Samyaza

Samyaza (Aramaic: שמיחזה, Greek: Σεμιαζά), also Semihazah, Shemyazaz, Shemyaza, Sêmîazâz, Semjâzâ, Samjâzâ, Semyaza, and Shemhazai, is a fallen angel of apocryphal Jewish and Christian tradition that ranked in the heavenly hierarchy as one of the Grigori (meaning "Watchers"). The name "Shemyaza(z)" means "the (or my) name has seen" or "he sees the name" (Michael Knibb). The interesting thing about the second interpretation is there is a tale about Semjâzâ knowing the explicit name of God and making a deal with a human (Istahar) to tell her the name.

Possible identification outside the Book of Enoch

Some suggest that Samyaza is most likely another name for Satan (Heb: 'the adversary'), who was originally an entity created in the service of God; he was the caretaker of God's throne, but later fell from the heavens because of his pride according to some Abrahamic traditions. Jesus states that he saw Satan fall from heaven like lightning in Luke 10:18.

Others say that Samyaza should not be mistaken for another name for Satan, who some believe was "cast out" from the heavens previously (reasons offered in the apocryphal Gospel of Bartholomew include the refusal to bow down to Adam). This interpretation points to Rev. 12:9 and Gen. 6:4 as depicting two separate falls from heaven, one of Satan being cast down, the other of the sons of God choosing to come to earth to take human wives.
