15Foolishness is bound in the heart of a child; but the rod of correction shall drive it far from him. 16He that oppresseth the poor to increase his riches, and he that giveth to the rich, shall surely come to want. 17Bow down thine ear, and hear the words of the wise, and apply thine heart unto my knowledge. 18For it is a pleasant thing if thou keep them within thee; they shall withal be fitted in thy lips.19That thy trust may be in the LORD, I have made known to thee this day, even to thee. 20Have not I written to thee excellent things in counsels and knowledge, 21That 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?
