Enemy
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.
