Psalm 40: Do not linger

I've waited for You for so long, and You turned to me and heard my cry.
  You brought me up from the tumultuous pit, from the miry clay,
     and set my feet upon a rock, placing a new song within my mouth.

Joyous is the one who trusts in You, who does not turn to the arrogant and fall away.
Many things have You done, many wondrous actions.

Behold I come with a roll of book, written for me.
I find strength from doing Your will, Your teachings are deep within me.
  Do not withhold Your loving-kindness.
   May Your mercy and truth preserve me, for numerous evils surround me.
    My ways have overtaken me, I’m unable to see, my heart has left me.

Please deliver me, hurry, and help me.
   I stand poor and needy.
    You Who are my help and my deliverer, please, do not linger.
