The mouth of the righteous brings forth wisdom, but the perverse tongue will be cut off.
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.
Commenting on Proverbs 10:31-32
The mouth of the just bringeth forth wisdom,.... As the earth brings forth its increase, and a tree brings forth its fruit; hence speech is called the fruit of the lips; wisdom is good fruit; a good man is comparable to the fruitful earth, and to a good tree; whose mouth brings forth wise things in abundance, which are very pleasant and profitable; not worldly...
bringeth forth--literally, "germinates" as a plant. froward--(Compare Pro 2:12, Pro 2:14). cut off--as an unproductive plant.
