An enemy in the Bible refers to people who are in the love of evil and the false thinking that springs from evil. On a deeper level it refers to the forces of hell itself, and on an abstract level it refers to evil itself and falsity itself – which are, obviously, the ultimate enemies we have to fight.

11. Whatsoever things he saw signifies their understanding enlightened. This is evident from the signification of "seeing," as being to understand (See Arcana Coelestia, n. 2150, 2325, 2807, 3764, 3863, 3869, 4403-4421, 10705); here, to understand from enlightenment, because the things of the church and of heaven are treated of, which are not understood and perceived except from enlightenment; for things of the church and of heaven, which are called spiritual things, do not enter into man's understanding, except by means of the light of heaven, and the light of heaven enlightens the understanding. For this reason the Word, in which are contained the things of the church and of heaven, cannot be understood except by one who is enlightened, and those only are enlightened who are in the affection of truth from good, thus who are in love to the Lord and in charity towards the neighbor. This good is spiritual good, with which and from which is the light of heaven, which enlightens.
