Prayer for Wisdom and Forgiveness

To the Chief Musician. To Jeduthun. A Psalm of David.
  1I said, “I will guard my ways,
   Lest I sin with my tongue;
   I will restrain my mouth with a muzzle,
   While the wicked are before me.”
   2I was mute with silence,
   I held my peace even from good;
   And my sorrow was stirred up.
   3My heart was hot within me;
   While I was musing, the fire burned.
   Then I spoke with my tongue:
  4“Lord, make me to know my end,
   And what is the measure of my days,
   That I may know how frail I am.
   5Indeed, You have made my days as handbreadths,
   And my age is as nothing before You;
   Certainly every man at his best state is but vapor.
   6Surely every man walks about like a shadow;
   Surely they busy themselves in vain;
   He heaps up riches,
   And does not know who will gather them.
  7“And now, Lord, what do I wait for?
   My hope is in You.
   8Deliver me from all my transgressions;
   Do not make me the reproach of the foolish.
   9I was mute, I did not open my mouth,
   Because it was You who did it.
   10Remove Your plague from me;
   I am consumed by the blow of Your hand.
   11When with rebukes You correct man for iniquity,
   You make his beauty melt away like a moth;
   Surely every man is vapor.
  12“Hear my prayer, O Lord,
   And give ear to my cry;
   Do not be silent at my tears;
   For I am a stranger with You,
   A sojourner, as all my fathers were.
   13Remove Your gaze from me, that I may regain strength,
   Before I go away and am no more.”
