Qof (or qoph, khof, or Kuf) is the nineteenth letter of the Hebrew Alphabet. It signifies the number one hundred.
In Hebrew, Qof means “ape,” “monkey” or “baboon,” while in Aramaic, it means “the back of the head” or “the eye of a needle.” Qof is the symbol of both the sacred Kedushah (“holiness”), and the profane Klipah (“husk,” metaphysical barriers between ourselves and the Light of Christ). It is the first letter in the word holy, Kadosh. The letter Qof represents the constant movement of the cycles of nature: changing seasons, monthly and yearly cycles.
In Kabbalah, it is the extended left leg and head that create the difference between life and death. It can represent our ability to overcome our animalistic nature to emulate the image of the Creator, to grow in the Grace of Jesus Christ. Qof is the constant movement, circulation, and change needed to evolve and realize our true spiritual nature through teshuvah.
