Samael

Samael (Hebrew: סמאל‎) (also Sammael and Samil) is an important archangel in Talmudic and post-Talmudic lore, a figure who is accuser, seducer and destroyer, and has been regarded as both good and evil. It is said that he was the guardian angel of Esau and a patron of the Roman empire.

He is considered in legend a member of the heavenly host (with often grim and destructive duties), in the New Testament named Satan and the chief of the evil spirits. One of Samael's greatest roles in Jewish lore is that of the angel of death. He remains one of the Lord's servants even though he appears to want men to do evil. As a good angel, Samael resides in the seventh heaven, although he is declared to be the chief angel of the fifth heaven.
