers to the practice of interpreting the Book of Revelation (also known as the Apocalypse of John) using gematria, a form of Jewish numerology that assigns numerical values to words or phrases based on the letters of the Hebrew or Greek alphabet. In Hebrew, this concept might be referred to as גימטריה של חיזיון (Gimatria shel Chizyon). Gematria is often used to find hidden meanings or connections within texts, and when applied to the Book of Revelation, it can provide insights into the symbolic numbers and names found throughout the text. The Book of Revelation is rich with numerical symbolism, such as the number 666 (the "number of the beast"), which has been a subject of gematria analysis. This practice is not limited to Hebrew; similar techniques have been applied in Greek, as the Book of Revelation was originally written in Koine Greek. In Greek, gematria is sometimes referred to as ισοψηφία (isopsephia). The use of gematria in interpreting the Book of Revelation is a specialized field that combines biblical exegesis with numerical analysis, often leading to diverse and sometimes controversial interpretations.
