17. A friend loves at all times, And a brother is born for adversity.
18. A man lacking heart shakes hands in a pledge, He becomes a guarantor for his friend.
19. He who loves transgression loves strife, He who exalts his door seeks destruction.
20. He who has a crooked heart finds no good, And he who has a perverse tongue falls into evil.
21. He who brings forth a fool has sorrow for it, And the father of a fool has no joy.
