Sirach 13:2-4

New Revised Standard Version Updated Edition

² Do not lift a weight too heavy for you
    or associate with one mightier and richer than you.
How can the clay pot associate with the iron kettle?
    The pot will strike against it and be smashed.
³ A rich person does wrong and even adds insults;
    a poor person suffers wrong and must add apologies.^(A)
4 Rich people^[a] will exploit you^[b] if you can be of use to them,
    but if you are in need they will abandon you.
