In the nineteenth chapter certain vagabond Jews pronounced over those who had evil spirits the name of Jesus, and the evil spirits answered: "Jesus I know, and Paul I know, but who are ye?"
"And the man in whom the evil spirit was leaped on them so that they fled naked and wounded."
Paul, writing to the Corinthians, in the eighth chapter says; "I would not that ye should have fellowship with devils. Ye cannot drink the cup of the Lord and the cup of devils. Ye cannot be partakers of the Lord's table and the table of devils. Do we provoke the Lord to jealousy?"
In the eleventh chapter he says that long hair is the glory of woman, but that she ought to keep her head covered because of the angels.
In those intellectual days people believed in what were called the Incubi and the Succubi. The Incubi were male angels and the Succubi were female angels, and according to the belief of that time nothing so attracted the Incubi as the beautiful hair of women, and for this reason Paul said that women should keep their heads covered. Paul calls the Devil the "prince of the power of the air."
So in Jude we are told "that Michael, the archangel, when contending with the devil he disputed about the body of Moses, durst not bring against him a railing accusation, but said, 'The Lord rebuke thee.'" Was this devil with whom Michael contended a personification of evil, or a poem, or a myth?
In First Peter we are told to be sober, vigilant, "because your adversary, the Devil, as a roaring lion, walketh about, seeking whom he may devour."
Are people devoured by personifications or myths? Has an allegory an appetite, or is a poem a cannibal?
So in Ephesians we are warned not to give place to the Devil, and in the same book we are told: "Put on the whole armor of God, that ye may be able to stand against the wiles of the Devil."
And in Hebrews it is said that "him that had the power of death—that is, the Devil;" showing that the Devil has the power of death.
