Text: The 21st Hebrew letter, Shin (S or Sh), means literally only a tooth, but being the 21st letter in the alphabet and 3 times 7 being regarded by all Kabbalists as an extremely sacred numerical combination, we must look below this surface definition to grasp the esoteric significance of this mysterious letter with which numerous mystical ideas and magical rites have long and frequently been associated. Shin has been engraven upon phylacteries to remind devout Jews of omnipresent Deity. This letter varies somewhat in form. When a dot is placed over the left prong it is rendered Sin, an old Oriental title of the Moon. Exodus tells us of the Wilderness of Sin and while they were still roaming the desert they received the Law of Sinai.
