Proverbs 18:4-7

Thomson(i) 4 A speech in a man's heart is deep water; but a stream issueth forth and a flowing spring. 5 To respect the person of a wicked man is not good; nor is it consistent with piety to pervert justice in judgment. 6 The lips of a fool lead him into trouble; and his mouth when bold provoketh death. 7 The mouth of a fool is his destruction, and his lips are a snare for his soul.
