Tzaphkiel (means to dream) or Zaphkiel is the Archangel of deep contemplation of God.
Tzaphqiel is the Archangel of Binah on the Kabbalistic Tree of Life, ruled by the name IHVH Elohim and ruling the angelic choir Aralim. Binah is the supreme feminine aspect in Kabbalah and Zaphqiel is its representative in the world of Briah. In Jewish mysticism and Western ritual magic, Zadkiel is associated with the planet Jupiter.

In the Kabbalah Tzaphkiel rules sphere 3 - Binah, which means "Understanding".
