Proverbs 18:4 The words of a man’s mouth are as deep waters, and the wellspring of wisdom as a flowing brook.
5 It is not good to accept the person of the wicked, to overthrow the righteous in judgment.
6 A fool’s lips enter into contention, and his mouth calleth for strokes.
7 A fool’s mouth is his destruction, and his lips are the snare of his soul.
The words of a man come from the heart and one who is wise has wellspring of wisdom that gushes forth like a river but soothes like a gentle flowing brook. We see to that it is not good to allow the riches, influence, friends, or offices of a wicked man to pervert justice of the poor or of the righteous man. To listen to the ramblings of what a wicked person says is wrong. Also a fool would just assume enter into a fight rather reason with someone to solve a situation. A fool with his words causes only trouble because they are guided by his own selfish desires. His words will only bring destruction and snare his soul. We can see the contrast in these verses of how with the righteous the words are spoken to help but the words of a fool are spoken to tear down.
