Wisdom of Ben Sira 8:11-13

New Catholic Bible

¹¹ Refuse to be provoked by an insolent man,
    for he may seek to trap you in your own words.
¹² Do not lend to someone who is more powerful than you are;
    but if you do lend anything, write it off as a loss.
¹³ Do not stand surety beyond your resources,
    but should you do so, be prepared to pay.
