Sprüche 10:31

21 The lips of the righteous edify many; But fools die through want of understanding.

Here, as before, men are judged of, and, accordingly, are justified or condemned, by their words, Mat 12:37. 1. It is both the proof and the praise of a man's wisdom and goodness that he speaks wisely and well. A good man, in his discourse, brings forth wisdom for the benefit of others. God gives him wisdom as a reward of his righteousness (Ecc 2:26), and he, in gratitude for that gift and justice to the giver, does good with it, and with his wise and pious discourses edifies many. He knows what is acceptable, what discourse will be pleasing to God (for that is it that he studies more than to oblige the company), and what will be agreeable both to the speaker and to the hearers, what will become him and benefit them, and that he will speak. 2. It is the sin, and will be the ruin, of a wicked man, that he speaks wickedly like himself. The mouth of the wicked speaks frowardness, that which is displeasing to God and provoking to those he converses with; and what is the issue of it? Why, the froward tongue shall be cut out, as surely as the flattering one, Psa 12:3.
