'Enemy' in the Bible

"And if your people Israel are defeated before an enemy because they have sinned against you and they repent and confess your name and pray and plead before you in this house,

"If there is a famine in the land; if there is disease, blight, mildew, locust, and caterpillar; if it happens that his enemy lays siege to him in the land [and] his gates; any kind of plague, any kind of disease,

"When your people go out to battle against their enemy according to the way that you have sent them, and they pray to you toward this city that you have chosen and the house that I have built for your name,

When they sin against you--for there is no person who does not sin--and you become angry with them and place them before their enemy that they carry them away as captives to a land far or near,

But even still, you yourself go, do! Be strong for the battle [else] God will make you stumble before the enemy! For there is power with God to help and to cause stumbling."

And under their hand [were] army troops [numbering] three hundred and seven thousand five hundred who could make war with power and strength to help the king against an enemy.
