Proverbs 17:4

An evildoer gives heed to lips of wickedness;

A liar gives ear to a destructive tongue.

Proverbs 17:20

He who has a crooked heart finds no good,

And he who is perverted in his tongue falls into evil.

Better is a poor man who walks in his integrity

Than he who is crooked in lips and is a fool.

Like a madman who shoots

Firebrands, arrows, and death,

So is the man who deceives his neighbor,

And says, “Am I not joking?”

A lying tongue hates those it crushes,

And a flattering mouth works ruin.
