the Greek form, rendered "devil" in the Authorized Version of the New Testament. Daemons are spoken of as spiritual beings ( Matthew 8:16 ; 10:1 ; 12:43-45 ) at enmity with God, and as having a certain power over man ( James 2:19 ; Revelation 16:14 ). They recognize our Lord as the Son of God ( Matthew 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 ( Matthew 25:41 ; Revelation 12:7-9 ). They are the "principalities and powers" against which we must "wrestle" ( Ephesians 6:12 ).
