Samael (Hebrew: סמאל, “Venom of God” or “Poison of God,” also Sammael or Samil) is an important archangel in Talmudic and post-Talmudic lore, a figure who is an accuser (satan),seducer and destroyer, and has been regarded as both good and evil. Rabbinical writings describe Samael as the guardian angel of Esau and a patron of Edom (or, the Roman empire).
He is considered in Talmudic texts to be a member of the heavenly host (with often grim and destructive duties). One of Samael’s greatest roles in Jewish lore is that of the main archangel of death. He remains one of Yahweh’s servants even though he wants men to do evil. As an angel, Samael resides in the seventh heaven, although he is declared to be the chief angel of the fifth heaven, the reason for this being the presence of the throne of glory in the fifth heaven.
