That I might make thee know the certainty of the words of truth; that thou mightiest answer the words of truth to them that send unto thee?
– Proverbs 22:21
[T]his verse explains and expands on the verse before it, and concludes Solomon’s introduction to “The Words of the Wise.” Various benefits of wisdom appear throughout Proverbs. Here, the method of instruction is to the end of establishing the learner in truth, so he may in turn speak truly to others. The wisdom to be a faithful messenger is one application of this verse (Proverbs 25:13). More generally, the one who acquires wisdom is equipped to impart wisdom to others.
