Sirach 27:1-3

Revised Standard Version

27 Many have committed sin for a trifle,^[a]
    and whoever seeks to get rich will avert his 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 man is not steadfast and zealous in the fear of the Lord,
    his house will be quickly overthrown.
