Keep me from stupid sins

Psalm 19: 11-14 (MSG)

11-14 There’s more: God’s Word warns us of danger
    and directs us to hidden treasure.
Otherwise how will we find our way?
    Or know when we play the fool?
Clean the slate, God, so we can start the day fresh!
    Keep me from stupid sins,
    from thinking I can take over your work;
Then I can start this day sun-washed,
    scrubbed clean of the grime of sin.
These are the words in my mouth;
    these are what I chew on and pray.
Accept them when I place them
    on the morning altar,
O God, my Altar-Rock,
    God, Priest-of-My-Altar.
