20. In all your works, let a true word precede you, with steadfast counsel before every deed.
21. A wicked word can change the heart. From the heart four kinds of things arise: good and evil, life and death. And the tongue is continually their ruler. There is a man who is an astute teacher of many, and yet this is useless to his own soul.
22. A man of experience has taught many, and this is pleasant to his own soul.
23. Whoever speaks mere rhetoric is hateful; he will be deceived in every matter.
24. Grace is not given to him from the Lord. For he has been deprived of all wisdom.
25. There is a wise man who is wise within his own soul, and the fruit of his understanding is praiseworthy.
26. A wise man instructs his own people, and the fruit of his understanding is faithful.
