Psalms 19:11-14

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 wilful 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.
