Apocrypha
The Book of Enoch contains references to Satariel, thought also to be Sataniel and Satan'el (etymology dating back to Babylonian origins). The similar spellings mirror that of his angelic brethren Michael, Raphael, Uriel and Gabriel, previous to the fall from Heaven.
The Second Book of Enoch, also called the Slavonic Book of Enoch, contains references to a Watcher (Grigori) called Satanael. It is a pseudepigraphic text of an uncertain date and unknown authorship. The text describes Satanael as being the prince of the Grigori who was cast out of heaven and an evil spirit who knew the difference between what was "righteous" and "sinful". A similar story is found in the book of 1 Enoch; however, in that book, the leader of the Grigori is called Semjâzâ.
In the Book of Wisdom, the devil is represented as the being who brought death into the world.
In the Ascension of Isaiah and the Life of Adam and Eve, Satan rules over a host of angels.
Mastema, in the Book of Jubilees, induces God to test Abraham through the sacrifice of Isaac. He is identical to Satan in both name and nature.
