'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 praise Your name,and they pray and plead for mercybefore You in this temple,

When they sin against You—for there is no one who does not sin—and You are angry with themand hand them over to the enemy,and their captors deport themto a distant or nearby country,

But if you go with them, do it! Be strong for battle! But God will make you stumble before the enemy, for God has the power to help or to make one stumble.”

Under their authority was an army of 307,500 equipped for combat, a powerful force to help the king against the enemy.
