Psalm 19:12-14 (NKJV)
"Who can understand his errors? Cleanse me from secret faults. Keep back Your servant also from presumptuous sins; Let them not have dominion over me. Then I shall be blameless, And I shall be innocent of great transgression. Let the words of my mouth and the meditation of my heart be acceptable in Your sight, O Lord, my strength and my Redeemer."
