'Enemy' in the Bible

“Your right hand, O Lord, is glorious 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 satisfied against them;I will draw my sword, my hand shall dispossess them and drive them out.’

But if you will indeed listen to and truly obey His voice and do everything that I say, then I will be an enemy to your enemies and an adversary to your adversaries.
