The Shem HaMephorash (Hebrew: שם המפורש, alternatively Shem ha-Mephorash or Schemhamphoras), meaning the explicit name, is an originally Tannaitic term[1] describing a hidden name of God in Kabbalah (including Christian and Hermetic variants), and in some more mainstream Jewish discourses. It is composed of either 4, 12, 22, 42, or 72 letters (or triads of letters), the last version being the most common.[2][3][4][5][6][7][8]
