'Enemy' in the Bible

Lord, Your right hand is glorious in power.Lord, Your right hand shattered the enemy.

The enemy said:“I will pursue, I will overtake,I will divide the spoil.My desire will be gratified at their expense.I will draw my sword;my hand will destroy them.”

But if you will carefully obey him and do everything I say, then I will be an enemy to your enemies and a foe to your foes.
