'Enemy' in the Bible

If I have done evil to him who was at peace with me,Or without cause robbed him who was my enemy,

Let the enemy pursue me and overtake me;And let him trample my life to the groundAnd lay my honor in the dust. Selah.

Out of the mouths of infants and nursing babes You have established strengthBecause of Your adversaries,That You might silence the enemy and make the revengeful cease.

The enemy has been cut off and has vanished in everlasting ruins,You have uprooted their cities;The very memory of them has perished.

How long must I take counsel in my soul,Having sorrow in my heart day after day?How long will my enemy exalt himself and triumph over me?

And my enemy will say, “I have overcome him,”And my adversaries will rejoice when I am shaken.

He rescued me from my strong enemy,And from those who hated me, for they were too strong for me.

And You have not given me into the hand of the enemy;You have set my feet in a broad place.

By this I know that You favor and delight in me,Because my enemy does not shout in triumph over me.

I will say to God my rock, “Why have You forgotten me?Why do I go mourning because of the oppression of the enemy?”

For You are the God of my strength [my stronghold—in whom I take refuge]; why have You rejected me?Why do I go mourning because of the oppression of the enemy?

You make us turn back from the enemy,And those who hate us have taken spoil for themselves.

Because of the voice of the taunter and reviler,Because of the presence of the enemy and the avenger.

Because of the voice of the enemy,Because of the pressure of the wicked;For they bring down trouble on me,And in anger they persecute me.

For it is not an enemy who taunts me—Then I could bear it;Nor is it one who has hated me who insolently exalts himself against me—Then I could hide from him.

Hear my voice, O God, in my complaint;Guard my life from the terror of the enemy.

When you lie down [to rest] among the sheepfolds,You [Israel] are like the wings of a dove [of victory] overlaid with silver,Its feathers glistening with gold [trophies taken from the enemy].

O God, how long will the adversary scoff?Is the enemy to revile Your name forever?

Remember this, O Lord, the enemy has scoffed,And a foolish and impious people has spurned Your name.

They did not remember [the miracles worked by] His [powerful] hand,Nor the day when He redeemed them from the enemy,

“The enemy will not outwit him,Nor will the wicked man afflict or humiliate him.

So He saved them from the hand of the one that hated them,And redeemed them from the hand of the [Egyptian] enemy.

For the enemy has persecuted me,He has crushed my life down to the ground;He has made me dwell in dark places, like those who have been long dead.
