Gematria (Rabbinic Hebrew ), is a system of assigning numerical value to an alphabet. The word Gematria is believed to have been formed from a metathesis of the Greek word grammateia ("play upon letters"), from gramma (letter) and literally means 'that which is written'[1]. It is extant in English since the 17th century from translations of works by Giovanni Pico della Mirandola. Although ostensibly derived from Greek, it is largely used in Jewish texts of Tanakh and Talmud, notably in those associated with the Kabbalah.
Some identify two forms of gematria: the "revealed" form, which is prevalent in many several hermeneutic methods found throughout Rabbinic literature, and the "mystical" form, a largely Kabbalistic practice.
Rabbi Eleazar Chisma[2] said: the laws of mixed bird offerings and the key to the calculations of menstruation days?these, these are the body of the halakhah. The calculation of the equinoxes and gematria are the desserts of wisdom.
There are several methods used to calculate the numerical value for the individual words, and psukim (verses).
Mispar hechrachi (absolute value) that uses full numerical value of the twenty-two letters.
Mispar gadol counts the final forms (sofit) of the Hebrew letters as a continuation of the numerical sequence for the alphabet, with the final letters assigned values from 500 to 900.
Mispar katan calculates the value of each letter, but truncates all of the zeros.
Mispar siduri (ordinal value) with each of the 22 letters given a value from one to twenty-two.
At Bash uses letter (of a word or phrase) exchanges with its opposite letter and then the result is calculated. Opposite letters are determined by substituting the first letter of the Hebrew alphabet (Aleph) with the last letter (Tav), the second letter (Bet) with the next to last (Shin), etc.
Mispar HaKadmi uses each letter as the sum of the all the standard gematria letter values preceding it. Therefore, the value of Aleph is 1, the value of Bet is 1+2=3, the value of Gimmel is 1+2+3=6, etc.
Mispar HaPerati calculates the value of each letter as the square of its standard gematria value. Therefore, the value of Aleph is 1*1=1, the value of Bet is 2*2=4, the value of gimmel is 3*3=9, etc.
Mispar Shemi (also Millui letter "filling"), uses the value of each letter as equal to the value of its name[3]. For example, the value of the letter Aleph is (1+30+80) = 111, Bet is (2+10+400) = 412, etc.
Mispar katan mispari (integral reduced value) is used where the total numerical value of a word is reduced to a single digit. If the sum of the value exceeds 9, the integer values of the total are repeatedly added to produce a single-digit number. The same value will be arrived at regardless of whether it is the absolute values, the ordinal values, or the reduced values that are being counted by methods above.
Albam exchanges letters, with the alphabet is divided in half, eleven letters in each section. The first letter of the first series is exchanged for the first letter of the second series, the second letter of the first series for the second letter of the second series and so forth.
Absolute value gematria
The most common form of gematria is used in the Talmud and Midrash, and elaborately by many post-Talmudic commentators. It involves reading words and sentences as numbers, assigning numerical instead of phonetic value to each letter of the Hebrew alphabet. When read as numbers, they can be compared and contrasted with other words or phrases. A commentary almost completely dedicated to gematria is Baal ha-Turim by RabbiJacob ben Asher.
Although use of techniques that correspond to gematria, which were part of the esoteric lore in Mesopotamia, are suggested to predate its use in Hebrew, this can only be attested to the eight century BCE[4] where as use of gematria is identified in the very first verses of Genesis claimed to be dated to the 12th century BCE.[5] The first attested use of gematria in Mesopotamia occurs in an inscription of Sargon II (727?707 BCE) stating that the king built the wall of Khorsabad 16,283 cubits long to correspond with the numerical value of his name.[6]
Gematria was borrowed into the Greek probably soon after their adoption of the Semitic wryting system. The extant examples of use in Greek come primarily for the Christian literature and, unlike rabbinic sources, is always explicitly stated as being used.[7]Plato (c. 427-347 BCE) offers a discussion of gematria in its simplest forms in Cratylus, where he claims that the "essential force" of a thing's name is to be found in its numerical value, with words and phrases of the same numerical value may be substituted in context without loss in meaning.
The Latin-script languages exhibit borrowing of gematria methods dating from the early Middle Ages after the use lapsed following the collapse of Roman Empire in the 5th century.
