'Demon possessed', 'possessed', or 'vexed with a devil' (KJV) are expressions found in the Gospels. From the context it is clear that 'devil' or 'demon' possession refers to being ill, diseased, mentally or otherwise afflicted, or being blind, deaf, dumb or crippled (see Matthew 4:24; 8:16,28,33; 9:32; 12:22; 15:22; Mark 1:32; 5:15-18; Luke 8:36; John 10:21).

"Then they brought him a demon-possessed man who was blind and mute, and Jesus healed him, so that he could both talk and see." (Matthew 12:22).
