A kind of occult theosophy or traditional interpretation of
   the Scriptures among Jewish rabbis and certain mediaeval Christians,
   which treats of the nature of god and the mystery of human existence.
   It assumes that every letter, word, number, and accent of Scripture
   contains a hidden sense; and it teaches the methods of interpretation
   for ascertaining these occult meanings. The cabalists pretend even to
   foretell events by this means.
