Sirach 8:15 CPDV

¹³  You should not kindle the coals of sinners by arguing with them. For you might be scorched by the flame from the fire of their sins.

¹⁴  You should not stand against the face of a contemptuous person, otherwise he may sit down as if waiting in ambush against your words.

¹⁵  You should not lend to a man who is stronger than you. But if you do lend, consider it lost.

¹⁶  You should not promise beyond your ability. But if you do promise, consider how to fulfill it.

¹⁷  You should not judge against a judge. For he judges according to what is just.
