Ecclesiasticus / Sirach - Chapter 8 Vs 1-19
1 Do not try conclusions with anyone influential, in case you later fall into his clutches.
2 Do not quarrel with anyone rich, in case he puts his weight against you; for gold has destroyed many, and has swayed the hearts of kings.
3 Do not argue with anyone argumentative, do not pile wood on that fire.
4 Do not joke with anyone uncouth, for fear of hearing your ancestors insulted.
5 Do not revile a repentant sinner; remember that we all are guilty.
6 Do not despise anyone in old age; after all, some of us too are growing old.
7 Do not gloat over anyone's death; remember that we all have to die.
8 Do not scorn the discourse of the wise, but make yourself familiar with their maxims, since from these you will learn the theory and the art of serving the great.
9 Do not dismiss what the old people have to say, for they too were taught by their parents; from them you will learn how to think, and the art of the timely answer.
10 Do not kindle the coals of the sinner, in case you scorch yourself in his blaze.
11 Refuse to be provoked by the insolent, for fear that such a one try to trap you in your words.
12 Do not lend to anyone who is stronger than you are -- if you do lend, resign yourself to loss.
13 Do not stand surety beyond your means; if you do stand surety, be prepared to pay up.
16 Do not argue with a quick-tempered man, do not go with him where there are no other people, since blood counts for nothing in his eyes, and where no help is to be had, he will strike you down.
17 Do not ask a fool for advice, since a fool will not be able to keep a confidence.
18 In a stranger's presence do nothing that should be kept secret, since you cannot tell what use the stranger will make of it.
19 Do not open your heart to all comers, nor lay claim to their goodoffices.
