CLV(i)
4 The words of a man's mouth are deep waters; The fountain of wisdom is a watercourse bubbling forth.
5 To show partiality to the wicked is not good, Or to turn aside the righteous in judgment."
6 The lips of a stupid man bring him into contention, And his mouth calls for beatings."
7 The mouth of a stupid man is his undoing, And his lips are a trap for his soul."
