Matthew Henry's Complete Bible Commentary

Verse 31

Note, 1. It is the character of a wise man that he is very willing to be reproved, and therefore chooses to converse with those that, both by their words and example, will show him what is amiss in him: The ear that can take the reproof will love the reprover. Faithful friendly reproofs are here called the reproofs of life, not only because they are to be given in a lively manner, and with a prudent zeal (and we must reprove by our lives as well as by our doctrine), but because, where they are well-taken, they are means of spiritual life, and lead to eternal life, and (as some think) to distinguish them from rebukes and reproaches for well-doing, which are rather reproofs of death, which we must not regard nor be influenced by. 2. Those that are so wise as to bear reproof well will hereby be made wiser (Proverbs 9:9), and come at length to be numbered among the wise men of the age, and will have both ability and authority to reprove and instruct others. Those that learn well, and obey well, are likely in time to teach well and rule well. MHBCC 644.33
