The lips of the wise disperse knowledge: but the heart of the foolish does not so.
All Commentaries on Proverbs 15:7 Go To Proverbs 15
Gregory The Dialogist
AD 604
The heart of the wise is always consistent, because, while it remains at peace in its upright convictions, it constantly urges itself to good deeds. But the heart of the fool is inconsistent, because, in exhibiting itself as variable and changeable, it never remains what it was. .
