Proverbs 18:4, 6-8, 13, 21 NKJV
4 The words of a man’s mouth are deep waters; The wellspring of wisdom is a flowing brook.
6 A fool’s lips enter into contention, And his mouth calls for blows.
7 A fool’s mouth is his destruction, And his lips are the snare of his soul.
8 The words of a talebearer are like tasty trifles, And they go down into the inmost body.
13 He who answers a matter before he hears it, It is folly and shame to him.
21 Death and life are in the power of the tongue, And those who love it will eat its fruit.
