In Hebrew, ‘the adversary’; and as such he appears in Job as one of the sons of God, delegated to inform God about human frailties. Later he becomes a malevolent being (1 Chron. 21: 1), and the enemy of God over Jesus (Luke 22: 3). He thus becomes the Devil (diabolos in Greek), identified with Beelzebub (Matt. 12: 26). Satan is said to have a battalion of demons who may enter human beings (Luke 9: 42) and may tempt them to evil (Jas. 2: 19). In the gospel of John there are no lesser demons and Jesus works no exorcisms; the principals alone, Jesus and the Devil, engage in conflict (John 13: 2) but eventually according to Revelation Satan will perish in a lake of fire (Rev. 20: 10–15).
