I'm praying this one, one of my favorites this week. I consider verse 1 to be one of my primary 'life verses' if you will:
27:1 The Lord is my light and my salvation;
whom shall I fear?
The Lord is the stronghold  of my life;
of whom shall I be afraid?
2 When evildoers assail me
to eat up my flesh,
my adversaries and foes,
it is they who stumble and fall.
3 Though an army encamp against me,
my heart shall not fear;
though war arise against me,
yet  I will be confident.
4 One thing have I asked of the Lord,
that will I seek after:
that I may dwell in the house of the Lord
all the days of my life,
to gaze upon the beauty of the Lord
and to inquire  in his temple.
5 For he will hide me in his shelter
in the day of trouble;
he will conceal me under the cover of his tent;
he will lift me high upon a rock.
6 And now my head shall be lifted up
above my enemies all around me,
and I will offer in his tent
sacrifices with shouts of joy;
I will sing and make melody to the Lord.
7 Hear, O Lord, when I cry aloud;
be gracious to me and answer me!
8 You have said, “Seek  my face.”
My heart says to you,
“Your face, Lord, do I seek.” 
9 Hide not your face from me.
Turn not your servant away in anger,
O you who have been my help.
Cast me not off; forsake me not,
O God of my salvation!
10 For my father and my mother have forsaken me,
but the Lord will take me in.
11 Teach me your way, O Lord,
and lead me on a level path
because of my enemies.
12 Give me not up to the will of my adversaries;
for false witnesses have risen against me,
and they breathe out violence.
13 I believe  that I shall look upon the goodness of the Lord
in the land of the living!
14 Wait for the Lord;
be strong, and let your heart take courage;
wait for the Lord!
