Proverbs 22:17-21

KJV(i) 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 within 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?
