Wisdom of Ben Sira 34:28-30

New Catholic Bible

²⁸ When one builds up and another tears down,
    what have they gotten out of it but hard work?
²⁹ When one prays and another curses,
    to whose voice will the Lord listen?
³⁰ If someone bathes after touching a corpse and then touches it again,
    what has been gained by washing?
