Psalm 18:13-15 Douay-Rheims 1899 American Edition (DRA)
13 Who can understand sins? from my secret ones cleanse me, O Lord:
14 And from those of others spare thy servant. If they shall have no dominion over me, then shall I be without spot: and I shall be cleansed from the greatest sin.
15 And the words of my mouth shall be such as may please: and the meditation of my heart always in thy sight. O Lord, my helper, and my redeemer.
