'Enemy' in the Bible

"If your people Israel are defeated in a battle with their enemy because they have sinned against you, when they return to you and confess to you, pray, and in this Temple they ask you to show grace to them,

"When they sin against you because there isn't a single human being who doesn't sin and you become angry with them and deliver them over to their enemy, who takes them away captive to a land that's near or far away,

But if you do go, strengthen yourself for war. Do you think God will throw you down before the enemy, since God has the power both to help or to overthrow?"

Uzziah commanded an army of 307,500 who could fight formidably on behalf of the king against any enemy.
