Psalm 17:3-5

New Revised Standard Version, Anglicised Catholic Edition

³ If you try my heart, if you visit me by night,
    if you test me, you will find no wickedness in me;
    my mouth does not transgress.
⁴ As for what others do, by the word of your lips
    I have avoided the ways of the violent.
⁵ My steps have held fast to your paths;
    my feet have not slipped.
