18. A man void of understanding strikes hands,and becomes collateral in the presence of his neighbor.
19. He who loves disobedience loves strife.One who builds a high gate seeks destruction.
20. One who has a perverse heart doesn’t find prosperity,and one who has a deceitful tongue falls into trouble.
21. He who becomes the father of a fool grieves.The father of a fool has no joy.
22. A cheerful heart makes good medicine,but a crushed spirit dries up the bones.
