Mastema (Hebrew: מַשְׂטֵמָה Mastēmāh; Ge'ez: መሰቴማ Mesetēma) is an angel who persecutes evil in the Book of Jubilees. He carries out punishments for God, as well as tempting humans and testing their faith. 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. He is said to have become a fallen angel. He first appears in the literature of the Second Temple Period as a personification of the Hebrew word mastemah (מַשְׂטֵמָה), meaning "hatred", "hostility", "enmity", or "persecution".
