(Proverbs 10:32) “The lips of the righteous know what is acceptable, but the mouth of the wicked speaketh frowardness.” The righteous shows consideration; he knows what is acceptable because he has studied the other person and knows something of their state and knows how different words would effect him. The wicked also knows of the other but speaks away from the appropriate answer (FROward = away from). So the wicked shows hurtful consideration, the desire to oppose.
(v11) “the mouth of a righteous man is a well of life, but violence covereth the mouth of the wicked.” A well in an opening from which something must be drawn out. What good is inside the righteous must be drawn out, he is not quick with his answers. The answers are healthful, as water is healthful. If there is any healthful thing within the wicked, it is inaccessible because the well is covered. Obvious to all is the violence that covers his mouth. It is always on top, always presenting to people.
Lord help me, give me the grace to be a healthful speaker on behalf of others. Please do not let me do damage and violence with my mouth.
