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.

698. In addition to the hells there are also vastations, about which much is stated in the Word. For a person brings with him into the next life, as the result of sins of his own doing, countless evils and falsities which he accumulates and couples to himself. Even people who have led upright lives do so. Before these can be raised up into heaven their evils and falsities must be dispersed, and this dispersing is called vastation. There are many kinds of vastation, and the time they last may be quite long or quite short. Some people are taken off to heaven within a fairly short period of time, some immediately after death.
