Proverbs 17:7, 15, 20, 23

Excellent speech is not becoming to a fool, Much less lying lips to a prince.

He who justifies the wicked, and he who condemns the just, Both of them alike are an abomination to the LORD.

He who has a deceitful heart finds no good, And he who has a perverse tongue falls into evil.

A wicked man accepts a bribe behind the back To pervert the ways of justice.
