The lips of the wise disperse knowledge: but the heart of the foolish doeth not so.

Wesley's Notes

15:7 Disperse - Freely communicate to others what they know.

Jamieson-Fausset-Brown Bible Commentary

7. (Compare Pr 10:20, 21).

heart . not so-not right, or vain.

Matthew Henry's Concise Commentary

15:3. Secret sins, services, and sorrows, are under God's eye. This speaks comfort to saints, and terror to sinners. 4. A good tongue is healing to wounded consciences, by comforting them; to sin-sick souls, by convincing them; and it reconciles parties at variance. 5. If instruction is despised, reprove men rather than suffer them to go on undisturbed in the way to ruin. 6. The wealth of worldly men increases their fears and suspicions, adds strength to their passions, and renders the fear of death more distressing. 7. We use knowledge aright when we disperse it; but the heart of the foolish has nothing to disperse that is good. 8,9. The wicked put other things in the stead of Christ's atonement, or in the place of holy obedience. Praying graces are his gift, and the work of his Spirit, with which he is well pleased. 10. He that hates reproof shall perish in his sins, since he would not be parted from them.
