Psalm 19:11-13

Revised Standard Version Catholic Edition

¹¹ Moreover by them is thy servant warned;
    in keeping them there is great reward.
¹² But who can discern his errors?
    Clear thou me from hidden faults.
¹³ Keep back thy servant also from presumptuous sins;
    let them not have dominion over me!
Then I shall be blameless,
    and innocent of great transgression.
