Ben Sira 8:10-19

10 Kindle not the coals of a sinner, lest thou be burnt with the flame of his fire.
11 Rise not up in anger at the presence of an injurious person, lest he lie in wait to entrap thee in thy words
12 Lend not unto him that is mightier than thyself; for if thou lendest him, count it but lost.
13 Be not surety above thy power: for if thou be surety, take care to pay it.
14 Go not to law with a judge; for they will judge for him according to his honour.
15 Travel not by the way with a bold fellow, lest he become grievous unto thee: for he will do according to his own will, and thou shalt perish with him through his folly.
16 Strive not with an angry man, and go not with him into a solitary place: for blood is as nothing in his sight, and where there is no help, he will overthrow thee.
17 Consult not with a fool; for he cannot keep counsel.
18 Do no secret thing before a stranger; for thou knowest not what he will bring forth.
19 Open not thine heart to every man, lest he requite thee with a shrewd turn.
