16. Be not surety above thy power: and if thou be surety, think as if thou wert to pay it.
17. Judge not against a judge: for he judgeth according to that which is just.
18. Go not on the way with a bold man, lest he burden thee with his evils: for he goeth according to his own will, and thou shalt perish together with his folly.
19. Quarrel not with a passionate man, and go not into the desert with a bold man: for blood is as nothing in his sight, and where there is no help he will overthrow thee.
