Proverbs 15:7 - Matthew Poole's English Annotations on the Holy Bible

Disperse knowledge; freely communicate to others what they know, as they have opportunity. Doeth not so; either because he hath no knowledge to disperse, or because he hath not a heart to perform his duty, or to do good to others. Or, as others render it, and as the last Hebrew word is rendered, Genesis 42:34, and elsewhere, is not right; or the place may be rendered, the heart of the foolish (understand out of the former clause, as is very usual, disperseth by his lips) that which is not right; foolish and corrupt discourse, which is fitly opposed to knowledge.
