'Enemy's' in the Bible

The enemy's cities have been reduced to permanent ruins; you destroyed their cities; all memory of the enemies has perished.

I continually look to the Lord for help, for he will free my feet from the enemy's net.

I will say to God, my rock,“Why have You forgotten me?Why must I go about in sorrowbecause of the enemy’s oppression?”

For You are the God of my refuge.Why have You rejected me?Why must I go about in sorrowbecause of the enemy’s oppression?

because of the enemy’s voice,because of the pressure of the wicked.For they bring down disaster on meand harass me in anger.

For the music director; a psalm of David. Listen to me, O God, as I offer my lament! Protect my life from the enemy's terrifying attacks.

And delivered his strength into captivity, and his glory into the enemy's hand.
