Psalms 11:3

His mouth is full of cursing and deceit and fraud: under his tongue is mischief and vanity.

The words of his mouth are iniquity and deceit: he hath left off to be wise, and to do good.

They also that seek after my life lay snares for me: and they that seek my hurt speak mischievous things, and imagine deceits all the day long.

And if he come to see me, he speaketh vanity: his heart gathereth iniquity to itself; when he goeth abroad, he telleth it.

Why boastest thou thyself in mischief, O mighty man? the goodness of God endureth continually. The tongue deviseth mischiefs; like a sharp razor, working deceitfully. Thou lovest evil more than good; and lying rather than to speak righteousness. Selah. Thou lovest all devouring words, O thou deceitful tongue.

For the sin of their mouth and the words of their lips let them even be taken in their pride: and for cursing and lying which they speak.

Whose mouth speaketh vanity, and their right hand is a right hand of falsehood.

Oh that I had in the wilderness a lodging place of wayfaring men; that I might leave my people, and go from them! for they be all adulterers, an assembly of treacherous men. And they bend their tongues like their bow for lies: but they are not valiant for the truth upon the earth; for they proceed from evil to evil, and they know not me, saith the LORD. Take ye heed every one of his neighbour, and trust ye not in any brother: for every brother will utterly supplant, and every neighbour will walk with slanders. And they will deceive every one his neighbour, and will not speak the truth: they have taught their tongue to speak lies, and weary themselves to commit iniquity. Thine habitation is in the midst of deceit; through deceit they refuse to know me, saith the LORD.
