Wisdom of Ben Sira 13:2-4

New Catholic Bible

² Do not bear a burden too heavy for you,
    or associate with someone who is greater or wealthier than you.
How can the clay pot be used with the iron cauldron?
    When they collide, the pot will be smashed.
³ The rich man does wrong and boasts about it;
    the poor man is wronged and has to beg for forgiveness.
⁴ The rich man will exploit you if you can be useful to him,
    but if you are in need, he will abandon you.
