Sirach 34:29-31

New Revised Standard Version Catholic Edition

²⁹ When one prays and another curses,
    to whose voice will the Lord listen?
³⁰ If one washes after touching a corpse, and touches it again,
    what has been gained by washing?
³¹ So if one fasts for his sins,
    and goes again and does the same things,
who will listen to his prayer?
    And what has he gained by humbling himself?
