The Mouth in Proverbs

10:11 The mouth of the righteous is a well of life,
But violence covers the mouth of the wicked.

10:21 The lips of the righteous feed many,
But fools die for lack of wisdom.

11:9 The hypocrite with his mouth destroys his neighbor,
But through knowledge the righteous will be delivered.

15:1 A soft answer turns away wrath,
But a harsh word stirs up anger.

15:4 A wholesome tongue is a tree of life,
But perverseness in it breaks the spirit.

16:24 Pleasant words are like a honeycomb,
Sweetness to the soul and health to the bones.

20:19 He who goes about as a talebearer reveals secrets;
Therefore do not associate with one who flatters with his lips.

22:10 Cast out the scoffer, and contention will leave;
Yes, strife and reproach will cease.

22:11 He who loves purity of heart
And has grace on his lips,
The king will be his friend.

26:18-20 Like a madman who throws firebrands, arrows, and death,
Is the man who deceives his neighbor,
And says, “I was only joking!”
Where there is no wood, the fire goes out;
And where there is no talebearer, strife ceases.

26:28 A lying tongue hates those who are crushed by it,
And a flattering mouth works ruin.

28:23 He who rebukes a man will find more favor afterward
Than he who flatters with the tongue.
