Daemon

the Greek form, rendered "devil" in the Authorized Version of
the New Testament. Daemons are spoken of as spiritual beings
(Matt. 8:16; 10:1; 12:43-45) at enmity with God, and as having a
certain power over man (James 2:19; Rev. 16:14). They recognize
our Lord as the Son of God (Matt. 8:20; Luke 4:41). They belong
to the number of those angels that "kept not their first
estate," "unclean spirits," "fallen angels," the angels of the
devil (Matt. 25:41; Rev. 12:7-9). They are the "principalities
and powers" against which we must "wrestle" (Eph. 6:12).
