Daemoniac
    one "possessed with a devil." In the days of our Lord and his
    apostles, evil spirits, "daemons," were mysteriously permitted
    by God to exercise an influence both over the souls and bodies
    of men, inflicting dumbness (Matt. 9:32), blindness (12:22),
    epilepsy (Mark 9:17-27), insanity (Matt. 8:28; Mark 5:1-5).
    Daemoniacs are frequently distinguished from those who are
    afflicted with ordinary bodily maladies (Mark 1:32; 16:17, 18;
    Luke 6:17, 18). The daemons speak in their own persons (Matt.
    8:29; Mark 1:23, 24; 5:7). This influence is clearly
    distinguished from the ordinary power of corruption and of
    temptation over men. In the daemoniac his personality seems to
    be destroyed, and his actions, words, and even thoughts to be
    overborne by the evil spirit (Mark, l.c.; Acts 19:15).
