From Proverbs 10:32: “The lips of the righteous know what is acceptable, but the mouth of the wicked speaketh frowardness.” The righteous shows kind consideration when he speaks. He knows what is acceptable because he has studied the other person and knows something of their state. He knows how different words would affect him.
The wicked also knows of the other but speaks away from the appropriate answer (froward means away from). So the wicked shows hurtful consideration, the desire to oppose.
Verse 11: “The mouth of a righteous man is a well of life, but violence covereth the mouth of the wicked” A well has 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. When he gives answers they are healthful, as water is healthful.
If there is any healthful thing within the wicked, it is inaccessible because the well is covered. He does not want to give out health but harm. Obvious to all who see is the violence that covers his mouth. It is always on top, always presenting to people.
