Proverbs 22:17-21 DBY

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?
