Ecclesiasticus 19
26 A man is known by his look, and a wise man, when thou meetest him, is known by his countenance. 27 The attire of the body, and the laughter of the teeth, and the gait of the man, shew what he is. 28 There is a lying rebuke in the anger of an injurious man: and there is a judgment that is not allowed to be good: and there is one that holdeth his peace, he is wise.
Ecclesiastes 7
3 It is better to go to the house of mourning, than to the house of feasting: for in that we are put in mind of the end of all, and the living thinketh what is to come. 4 Anger is better than laughter: because by the sadness of the countenance the mind of the offender is corrected. 5 The heart of the wise is where there is mourning, and the heart of fools where there is mirth.
6 It is better to be rebuked by a wise man, than to be deceived by the flattery of fools. 7 For as the crackling of thorns burning under a pot, so is the laughter of a fool: now this also is vanity.
Ecclesiasticus 21
22 Doctrine to a fool is as fetters on the feet, and like manacles on the right hand. 23 A fool lifteth up his voice in laughter: but a wise man will scarce laugh low to himself.
