The Angel Samael in the Garden of Eden, and his offspring. Lecture quote:

"...it is stated in the Zohar that it was not the serpent who tempted Eve. Instead, it was an angel who was riding on the serpent.

We have learned that Samael, THE ANGEL, descended from heaven riding on this Serpent at that time. All the creatures saw his image and fled from him. Then SAMAEL AND THE SERPENT approached the woman with words, and brought death upon the world. - Zohar

This is profoundly different from what is taught in Sunday schools. Samael is the name of an angel, a very important angel who unfortunately has been removed from the Christian religion and has been trampled in the mud in the Jewish tradition, but in the very scriptures it is stated that Samael is a great angel."
