Psalm 19:12-14 (NKJV)
12 Who can understand his errors? Cleanse me from secret faults.
13 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.
14 Let the words of my mouth and the meditation of my heart,
Be acceptable in Your sight,
O LORD, my strength and my Redeemer.
