Sirach 27:1-3

New Revised Standard Version Catholic Edition

27 Many have committed sin for gain,^[a]
    and those who seek to get rich will avert their eyes.
² As a stake is driven firmly into a fissure between stones,
    so sin is wedged in between selling and buying.
³ If a person is not steadfast in the fear of the Lord,
    his house will be quickly overthrown.
