This cipher is sometimes erroneously labelled as "Jewish" or "Hebrew" by popular numerology calculators, such as Gematrix and Gematrinator. A third type of gematria is known as 'Ordinal' gematria; this assigns a numerical value to each letter according to its place in the alphabet rather than its individual value. For example, 'A' would be equal to 1, 'B' would be equal to 2 and so on. This system can be applied just like Hebrew or Greek gematria but produces different results due to its unique numbering system. Word-based numerology probably began in 8th century BCE Mesopotamia; Greeks practised isopsephia (letter-based calculation) from the 5th century BCE. Hebrew gematria only arrived in c.100 BCE, yet soon grew in complexity. Unsurprisingly, it became an indispensable tool of Jewish mystics (kabbalists) down the ages. Similar to how different systems of gematria reveal deeper levels of understanding Torah and its hidden structures, there are along with the normative alphabet other alternative Kabbalistic alphabets that serves the same function. Through a logical sequence of exchanging letters these alphabets reveal inner dimensions of Torah not readily perceived. Another form of gematria, termed the reduced value system, is based on the decimal system, where every letter of ten and above reduces to one digit, its numerical lowest common denominator. The fact that mathematics itself is based on the decimal system of ten is of course extremely important. The number ten is highly symbolic and significant in Torah and appears in virtually all manifestations of Jewish tradition. Through using this easy to use program you can type in a word in Hebrew and virtually instantaneously see written out all the places in theTanach, the 24 books of the Bible, where this word, name or phrase appears. By studying these appearances we begin to see connections we may have never seen before. This device is used literally hundreds of times in the Talmud to shed light on issues ranging from Jewish law, to the alluded, allegorical and mystical meaning of the text. Quite simply it is the way we "connect the dots" of Torah and life itself.
