'Enemy' in the Bible

And if thy people Israel be put to the worse before the enemy, because they have sinned against thee, and shall turn again and confess thy name, and pray, and make supplication before thee in this house;

If they have sinned against thee (for there is no man that sinneth not), and thou be angry with them, and give them up to the enemy, and they have carried them away captives unto a land far off or near;

But if thou wilt go, do it; be strong for the battle: God will make thee fall before the enemy, for there is with God power to help and to cast down.

And under their hand was an army-host of three hundred and seven thousand five hundred, that made war with mighty power to help the king against the enemy.
