Hebrew name (קפציאל) [Qafsiel] - "The throne of God (El)".
Cassiel - is the Latin name of an archangel in post-biblical Judeo-Christian religion, particularly that of the Kabbalah. Unlike many other angels, Cassiel is known for simply watching the events of the cosmos unfold with little interference. He is the angel of solitude and tears, and is said to preside over the deaths of kings.
He is often included in lists as being one of the seven archangels and often associated with the Seventh Heaven. Cassiel is one of the archangels in Hebrew tradition (Ananiel, Barachiel, Chamuel, Gabriel, Jegudiel, Jophiel, Haniel, Michael, Oriphiel, Raguel, Raphael, Sariel, Simiel, Selaphiel, Uriel, Zadakiel etc.)
