'Enemy' in the Bible

“If Your people Israel are defeated before an enemy because they have sinned against You, and they return to You and confess Your name, and pray and make supplication before You in this house,

“When they sin against You (for there is no man who does not sin) and You are angry with them and deliver them to an enemy, so that they take them away captive to a land far off or near,

But if you do go, do it, be strong for the battle; yet God will bring you down before the enemy, for God has power to help and to bring down.”

Under their direction was an elite army of 307,500, who could wage war with great power, to help the king against the enemy.
