Sirach 13:1-3

Revised Standard Version Catholic Edition

13 Whoever touches pitch will be defiled,
    and whoever associates with a proud man will become like him.
² Do not lift a weight beyond your strength,
    nor associate with a man mightier and richer than you.
How can the clay pot associate with the iron kettle?
    The pot will strike against it, and will itself be broken.
³ A rich man does wrong, and he even adds reproaches;
    a poor man suffers wrong, and he must add apologies.
