17 Bow down thine ear, and hear the words of the wise, and apply thine heart unto my knowledge.
18 For it is a pleasant thing if thou keep them withina thee; they shall withal be fitted in thy lips.
19 That thy trust may be in the LORD, I have made 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 answer the words of truth to them that send unto thee?
