Proverbs 22:19

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?
