{37:21} 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.
{37:22} A man of experience has taught many, and this is pleasant to his own soul.
{37:23} Whoever speaks mere rhetoric is hateful; he will be deceived in every matter.
{37:24} Grace is not given to him from the Lord. For he has been deprived of all wisdom.
{37:25} There is a wise man who is wise within his own soul, and the fruit of his understanding is praiseworthy.

{37:16} whose soul is in agreement with your own soul, and who, when you falter in the dark, will share your sorrows.
{37:17} And establish a heart of good counsel within yourself. For there is nothing of greater usefulness to you than this.
{37:18} At any time, the soul of a holy man declares more truths than seven vigilant watchmen sitting in a high place.
{37:19} But concerning all things, pray to the Most High, so that he may direct your way in truth.
{37:20} In all your works, let a true word precede you, with steadfast counsel before every deed.
