Proverbs 22:17-21

Bow down thine ear, and hear the words of the wise, and apply thine heart unto my knowledge. For it is a pleasant thing if thou keep them within thee; they shall withal be fitted in thy lips. That thy trust may be in the Lord, I have made known to thee this day, even to thee. Have not I written to thee excellent things in counsels and knowledge, 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?

Does the written word communicate the words of truth with certainty to the individual (thee = you singular) reader?
