Angels-USIEL

Usiel (Strength of God) is generally considered a fallen angel and
among those who wedded human wives and begat giants. He is also
listed as the fifth of the ten unholy sefiroth. According to the Book of
the Angel Raziel, Usiel is among the seven angels before the throne of
God, and among the nine set over the four winds. A conjuration of
Usiel and an accounting of his adjunct princes are found in The Key to
Faust’s Threefold Harrowing of Hell. Milton regards Usiel as an “unfallen”
angel, belonging to the order of virtues, as well as one of Gabriel’s
lieutenants during Satan’s rebellion.
