'Enemy' in the Bible

“Your right hand, O Lord, is majestic in power,Your right hand, O Lord, shatters the enemy.

“The enemy said, ‘I will pursue, I will overtake, I will divide the spoil;My desire shall be gratified against them;I will draw out my sword, my hand will destroy them.’

But if you truly obey his voice and do all that I say, then I will be an enemy to your enemies and an adversary to your adversaries.
