18 is considered lucky primarily in Jewish tradition because it represents the Hebrew word "Chai," which means "life."
Here's a more detailed explanation:
-
Hebrew Numerology (Gematria): In Hebrew, each letter has a numerical value. The word "Chai" is spelled with the letters Chet (ח) and Yud (י). Chet has a numerical value of 8, and Yud has a numerical value of 10. Therefore, "Chai" (חַי) equals 8 + 10 = 18.
-
Symbolism of Life: Because the number 18 represents "Chai," it has become a symbol of life. This association makes it a lucky and auspicious number, particularly when giving gifts or donations.
-
Giving in Multiples of 18: It's common practice in Jewish communities to give charitable donations in multiples of 18. For example, giving $18, $36, $54, etc., is considered a meaningful and fortunate act, as it signifies giving "life" to a cause or person in need.
-
Significance in Jewish Culture: The number 18, and its association with "Chai," is deeply embedded in Jewish culture and tradition. It's seen as a positive and powerful symbol of hope, good fortune, and the enduring value of life.
In summary, the luck associated with the number 18 stems from its representation of "Chai," the Hebrew word for "life," making it a symbol of good fortune, especially in charitable giving within Jewish tradition.
