Sirach 8:11-13

New Revised Standard Version Catholic Edition

¹¹ Do not let the insolent bring you to your feet,
    or they may lie in ambush against your words.
¹² Do not lend to one who is stronger than you;
    but if you do lend anything, count it as a loss.
¹³ Do not give surety beyond your means;
    but if you give surety, be prepared to pay.
