Charles Ellicott Commentary Proverbs 22:21

"To make thee know the certainty of the words of truth, That thou mayest carry back words of truth to them that send thee?" — Proverbs 22:21 (ASV)

That thou mightest answer the words of truth to them that send unto thee? This rendering is somewhat doubtful, but seems to give the best sense to the passage. The scholar is to be instructed not for his own profit alone, but in order that he may be able to teach others also (Compare to 1 Peter 3:15).
