Mastema

Mastema is an angel who persecutes evil in Hebrew folklore. He carries out punishments for God. He tempts humans and tests their faith. He asked God to permit him to have demons as his subordinates. In the Zadokite Fragments and the Dead Sea Scrolls, he is the angel of disaster, the father of all evil, and a flatterer of God. His name is that of an arch-demon who first appears in the literature of Israel's Second Temple Period, as a personification of the Hebrew word "mastemah" (משטמה), meaning "hatred", "hostility", "enmity" or "persecution".
