Psalm 17:3-5

Revised Standard Version Catholic Edition

³ If thou triest my heart, if thou visitest me by night,
    if thou testest me, thou wilt find no wickedness in me;
    my mouth does not transgress.
⁴ With regard to the works of men, by the word of thy lips
    I have avoided the ways of the violent.
⁵ My steps have held fast to thy paths,
    my feet have not slipped.
