10:11 The teaching of the righteous is a fountain of life,
but the speech of the wicked conceals violence.
10:13 Wisdom is found in the words of the discerning person,
but the one who lacks wisdom will be disciplined.
10:20 What the righteous say is like the best silver,
but what the wicked think is of little value.
10:21 The teaching of the righteous feeds many,
but fools die for lack of wisdom.
