Prayer for Relief from Our Tormentors

Psalms 56:3 (NKJV)
1 Be merciful to me, O God, for man would swallow me up;
Fighting all day he oppresses me.
2 My enemies would hound me all day,
For there are many who fight against me, O Most High.
3 Whenever I am afraid,
I will trust in You.
4 In God (I will praise His word),
In God I have put my trust;
I will not fear.
What can flesh do to me?
