Do not go to law with a judge because, due to his position, judgment will be given in his favor.
Do not travel with an adventurer lest he impose himself on you and, as he does whatever he pleases, you both perish through his folly.
Do not quarrel with a bad-tempered person nor get involved with him in a lonely place; blood counts for little in his eyes and, when he sees you defenseless, he will attack you.
Sirach 8:14-16
