Proverbs 22:17 Bow down thine ear, and hear the words of the wise, and apply thine heart unto my knowledge. 22:18 For it is a pleasant thing if thou keep them within thee; they shall withal be fitted in thy lips. 22:19 That thy trust may be in the LORD, I have made known to thee this day, even to thee. 22:20 Have not I written to thee excellent things in counsels and knowledge, 22:21 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? Titus 1:9 Holding fast the faithful word as he hath been taught, that he may be able by sound doctrine both to exhort and to convince the gainsayers.
