Psalms 19:11-14 NIV
By them your servant is warned;
in keeping them there is great reward.
But who can discern their own errors?
Forgive my hidden faults.
Keep your servant also from willful sins;
may they not rule over me.
Then I will be blameless,
innocent of great transgression.
May these words of my mouth and this meditation of my heart
be pleasing in your sight,
LORD, my Rock and my Redeemer.
NIV: New International Version
