13:1 There is great hope of those that reverence their parents. There is little hope of any who will not hear those that deal faithfully with them. 2. By our words we must be justified or condemned, Mt 12:37. 3. He that thinks before he speaks, that suppresses evil if he have thought it, keeps his soul from a great deal both of guilt and grief. Many a one is ruined by an ungoverned tongue. 4. The slothful desire the gains the diligent get, but hate the pains the diligent take; therefore they have nothing. This is especially true as to the soul. 5. Where sin reigns, the man is loathsome. If his conscience were awake, he would abhor himself, and repent in dust and ashes.

3. He … mouth … life—because evil speeches may provoke violence from others.

he that openeth wide his lips shall have destruction—On last clause, compare Pr 10:14.
