Pro 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?
When we listen to God and gain wisdom and knowledge from Him it changes our
demeanor. It’s that pleasant thing and it’s what we reproduce (fitted in thy lips).
He’s done all of this so that we would know Him and trust Him (v.20) and so that
we can share these gifts with others (v.21).
