'Adversary' in the Bible

if I have done harm to one at peace with meor have plundered my adversary without cause,

Thou causest us to turn backward from an adversary, And those hating us, Have spoiled for themselves.

Be gracious to me, O God, for man has trampled on me;All day long the adversary oppresses and torments me.

O give us help against the adversary,For deliverance by man is in vain.

For You have been a shelter and a refuge for me,A strong tower against the enemy.

O God, how long shall the adversary reproach? shall the enemy blaspheme thy name for ever?

They did not remember his power the day he delivered them from their adversary,

Then he sent his might into captivity and his glory into the control of the adversary.

You turn back his sword from the adversary, and have not sustained him in battle.

He saved them from the hand of the adversary;He redeemed them from the hand of the enemy.

Let the redeemed of Jehovah say, Whom He redeemed from the hand of an adversary.

Oh give us help against the adversary,For deliverance by man is in vain.

Appoint Thou over him the wicked, And an adversary standeth at his right hand.

You [my enemy] pushed me violently so that I was falling,But the Lord helped me.
