Psalms 12:2

For they that are such serve not our Lord Jesus Christ, but their own belly; and by good words and fair speeches deceive the hearts of the simple.

Their tongue is as an arrow shot out; it speaketh deceit: one speaketh peaceably to his neighbour with his mouth, but in heart he layeth his wait.

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

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

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

For there is no faithfulness in their mouth; their inward part is very wickedness; their throat is an open sepulchre; they flatter with their tongue.

A double minded man is unstable in all his ways.

Draw me not away with the wicked, and with the workers of iniquity, which speak peace to their neighbours, but mischief is in their hearts.

For neither at any time used we flattering words, as ye know, nor a cloke of covetousness; God is witness:

Why boastest thou thyself in mischief, O mighty man? the goodness of God endureth continually. Thy 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 there shall be no more any vain vision nor flattering divination within the house of Israel.

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.

He that goeth about as a talebearer revealeth secrets: therefore meddle not with him that flattereth with his lips.

A man that flattereth his neighbour spreadeth a net for his feet.

Rid me, and deliver me from the hand of strange children, whose mouth speaketh vanity, and their right hand is a right hand of falsehood:

The words of his mouth were smoother than butter, but war was in his heart: his words were softer than oil, yet were they drawn swords.

They only consult to cast him down from his excellency: they delight in lies: they bless with their mouth, but they curse inwardly. Selah.

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.

Of Zebulun, such as went forth to battle, expert in war, with all instruments of war, fifty thousand, which could keep rank: they were not of double heart.

The words of his mouth are iniquity and deceit: he hath left off to be wise, and to do good. He deviseth mischief upon his bed; he setteth himself in a way that is not good; he abhorreth not evil.
