17. Incline thine ear, and hear the words of the wise, and apply thy heart unto my knowledge.
18. For it is a pleasant thing if thou keep them within thee: they shall be together fitted on thy lips.
19. That thy confidence may be in Jehovah, I have made them known to thee this day, even to thee.
20. Have not I written to thee excellent things, in counsels and knowledge,
21. that I might make thee know the certainty of the words of truth; that thou mightest carry back words of truth to them that send thee?
